Blue routes are the ones that work.
Use your own state!
Multiples of 5 only, please. Nothing above 100 in the U.S. unless there is a "no speed limit" type road, and nothing below 20 without a good reason.
Here are route numbers 20 through 95 in Massachusetts, and whether it would work as a speed limit or not:
20: Too slow outside of Boston. And inside of Boston, traffic lights will be what slows you down.
25: Way too slow for a freeway.
30: Reasonable. Maybe a bit slow outside of MA 128.
35: Reasonable.
40: Reasonable, although a bit slow outside of Chelmsford.
45: Does not exist.
50: Does not exist.
55: Does not exist.
60: Way too fast, especially in an urban area.
65: Does not exist.
70: Too fast, even between 2 and 117.
75: Does not exist.
80: Way too fast for a non-freeway.
85: Way too fast for a non-freeway.
90: The Mass Pike is a bit too mountainous to be going 90.
95: 85+ is only for straight rural sections, which I-95 is not.
Now for New Hampshire, 25 to 95 (20 does not exist):
25: Too slow for a route that does not have urban areas.
30: Does not exist.
35: Does not exist.
40: Does not exist.
45: Reasonable, although a bit slow, considering that the route is mostly empty.
50: Does not exist.
55: Does not exist.
60: Does not exist.
65: Does not exist.
70: Does not exist.
75: Even though it's mostly rural, it's still too fast.
80: Does not exist.
85: Way too fast for a non-freeway through Exeter.
90: Does not exist.
95: 85+ is only for straight rural sections, which I-95 is not.
New Jersey:
NJ 20 - Even if it's in residential Paterson, it's too slow for a divided highway and too slow for an arterial anyway.
US 30 - Nope
NJ 35 - Hell no, too long and not enough residential areas
US 40 - It would be kinda slow in some areas... but it could work
NJ 45 - Between Mantua and Mullica Hill, as well as up until Woodstown, and finally all the way until you reach Salem, yes, but in those areas 45 is a bit too iffy
NJ 50 - Maybe. It passes through rural areas of Atlantic County, but it may be too fast for the residential areas that it does pass by
NJ 55 - Definitely. It's a freeway anyway.
NJ 70 - Besides the fact the highest speed limit in Jersey is 65, this is too much of an arterial to have a 70 MPH speed limit
I-80 - It'd be nice, considering it's an Interstate, but there's no way it would happen
NJ 90 - It's the Betsy Ross Bridge. There's nothing else to say.
I-95 - That's a bit extreme.
Kentucky tends to use x5 speed limits, so I'll stick to those.
US 25 -- yep, through the downtowns of most cities
KY 35 -- I think it has this speed limit in Sparta and in Warsaw.
US 45 -- yep, several places.
KY 55 -- for most of it.
I-65 -- yep.
I-75 -- should be, but our speed limit maximum is 70.
Colorado:
I-70 - Easily
CO 60 - mostly rural, so plausible
CO 55 - very plausible
US 50 - plausible somewhere
CO 45 - in Pueblo, maybe somewhere
US 40 - On Colfax Ave for sure
CO 35 - Entirely in Denver (Quebec St), so plausible
CO 30 - Entirely in Denver (Hampden Ave), so plausible
I-25 - A stretch, but you could argue this is the de facto speed limit between Colorado Blvd. and Sante Fe Dr. on most afternoons :-P
US 10, MN 15, MN 20 - Too slow.
MN 25 - Has a lot of sharp turns in the route, so at times this is reasonable.
MN 30, I-35 - Too slow.
MN 40 - Probably has some in-town segments.
MN 45 - Reasonable. This route is only two miles long anyway. :biggrin:
MN 50 - Reasonable.
MN 55 - Perfect.
MN 60 - Probably perfect as well - does have some flat, rural segments and quite a bit of expressway upgrading these days.
MN 65 - Posted 65 north of the Twin Cities to Cambridge as 4-lane expressway.
MN 70, US 75, MN 80, I-90, MN 95 - Too fast.
Virginia:
VA 20: maybe in one of the small towns it goes through
VA 25: doesn't exist
VA 30: in West Point, maybe
VA 35: too rural for the most part, but maybe in Courtland
VA 40: on the outskirts of some of the towns, but mostly no
VA 45: the segment in Goochland County actually is 45, but south of Cartersville is deservedly 55. Actually could be posted higher if not for state law
US 50: wouldn't surprise me if it is 50 somewhere, but don't know of anywhere for sure
VA 55: probably is in several places
US 60: I think there are a few places in the empty space between Powhatan and Amherst that are posted 60. If not, they could easily be, as could sections between I-295 and VA 30
VA 65/70/75/80: no, terrain issues
I-85: could be, but state laws and potholes say otherwise
VA 90: no
I-95: would be OK in a couple rural areas, but like I-85 state laws would dictate otherwise

Correct on both of those. Route 50 is posted at 50 mph for most of the segment between Paris and Gilbert's Corner, except of course for the segments passing through Upperville, Middleburg, and Aldie where it drops to 25 mph (and they mean it!). I even obey the 50-mph speed limit on that road. There may be other 50-mph segments on Route 50, but that's the one I can readily think of. West of Paris it's posted at 55; east of the roundabouts near Gilbert's Corner I'm not sure, and the widening project in eastern Loudoun County surely affects things too.
Lots of portions of Route 55 are posted at 55 mph. It also has a 70-mph segment (short concurrency with I-66 near Marshall and Delaplane where you pass Barrel Oak Winery).
Unfortunately, California's major north-south artery (I-5) would be one of the most excruciating drives on earth. It's miserable enough at 70. (Although at times in LA, 5 m.p.h. would be an improvement.)
CA 35 (Skyline Boulevard) would be rather slow but close to reasonable.
I-40 - way too slow
CA 45 - also slow, but closer to tolerable
US 50 - a bit slow for the freeway in Sacramento, a bit fast for some of the mountainous stretches in El Dorado County.
CA 55 (Costa Mesa Freeway) - close to normal
CA 60 (Pomona Freeway) - close to normal
CA 65 - close to normal
CA 70 - too fast for much of this route
CA 75 - pushing it
I-80 - close to actual speeds during low-traffic periods; too fast for Donner pass
CA 85 - pushing it

Oregon:
US 30/OR 35 - this is pretty reasonable for the Historic Columbia River Highway section (1 roadway, 2 different route numbers)
OR 70 - 2 lane rural highway in the middle of farming country, I bet most people drive 70 mph on it
But no luck on the few interstates we have, all weird numbers.
Oregon:
I-5 - Only for trucks coming down the Syskiyous.
OR 10 - Maybe during rush hour in Beaverton.
No 15
US 20 - Too slow
No 25
US 30 - Seems reasonable for the Mosier Curves, and decent for rush hour in Portland. Too slow otherwise.
OR 35 - Too slow
No 40-65
OR 70 - Would work
No 75-95
Louisiana:
20 - Definitely not I-20, on LA 20 maybe at the funky northbound transition at LA 24, or maybe downtown Thibodaux, but not as a whole
25 - LA 25 in Franklinton, but not the rest of the highway
30 - LA 30 - still too slow for the whole road, but the northern end at LSU and downtown Baton Rouge
35 - LA 35:maybe in parts of Church Point and Rayne
40 - not great as a whole for LA 40
45 - have not traveled LA 45, but this could work throughout. Bigger highway in New Orleans suburbs and a good speed limit south of the Intracoastal bridge
50 - I'm not sure you could get to 50 mph on this small stretch of hwy. Lot of things close to the shoulders of this 2 laner.
55 - definitely could work on LA 55. Far enough away from the city life in Houma and it is a connector to gulf coast communities
60 - may be a little too curvy on LA 60, but possible
65 - US 65 is mostly rural outside of Lake Providence and Tallulah, so for 90% of this hwy, yes
70 - not a good choice on LA 70 in the curvy swamp sections
75 - LA 75 is also a river road on the MS River banks, so 75 is a no go there
80 - no. US 80 goes through way too many medium sized towns and downtowns of large cities.
85 - you might be able to get to 85 mph on a straight stretch of LA 85, but not likely
90 - US 90's freeway portions, but that's about it
95 - no chance on LA 95. zigzaggy road and many turns
Quote from: 1 on January 28, 2015, 03:17:50 PMHere are route numbers 20 through 95 in Massachusetts, and whether it would work as a speed limit or not:
95: 85+ is only for straight rural sections, which I-95 is not.
Along the 8-lane stretch of I-95 between Exits 50 (US 1) and 57 (MA 113); one could easily set the cruise at 85+ without any real issues, smokey's notwithstanding.
Iowa:
US-20 - not a chance.
IA-25 - doesn't look like it hits any city centers directly, so probably not.
US-30 - maybe once or twice in a western town that it hasn't bypassed yet.
I-35 - hell no.
IA-40 - doesn't exist
IA-45 - doesn't exist
IA-50 - doesn't exist
IA-55 - doesn't exist (man, they're pretty inconsistent with route numbers)
IA-60 - Reasonable. AFAIK, it's an expressway with speed limit 65 for its entire length. Even if it's not, it's very reasonable to do 60 on any given Iowa* 2-lane road.
US-65 - I'm pretty sure 65 is its speed limit between Des Moines and the IA-330 split. Other than that, it's still pretty reasonable.
IA-70 - if you feel ballsy. It's relatively straight, but there might be a few hills here and there and it's only two lanes.
US-75 - again, if you feel ballsy. You could probably get away with it on the freeway/expressway segment.
I-80 - "80 on 80" is a thing.
IA-85 - that part of the state is a bit too hilly to be doing 85 on a country road.
Anything above that is pretty unreasonable in general, and IA-90 and IA-95 don't exist.
Michigan:
M-20 - not the speed limit, but there's probably some sections that can only go that fast
M-25 - maybe in Bay City, or somewhere in a small-town speed-trap
M-30 - likely in some small sections
M-35, M-40, M-45 - very probably
M-50 - maybe
M-55 - most of it
M-60, M-65, M-70 - no way - although M-65 was, back before Nixon's 55
I-75 - I wish
M-80, M-85, M-90, M-95 - again, no way

Indiana
US 40 - In most towns it passes through this is the speed limit.
I-70 - The speed limit is 70 already.
I-80 - could probably handle these speeds.
I-90 - 90 is considered reckless driving in IN.
US 50- 50 would be a bit slow. Most of it is 55 mph.
US 30- Way too slow.
I-65- The speed limit for trucks.

VA 20 has a 25 mph posting in Orange. There are few non-school 20 mph speed zones in Virginia, unlike North Carolina which has many.
VA 35 has 35 mph zones through Courtland and on the outskirts areas of Boykins (25 mph in central Boykins)
VA 40 has a 40 mph zone in Ferrum and likely in other locations given its length
There are no 60 mph zones on US 60 although between Providence Forge and Anderson's Corner would be a reasonable candidate. While Powhatan to Amherst is quite empty, there are only 2 miles of 4-laning on this stretch and there are no 60 mph 2-lane roads in Virginia.

Yep: It's signed for 30 mph in several towns that US 30 goes thru in Camden County where it's 2 lanes wide, including Collingswood, Haddon Twp and Audubon.
QuoteNJ 35 - Hell no, too long and not enough residential areas.
There's several shore towns where portions of 35 are signed for 35, such as Neptune & Toms River.

Elmer and Franklin are two.
QuoteNJ 45 - Between Mantua and Mullica Hill, as well as up until Woodstown, and finally all the way until you reach Salem, yes, but in those areas 45 is a bit too iffy
From Mantua to Mullica Hill, it's signed as 50. But in Mantua itself, along with Woodbury Heights, West Deptford & Westville, portions are signed for 45 mph. And that's just the stretches I travel nearly every day.
QuoteNJ 50 - Maybe. It passes throuh rural areas of Atlantic County, but it may be too fast for the residential areas that it does pass by
The majority of Rt. 50 is signed for 50 mph
QuoteNJ 55 - Definitely. It's a freeway anyway.
It used to be Rt. 55 was signed 55 mph the entire way (ok, except for that mile of 2 lane highway at the southern end). Before the highway opened in Deptford, someone spray painted "Stay Alive, Drive 55" graffiti on the corner of a bridge overpass, which remained there for many years. No idea if they meant the speed limit or the highway. Today, 55 limits only exist for about 1/2 mile in both directions at the southern end, and for about 2 miles on Rt. 55 North as you approach Rt. 42.

20: CT 20 is a partial freeway so I would say no. Although, it's a more rural road past Bradley, 20 MPH is too slow.
25: CT 25 is also a partial freeway. 25 MPH may be acceptable for the rural towns it passes through, but definitely not the whole route.
30: It's a mostly rural and residential road. I guess you could say 30 MPH might be allowed at some small intersections/villages, but not the whole route.
35: CT 35 is mostly residential, so I would say yes.
40: CT 40 is a freeway and 40 is too slow.
45: CT 45 is a rural road, 45 seems about right.
55: CT 55 is also a rural road, but 55 MPH is too fast. CT 55 is mostly a winding road.
70: 70 MPH is way too fast for a residential road.
75: CT 75 is mostly rural/residential.
80: CT 80 is a major E-W arterial in South Central CT, but 80 MPH is too fast since it's mostly residential.
85: CT 85 is a rural road.
95: Besides Bridgeport and New Haven (eventually), I-95 is mostly unchanged since it was originally built. It's mostly all 55-65 MPH.

Speeding was so rampant when the new section of CA-85 opened in 1994, that the joke was drivers thought the route number was also the speed limit. The CHP now does routine enforcement on 85 to try to keep speeds down.

Why'd I miss US 95 x.x
For Georgia:
I-20 - definitely not
GA 20 - could be somewhat plausible in a couple towns, but still slow for a state highway
US 25 - perhaps through some towns
GA 25 - likewise
GA 30 - certainly through towns (Americus, Cordele, etc.)
GA 35 - certainly through towns (Thomasville, Tifton, etc.)
GA 40 - quite plausible, especially for the eastern third of the route
GA 45 - a largely rural route in SW Georgia; might be a bit slow in parts, but certainly doable
GA 50 - yeah, that could work
GA 55 - great!
GA 60 - could work on some stretches south of Dahlonega. Too many mountains north of there.
GA 65 - yep, except for the east end in Pelham (if GA allowed this on 2-lane roads, anyway)
GA 70 - unlikely on what is largely a suburban route
I-75 - south of Macon, sure (if GA's maximum weren't 70, at least)
GA 75 - mountains all the way, so nope
US 80 - the Columbus freeway bypass has too many curves, and nothing else would qualify
GA 80 - rural, but not an expressway and not straight, so no
I-85 - maybe? Pushing it, but not completely insane. (Outside the Atlanta area, obviously.)
GA 90 - much like GA 80, but longer, so another no
I-95 - too much traffic for that
GA 95 - no way
When I first saw this I thought 88 on I 88 on the Illinois Tollway portion - that's reality. But since I cant use it because it's not divisible by 5, How about 55 on I-55?
Old thread, but since Ohio haven't been done yet, I'll contribute
US 20: could work in downtown Cleveland (currently signed at 25), but besides that niche use, nope
OH 25: works for the numerous downtowns it passes through, but otherwise, nope
US 30: it's mostly a freeway or expressway in the state, so nope
US 35: like US 30, mostly freeway, so nope
US 40: works for within urban areas like in Columbus, but in rural areas, too slow
OH 45: mostly a yes
US 50: besides the concurrency with OH 32, yes, 50 could work on 50
OH 55: mostly a rural 2 lane on a relatively straight route, so 55 is perfect, and most likely what is already signed on it
OH 60: no expressway sections, so maximum posted speed is 55. Though there are probably some flat and straight sections where you can drive at 60
OH 65: no expressway sections, so too fast
I-70: maximum posted speed limit in Ohio is 70, which is what is signed on most of I-70
I-75: the speed almost every person drives at on I-75, despite the lower posted speed limit
I-80: too high to be posted, though traffic does flow at 80 in rural sections sometimes
OH 85: :rofl:
I-90: too high, though I wouldn't be surprised if there at least 3 people out there that drives 90 on 90
Since no one did PA years ago...
US 20: too slow, except maybe in Erie
PA 25: is the speed limit in Hegins, and could be the truck speed limit on downhill stretches between there and Newtown, Schuylkill County (not to be confused with the one in Bucks County)
US 30: definitely along the Main Line and in Philly
PA 35: most likely in any of the small villages it travels through
US 40: in more populated areas, yes
PA 45: definitely closer to its termini
PA 50: definitely
PA 55: does not exist currently
PA 60: not since I-376 took over its freeway segments
PA 65: it's a possibility
I-70: once the free segments are reconstructed, definitely (except in Breezewood); Turnpike segment is posted at 70
PA 75: too fast
I-80: many travel this fast anyway, so why not?
PA 85: nope
I-90: some travel this fast, but probably not the best idea, especially during lake effect
I-95: too fast (although some do it anyway)
PA 100: too fast mph, could work in many places kph

CA 35 (Skyline Boulevard) would be rather slow but close to reasonable.
I-40 - way too slow
CA 45 - also slow, but closer to tolerable
US 50 - a bit slow for the freeway in Sacramento, a bit fast for some of the mountainous stretches in El Dorado County.
CA 55 (Costa Mesa Freeway) - close to normal
CA 60 (Pomona Freeway) - close to normal
CA 65 - close to normal
CA 70 - too fast for much of this route
CA 75 - pushing it
I-80 - close to actual speeds during low-traffic periods; too fast for Donner pass
CA 85 - pushing it
Good one.
Utah:
5: does not exist
SR 10: too slow
I-15: haha
SR 20: does not pass through any towns, none of the mountain segments are that bad
SR 25: see 20
SR 30: section through Logan
SR 35: segments through Francis and maybe Hanna and/or Tabiona
US 40: several sections in/near towns including Heber, Duchesne, Roosevelt, Vernal
SR 45: would be reasonable around Naples, but the actual limits skip 45
US 50: edges of several towns it passes through, actually posted 50 near Scipio and Salina
SR 55: too fast - business loop with quite a bit of activity
SR 60: too fast - windy suburban/exurban road
SR 65: could work east of Big Mountain Pass, but I think the actual road is posted 55 or 60 instead thanks to mountains
I-70: a couple of mountain sections
SR 75: too fast - exurban surface connector road
I-80: over half its route in Utah
SR 85: too fast - suburban/exurban expressway with a 65mph limit ... but that doesn't stop some people
SR 90+: no
Pennsylvania:
5 - too slow
10 - too slow
15 - too slow
20 - too slow
25 - reasonable in some of the towns like Millersburg
30 - reasonable in towns like Gettysburg
35 - reasonable in McAlisterville
40 - reasonable in Chalkhill (but a little slow), quite reasonable in Brownsville
45 - exists in my town! Reasonable in many places through central PA
50 - curvy, somewhat developed, reasonable on much of it.
55 - doesn't exist.
60 - on old Route 60 (now I-376) it would be fine. As it is, too fast.
65 - some of it is four lane divided, rural, reasonable
70 - reasonable on most of I-70 in PA
75 - super rural, through the middle of nowhere. Reasonable.
80 - bet your bottom dollar, I-80 should be 80mph in PA.
85 - unfortunately, too fast.
90 - I guess they could get away with it in the most rural portions... 90 is certainly a fine speed, whether it's a reasonable limit is subjective.
95 - no.

Michigan:
M-20 - not the speed limit, but there's probably some sections that can only go that fast
M-25 - maybe in Bay City, or somewhere in a small-town speed-trap
M-30 - likely in some small sections
M-35, M-40, M-45 - very probably
M-50 - maybe
M-55 - most of it
M-60, M-65, M-70 - no way - although M-65 was, back before Nixon's 55
I-75 - I wish
M-80, M-85, M-90, M-95 - again, no way
Since posting, significant sections of I-75 have been posted at 75 mph since 2017.

Iowa:
US-20 - not a chance.
IA-25 - doesn't look like it hits any city centers directly, so probably not.
US-30 - maybe once or twice in a western town that it hasn't bypassed yet.
I-35 - hell no.
IA-40 - doesn't exist
IA-45 - doesn't exist
IA-50 - doesn't exist
IA-55 - doesn't exist (man, they're pretty inconsistent with route numbers)
IA-60 - Reasonable. AFAIK, it's an expressway with speed limit 65 for its entire length. Even if it's not, it's very reasonable to do 60 on any given Iowa* 2-lane road.
US-65 - I'm pretty sure 65 is its speed limit between Des Moines and the IA-330 split. Other than that, it's still pretty reasonable.
IA-70 - if you feel ballsy. It's relatively straight, but there might be a few hills here and there and it's only two lanes.
US-75 - again, if you feel ballsy. You could probably get away with it on the freeway/expressway segment.
I-80 - "80 on 80" is a thing.
IA-85 - that part of the state is a bit too hilly to be doing 85 on a country road.
Anything above that is pretty unreasonable in general, and IA-90 and IA-95 don't exist.
25 is the speed limit for IA 25 in Guthrie Center, where there is a 4 way stop at IA 44. I imagine other towns on the route have a 25 mph limit.

I-55- yes in major cities like Chicago and STL, but no outside of those areas
IL 60- perfect for a speed limit increase on two-lane roads, but it's going to be a no since it runs through Lake County
IL 65- none

US 50? I'm guessing it's a bit low considering 2 lane rural roads are generally signed at 55 already.
Not sure if I should nitpick on US 60 for IL, considering it's like a mile long in the state.

Indiana
US 40 - In most towns it passes through this is the speed limit.
I-70 - The speed limit is 70 already.
I-80 - could probably handle these speeds.
I-90 - 90 is considered reckless driving in IN.
US 50- 50 would be a bit slow. Most of it is 55 mph.
US 30- Way too slow.
I-65- The speed limit for trucks.
IN 25 has a speed limit of 25 in Logansport and possibly other places
US 35 has a speed limit of 35 in LaPorte and likely many other places
IN 45 has a speed limit of 45 in Bloomington and likely other places
US 50 goes from 55->45 on both ends of Seymour so 50 could be a speed limit there
IN 55 has the vast majority at 55
IN 60 is not four lanes so not eligible to be 60 in Indiana

Washington:
I-5: Traffic jams will do it (or an opening on the Interstate Bridge)
SR 10: Not necessary, given how remote it is
SR 15: Does not exist
SR 20: Probable for some of the small town centers it passes through, or the approaches to the ferry queues
SR 25: Doesn't pass through any town centers, but the speed limit would be appropriate for the Candian border.
SR 30: No longer exists
SR 35: The new Hood River Bridge is expected to have a 35 mph speed limit, so this is perfect
SR 40/45/50/55/60/65/70/75/80/85: Does not exist
I-90: Possible in some stretches, but not recommended
North Carolina:
NC 5: Much too slow for something that rural.
NC 10: Rather slow, though maybe if you're stuck behind a truck climbing the mountains? Better for some of the more-decayed parts of Old NC 10 from when it used to be the cross-state highway.
US 15: Sure, when you're stuck in traffic around Chapel Hill.
NC 20: Maybe in the heart of some small towns, I guess.
NC 25: Doesn't exist
NC 30: Still on the slow side. Greenville hasn't gotten out that far yet.
NC 35: Okay, when you're in a small town.
I-40: This'd be an improvement at rush hour!
NC 45: Sounds good.
NC 50: Sounds great on the eastern part; sounds much too fast around Raleigh.
NC 55: Perfect for some of the new bypasses.
NC 60: Much too fast for that mountain road.
NC 65: Suburban, but still too fast.
US 70: Perfect for the freeway parts.
NC 75: Nope, it's too suburban.
NC 80: Ouch goes the mountain road.
I-85: Great!
NC 90: Says Wikipedia, "It is one of the few highways in the state with an unpaved portion."

US 45 can and does have some 45 MPH Zones outside of Chicagoland, as it makes its way south thru eastern Central and Southern Illinois, generally along the I-57/I-24 Corridor towards Metropolis and Brookport and the Ohio River
US 50 has already been addressed
US 60: That would upset Cairo/Alexander County Police/ISP District 22, and probably be a bit high, especially for those 2 older bridges. US 60 in Illinois is basically the Illinois side of the Mississippi and Ohio River Bridges, and a 3-way intersection, with US 51 at the southern tip of the state, where US 51 NB/US 60/62 WB is Stop-sign controlled
I-70: I think 70 MPH is a bit slow for most of the route in IL, but that is a personal opinion
IL 100: :bigass:
The Sum/Total for the I-39/US 51 Duplex of 90 is completely appropriate for most of that Freeway! When on the Jane Addams Tollway and it is the the US 51/I-39/90 Triplex east of Rockford, the Sum/Total of 180 is probably a bit high. Southeast of Rockford, the Sum/Total of the US 20/51/I-39 Triplex of 110 MPH is high, also. 110 km/h could work, tho (SkyPesos pointed that out for IL 110/CKC also). Interestingly, the Sum/Total of the US 51/I-55/74 Triplex around Bloomington/Normal, IL is also 180, but again, a bit too high
Parts of IL 110/CKC would be doable at 110 MPH, but still would probably be signed a bit high. Especially the parts along I-88, I-74, and I-172 *could maybe* get away with it. The OP does put a limit on anything above 100, anyway

110 km/h is about 69 MPH - that would even be fine on much of the 110/336 and 110/US 67 Expressway duplexes thru Western IL, tbh

The ludicrous congestion and poor roadway conditions on I-270 means that you're lucky to go 27, much less 270.
I'd add CO 58, which would be about the average of the posted 65 mph and 55 mph sections.
Where are you going to see a speed limit 58 or 76?

Ironically, Denver's I-270 is the only I-270 that I haven't been on yet, and it's the shortest one of the 270 quartet. Granted I lived in both Cbus and StL for a bit and DC's I-270 is the main entrance into the metro area from the Midwest.
Since this is about speed limits, could be possible to go 270 km/h on 270 if someone wants to dream a high speed rail line that parallels one of them, since 270 km/h is a standard speed for HSR :)

No problem. I-95 isn't of much importance for most North Carolinians anyhow. But we do get frequent traffic reports about I-95 shutdowns here in the Triangle. Sometimes I think the traffic reporters are trying to remind folks on I-40 that life could be worse.
Here's a section of US30 in Illinois I drive on all the time, with the speed limit sign and route marker in the same shot.
https://goo.gl/maps/2w66yjAdNJXu48mC9
IL-35 somehow has every speed limit from 30 to 50 EXCEPT 35 along its 2-mile route. https://goo.gl/maps/gN9G2CKzLron2EaN6
Here's a 40-mph section of IL-40 in Peoria. https://goo.gl/maps/unftYnQNbqfWnVdr9
Here's a 40-mph section of US40 in Vandalia. https://goo.gl/maps/aRd7uzuKrHzPwEQYA
45mph is the second most common speed limit on IDOT roads, so a 45-mph section of US45 wasn't hard to find: https://goo.gl/maps/cnEYVxefp9jjsSkR6
Here's a 50-mph section of US50 in Lebanon. https://goo.gl/maps/W6XQdurGY19AHvFp7
I-55 is 55mph in most of Chicagoland from Bolingbrook east, so that's too easy.
I-70 is 70mph in most rural areas, so that's also too easy. https://goo.gl/maps/ZFZbxHtkRa5pGtoV7

Whoops, forgot about US 50! I would say it's too slow for some sections, but there are some spots that are perfect for US 50.
Found one!

Funny, I almost posted that one instead of the one I chose.
Just a couple from Montana:
US 2 - You really don't want to walk along much of it.
I-15 - That would take forever to get anywhere. Please no.
US 87 - May or may not have done that and faster on the section between Great Falls and Havre. Straight, flat, and boring.
US 89 - Some straight, flat sections where that'd be fine. The mountains, not so much.
I-90 - Most of it outside of the mountains would be fine, as people generally do 80-85 on it anyways.
I-94 - Yes please. All of it.
MT 200 - Anyone have a Hellcat Challenger I can borrow to "test"?
US 212 - You really don't want to try that on Beartooth Pass, unless you missed a decimal point between 21 and 2.
Best fits for Texas:
20: PR-20 - Very appropriate.
25: PR-25 - Also very appropriate.
30: PR-30 - A little fast, but relatively appropriate.
35: SH-35 - Too slow for most of it, but the speed limit for the route is 35 in the city center sections.
40: PR-40 - Looks very appropriate for most of it.
45: FM-45 - A little slow, as the road is straight, narrow, and nearly abandoned, but the shoulders are basically nonexistent, so it's alright.
50: SH-50 - Would be about right in most parts of the country, but in Texas this two-lane road has a limit of 70.
55: FM-55 - Literally perfect.
60: SH-60 - Also literally perfect.
65: SH-65 - Again, literally perfect.
70: US-70 - Perfect for most of it.
75: US-75 - Perfect north of McKinney.
80: US 80 - Maybe on the rural sections between Terrell and Hawkins?
85: SH-85 - A bit of a stretch for a two-lane road.
90: US 90 - Possibly feasible between Marfa and Van Horn.

Old thread, but since Ohio haven't been done yet, I'll contribute
US 20: could work in downtown Cleveland (currently signed at 25), but besides that niche use, nope
OH 25: works for the numerous downtowns it passes through, but otherwise, nope
US 30: it's mostly a freeway or expressway in the state, so nope
US 35: like US 30, mostly freeway, so nope
US 40: works for within urban areas like in Columbus, but in rural areas, too slow
OH 45: mostly a yes
US 50: besides the concurrency with OH 32, yes, 50 could work on 50
OH 55: mostly a rural 2 lane on a relatively straight route, so 55 is perfect, and most likely what is already signed on it
OH 60: no expressway sections, so maximum posted speed is 55. Though there are probably some flat and straight sections where you can drive at 60
OH 65: no expressway sections, so too fast
I-70: maximum posted speed limit in Ohio is 70, which is what is signed on most of I-70
I-75: the speed almost every person drives at on I-75, despite the lower posted speed limit
I-80: too high to be posted, though traffic does flow at 80 in rural sections sometimes
OH 85: :rofl:
I-90: too high, though I wouldn't be surprised if there at least 3 people out there that drives 90 on 90
Come on man, you didn't consider the complete route on a couple of these...
US 35 west of Dayton is 35 in New Lebanon, West Alexandria and Eaton.
US 50 is signed for 50 between Terrace Park and Mariemont and through Addyston and west much of the way to Indiana
I'm completely surprised in taking a couple sample looks I am not seeing any parts of US 40 signed for 40 although I it seams like I've seen it, unless they've upped the speeds which at US 40 / I-70 interchange east of Springfield they have.

I thought I've seen a couple of 40 mph on US 40, but I checked it and some other roads in the Columbus area, and it seems like 40 mph is rare. 35 mph is very common, and US 40 goes up from 35 to 50 at the eastern I-270 interchange. But lots of the 35 mph sections of US 40 can be bumped up to 40 mph, like this one (https://www.google.com/maps/@39.9556745,-82.7817062,3a,75y,78.13h,80.7t/data=!3m6!1e1!3m4!1slpCxy6Vv2oVV1tVtjpzgXQ!2e0!7i16384!8i8192)

That last example could be 55 with no problem.

Thanks. I forgot those even existed.
TX-130: 85mph (approx. equal to 130 km/h)
US-59 in Houston downtown: 60 mph (59 and 60 are really close)
I-10/20 in west TX: 80 mph (it was US-80)
I-95 along the Jersey Turnpike could definitely handle 95 mph, as well as sections in Florida and near the NC/SC border.
I-80 in NJ could reasonably be 80 mph
87 mph on I-87? Fine with me. But that's not a 5, so 90 mph on I-90 will have to do.

Easily. One of the widest roads ever with 10+ mile straight sections.

What about your proposal for a nation-wide (or was it world-wide?) 37 mph limit on non-limited access highways? Sadly, there is no US 37, but plenty of state route 37s. Would those qualify in the MMM universe? :poke:
AL 5 - too slow
AL 10 - same
AL 15 - too slow, but in-town route
AL 20 - very slow
AL 25 - slow
AL 30 - slow
AL 35 - makes sense in some towns in goes through
AL 40 - slow but not unheard of in the uphill portions
US 45 - slower, but makes sense in some towns
AL 50 - ok, could be higher
AL 55 - ok
AL 60 - ok
AL 65 - a bit too fast for most sections
I-65 - a bit too slow for some sections, but doable
AL 70 - too fast for its length
AL 75 - a little too fast, unless it's a completely empty road
US 80 - maybe in a few empty four-lane sections, not likely
AL 85 - too fast for a two-lane road
I-85 - possible but not a great idea
US 90 - not happening
AL 95 - no
AL 100 - small intra-city route, bad idea even if in km/h
I'll try Maine since no one has done it yet.
ME 5 - No unless the tourists are coming home on a summer Sunday
ME 10 - Nope
ME 15 - Definitely not
ME 25 - Ditto as the others
ME 35 - Absolutely. In fact it's posted at 35 in Kennebunk.
ME 85 - Too short
I-95 - Only north of Bangor
A couple more to add to the CT list:
5: Way too slow
10: Given the traffic sometimes on Queen St in Southington, you would think that was indeed the limit on that stretch. But in reality, too slow.
15: Maybe if you added a 1 before it you'd have one that was appropriate (especially for David Letterman).
84 for I-84 works except through Danbury, Waterbury, and the Hartfords. And 91 works for I-91 between the New Haven city line and I-691; and between Windsor and the MA line (and to the Forest Park curve a couple miles north).
New York:
15 - Absolutely not
20 - Maybe in the circle in Avon (https://www.google.com/maps/@42.9117469,-77.7442364,3a,18.1y,335.54h,88.91t/data=!3m6!1e1!3m4!1s1fYUO6T8t7For8HWpfi28w!2e0!7i16384!8i8192), but anywhere else would be silly at best.

60 - Most of the 55mph sections of NY-60 could easily handle 60mph (not possible under current NYS law, but certainly possible in states that would allow it)
65 - Nowhere on NY-65 is really capable of a 65mph speed limit (under any circumstances, since obviously it isn't possible under current NYS law), though there are a few small straightaways where it could be done safely.
70 - No chance of NY-70 ever being posted at 70
75 - The southern portion of NY-75 may be fairly straight, but it is nowhere near flat enough to even consider something silly like this.
80 - Maybe in km/h on NY-80, since there are plenty of not-so-straight sections of 55mph
85 - Some people might do 85mph on the freeway section, but that would be pretty reckless
90 - I would support it on I-90, but politicians sure won't. Conversely, NY-90 has some sections safe to drive at 90 km/h.
95 - The original speed limit on the New England Thruway was 60 mph, which is roughly 95 km/h.
100 - I have driven 100 km/h on NY-100 from Millwood to Hawthorne (thanks to rush hour traffic).
105 - Absolutely not
110 - Absolutely not
115 - Absolutely not
120 - Absolutely not
125 - Absolutely not
130 - Absolutely not
135 - It's a freeway on Long Island, so of course people go 135 km/h :biggrin:
One more for California:
CA-25: quite slow for the current route, but 25 MPH may have been the posted limit when it was routed through downtown Hollister.
(CA-30 has been replaced by CA-210, but its original surface street routing had residential sections that could have been posted at 30 MPH.)
Colorado:
CO 5 - Only in MMM's world around those dangerous curves
CO 10 - dear god no
CO 15 - Too straight
I-25 - No
CO 30 - If Aurora grows larger, probably
CO 35 - Absolutely
CO 40 - Sure
US 40 - In the mountains and Denver, makes sense
CO 45 - Posted in its majority
US 50 - yes
CO 55 - Definitely
CO 60 - Much better than it currently is in Milliken
CO 65 - Too curvy

Some of you guys are being a bit too extreme with some of these ideas. posting 90-95 on any freeway besides like a few stretches out west is way too fast. Like the NJ Turnpike should not be speed limit 95.

It could be 120. It's one of the best roads in the northeast. Out west should be unlimited. 90-95 mph is a reasonable safe crusing speed on the Jersey Turnpike.
Speed limits have rarely been raised by more than 5-10 mph at a time. It's a complete fantasy to expect a route will suddenly go from 65 to 90 just because it's straight enough. Unless some new advances in transportation safety and technology makes huge leaps in dramatically lowering road accidents, injuries, and fatalities, you will not see speed limits get increased by large leaps without some sort of public backlash.
Enough already.
Quote from: MultiMillionMiler on February 06, 2023, 09:00:08 PM
Karens backlashing shouldn't dictate road rules. After driving that road dozens of times I can confirm traffic flow averages around 90 mph when traffic is light. No major advances in driving technology need to be made, just so you don't lose control on a road that's straight for 120 miles.
Except most passenger car accidents at 100+ mph are not survivable. We were on a downtrend on fatalities and then it all bounced back right around the time more than 50% of the population got a cellphone/smartphone. And you really think 120mph drivers should be mixing it up with drivers who are legitimately interested in only going 65-75?
Dude, just buy some track time and see if you don't almost shit yourself at least once.

PA-50: some of the hillier, twistier portions would be alright at 50
PA-55: doesn't exist
PA-60: no, it's in Pittsburgh, but it used to be a freeway where 60 would be very reasonable
PA-65: some bits near the North Shore would be fine at 65
I-70: lots of it already is (on the Turnpike)
PA-75: I've definitely done 75 on this road, there's a lot of wide open empty stretches in south-central PA
I-80: most of it please and thank you

At times up our way, yes. I have been in life-changing traffic through the construction. I only go to Denver maybe once a month, so when I do, I take 66.
85 on 85 could work north of Nunn. The next anything remotely resembling anything, is Rockport, which, the last time I was by it, was a broken soda machine in front of an abandoned bar.
For 90 and above, I'll go into the fantasy zone.

AR 25 I think has a 25 MPH speed limit somewhere
I-30 - no chance lol
AR 35 has multiple 35 MPH speed limit sections
I-40 - literally no chance
AR 45 at 45 MPH probably exists
AR 50 at 50 MPH may exist but I think almost the entire route is signed at 55 MPH instead
I-55 I think has a 55 MPH speed limit in West Memphis but I could be wrong
AR 60 - Does not exist (I don't think)
US 65 has multiple sections at 65 MPH, south of Pine Bluff and north of Harrison and the concurrencies with I-40
US 70 (I think) has a 70 MPH section along the Hot Springs bypass IIRC
I believe that Chicago Police have already written numerous speeding tickets on IL 50 (Cicero Ave). Illinois route number shields look a LOT like USA MUTCD speed limit signs.

Anyone who agrees with me that Illinois should spice up the design of their state highway marker is all right by me!!
If it wasn't for truck traffic, I-90 could absolutely be 90 mph. (This applies to most of the route, but I'm thinking specifically about the NYS Thruway portion).

Depending on the time of day, you can go 75 on US 75 from Woodall north. Once you cross the Grayson County line, that is the actual posted speed. In the metro it's posted as 70.
When I was I n high school this girl I was dating got on I-35 in KC and started driving super slow. I asked her why and she said "Speed limit is 35" :-D

Was she perchance drunk at the time?
Seeing this topic I have to post this joke, hoping it's not inappropriate here:
A Connecticut state trooper pulls over a car on the Merritt Parkway for going too slow. He finds it occupied by four nuns and asks the driver, "Why were you driving so slowly?"
"I saw the signs saying 15, the speed limit."
"No, Sister, 15 is the route number. The speed limit is 55 mph, with a minimum of 40."
Then one of the passengers says, "Sister Beatrice, that explains why we almost got into all those accidents when we were on I-95!"
Doesn't look like anyone's done WI yet
20 - no
25 - almost entirely no
30 - no. WI-30 is a freeway.
40 - no
45 - I'm sure there are a few 45 MPH sections of US-45, but overall, no
50 - wouldn't be the end of the world, but would definitely feel slow, especially since it's almost all 4-lane divided. It gets purple.
55 - that's what it is, outside of the handful of towns it passes through.
60 - would work fine in the rural areas that comprise the vast majority of this route. Though the stretch from I-39/90/94 to Spring Green is better off at 55 due to curves.
65 - too fast
70 - ehhh . . . no two lane road should ever be posted this fast, but if I had to choose one in WI to be posted at 70, WI-70 is a candidate.
75 - no
80 - no
85 - no
90 - sounds nice in theory, but would be chaos. Way too much truck traffic (and just traffic in general) on I-90 in WI for 90 MPH to be anything but a disaster.
95 - yeah sure it'll be fine, just trust me bro
100 - 100 through the busiest surface intersection in the state? What could go wrong?
I've mentioned this in other threads, but I wonder how many speeding tickets Chicago Police have written over the years on Cicero Av (IL 50), especially since Illinois state route shields look so much like MUTCD speed limit signs.
:hmmm:

I think it's safe to say that none of Alaska's apply. Maaaaaybe AK10 in the winter.
I'm going to make 2 lists for Ireland: one in km/h and one in mph.
km/h
N10, N20, N30 -> too slow
N40 -> could possibly work for some sliproads, otherwise too slow.
M50 -> would work for some sliproads and the section by the toll but otherwise too slow.
N60 -> may work when passing through towns but otherwise a bit too slow.
N70 -> would be a bit slow in places but tolerable
N80 -> slightly slower than desirable but still suitable
90, 100 -> roads do not exist
R110, R120 etc. -> too fast (low numbered R-roads are located in Dublin City, so no chance of ever doing 120km/h or whatever there)
mph
N10, N15, N20, N25 -> too slow
N30 -> may have been suitable for the sections through town centres, but these have since been bypassed.
35 -> road does not exist
N40 -> may work on some sliproads, but otherwise rather slow.
45 -> road also does not exist
M50 -> would be suitable, albeit slightly slow on the quieter southern portion
N55, N60 -> suitable outside of towns
N65 -> overly fast in places but not terrible
N70 -> may work in places, but too fast in others
N75 -> high, but more capable of handling fast traffic than the N70
N80, N85 -> getting too fast at this point
I-75 in Florida?
FL 60 is 60 mph across Old Tampa Bay. :-D
Nevada has only a couple state routes in the two digits, and both end in 8, so those don't qualify. Looking at the qualifying Interstates and US routes:
I-15: Not as a posted limit, but that's the actual speed at times through Vegas, and approaching the California state line on weekends.
US 50: Yes, 50 is posted near some developed areas, locally on the 4-lane segment from Glenbrook over Spooner Summit to I-580/US 395.
I-80: Yes, 80 is the posted limit for a number of segments.
US 95: We're not going to post a 95 mph limit any time soon, but it would be feasible, particularly on the 4-lane divided highway from the edge of the developed area of the Las Vegas Valley up to Mercury, and also from I-11 at Boulder City south to the SR 163 junction. There are even a few two-lane segments that could be argued for, notably from Tonopah west to Coaldale Junction.

I-75 - I wish
This thread has been resurrected from so far in the past, that my wish has come true, at least for the northern 60% of the route.
