I know in the road world there are many records just like in sports, you can break it down in many ways. I here decided to break it down to longest roads in specific areas of my state, county, region, etc. Here is my list of some record breakers in the part of the nation I live in.
State of Florida
Longest route designation of any kind: US 98 @ 671 Miles
Longest Interstate or Continuous freeway: I-75 @ 471 Miles
Longest State Route (Unsigned) SR 5
Longest State Route (Signed)- SR 20
Longest Divided Highway-US 27.
Longest Gap on Freeway Between Exits in Florida- Florida's Turnpike @ 47 Miles between St. Cloud and Yeehaw Junction
Orange County, FL
Longest Named and Numbered Road- Colonial Drive (SR 50)
These are all I have to start with for now, but as I come up with more I will add.
US 1
I amended US 19 and US 1 as US 27 blows that two out of the water. From Miami Springs to Williston, and from Perry to Georgia with the whole 96 miles of US 27 ALT are divided with small undivided center turn lanes in cities and towns.

Longest Divided Highway-US 1
There are short pieces with center turn lanes.

State of Florida
...Longest State Route (Unsigned) SR 5
I'm sure SR 10 is longer, and mostly unsigned (US 90's secret number).
There's portions of FL 5 that are signed as a standalone state route (i.e. not part of any US Route), and US 1 becomes "SR 805".

Longest Divided Highway-US 1
Longest Divided Highway in Transit- US 19 It is almost completely divided within its Florida run.
what is this distinction?
US 19, with the exception of the cities along the way is pretty much divided from its southern terminus into Georgia.
US 1, has a long two lane stretch in the Lower Keys, so you cannot really say that most of it is divided. Like NE 2 mentioned there are plenty of places along US 1 with center turn lanes and most of that is in South Florida.
Actually I forgot about US 27. That is divided much longer than US 19 and US 1. I need to amend that one.
Quote from: roadman65 on July 15, 2013, 01:10:07 PM
Longest Interstate or Continuous freeway: I-75 @ 471 Miles
Make that 476 miles, you forgot that the freeway continues south/east along SR 924.
On that note, how would TOTSO situations be handled? I would consider the continuous freeway in question to continue along I-595 towards Ft. Lauderdale, not along I-75 toward Hialeah. That would make the mileage a few miles shorter, but it'd still be the longest in the state.
Longest motorway-like road in the world: I-90 at 3,101 miles (4,990 kilometers).
Longest motorway-like road outside the U.S.: Chinese G30 at 2,636 miles (4,243 kilometers). I believe it was completed last year, but I doubt about a section in central Gansu.

I wouldn't consider it a TOTSO. Here's why:
From I-75 "east" to I-75 south: 3-lane ramp
From I-75 north to I-75 "west": 3-lane ramp
From I-75 "east" to I-595 east: 2 thru lanes
From I-595 west to I-75 "west": 2 thru lanes
Since I-75 is effectively 3 lanes in each direction (save the portion approaching the I-595/FL 869 interchanges), and continues with one seamless motion, it's more of a kink in the road than a turn-off-to-stay-on situation.
I-55 north in Memphis, headed out to West Memphis...that's another story.
speaking of longest segments of many lanes in each direction... I think we once had a discussion and discovered that I-5 between San Ysidro and the LA county line is the longest freeway which is 4 lanes or more in each direction. it drops to 3 and then down to 2 through the East LA interchange.

US 460 is not continuously multilane. In Crewe, VA it is just one lane per direction with a center turn lane. There is also another segment like this west of VA 112 in Salem but was being widened last time I was there. Additionally, there is a segment like this climbing Christianburg Mountain just east of I-81 exit 118. Finally, there is a true 2-lane segment from central Salem east to nearly VA 419.
My guess is the longest continuous multilane non-interstate route in Virginia is US 58 from west of Stuart to Bowers Hill, nearly 250 miles.
Historically, the longest route in Virginia was VA 10 prior to 1933. The 1926 Official map put its distance at 569 miles from Cumberland Gap to Virginia Beach via Roanoke, Lynchburg, and Petersburg.
The exit gap you cite is 9.24 miles per the 2012 traffic log. I-81 between Exit 118 US 11-460 and Exit 128 SR 603 is 9.73 miles.

Maryland
Longest Interstate highway - I-95 at about 109+ miles
Longest distance between interchanges - I-68 in Garrett County between exits 4 and 14 at about 9.65 miles (though there is a rest area/welcome center on the eastbound side) - alternatively, I-95 (JFK Highway) in Cecil County between exits 100 and 109 at about 8.72 miles has no rest area or welcome center
Longest non-Interstate highway with full access control - Md. 295 (Baltimore-Washington Parkway) at about 29.5 miles (about 18.6 miles is National Park Service maintenance, about 10.3 miles is state maintenance, and less than 1 mile is Baltimore City maintenance)

Arizona is rather different, with many routes being mileposted as spurs of others, and mileage continuing from the split. But US 89(A) isn't even numbered strangely - it really was that many miles from Nogales.
http://www.azdot.gov/mpd/gis/maps/pdf/mps.pdf
Strangely, SR 80 (and spurs, including SR 186) seems to be numbered via SR 84 from Gila Bend to Tucson, not via US 80 and Phoenix.

Yeah, I think I might get it but I'm not at all sure.
It seems like east-west and south-north routes are essentially being tied to specific milepoint numbers when certain county lines are crossed. So I guess this means US-67 jumps several milepost numbers ahead. I think...

I've looked at this for two minutes and still don't understand it. Seems needlessly confusing to me.
It is somewhat complicated. They're called reference markers, not mile markers, because they don't represent actual mileage (except when within a single county when there has been no rerouting). For US 67, measure the distance from the given latitude (the latitude of the given point) directly south to the northernmost point of the highway (where it enters the state). Remember that the beginning point is 10, not 0(a highways starting at the state line at the north end of the Panhandle has an initial number of 10). A marker is placed every two miles, with the number (almost always even) increasing by two. They are generally placed on alternating sides of the highway, with one on each side every four miles (the number is displayed on both sides of the sign post and can be seen from both directions during daylight).
An additional complication is that the measurement starts again at each county line (unless the marker falls close to that line, in which case the marker will be set accurately according to mileage but not directly on the county line). If the last marker from the north is 486, and it's one-half mile to the county line, the next marker, 488, will be directly on the county line. This results in numbers that grow faster than mileage.
Also, once the marker is placed, it is not moved. If a bypass is built, the original markers downstream from it are not moved, and no longer represent accurate mileage from the markers upstream from the bypass. The markers along the bypass are not placed every two miles, but are spaced evenly to fill the gap in the numbers. Markers along the bypass that are not spaced at 2 mile intervals have an A used as a suffix (such as 486A while the marker along the business route retains the number 486).
To see the placements and numbers of markers, go to the Statewide Planning Map, and select Markers near the bottom of the list. Note that Interstate highways have actual mile markers accurately placed every mile, but not all of them are shown on the map. Also, markers are not shown on the map along business routes, although in my experience they are left in place.

No and this one is only as it is an old sign (you wouldn't go that way anyway. Plus the fractions with a distance way above the rather small recommended distance).
The furthest distance on a modern sign in the UK is the A30 leaving Exeter with London at 166 (https://maps.google.com/?ll=50.730479,-3.450866&spn=0.016434,0.042272&t=m&z=15&layer=c&cbll=50.730507,-3.450734&panoid=yShs6UWdteCFBgLlkFiSNQ&cbp=12,73.64,,0,9.05). The only other places signed with 100 miles distances in England and Wales are Harwich and Felixstowe (https://maps.google.com/?ll=52.404854,-1.17455&spn=0.015945,0.042272&t=m&z=15&layer=c&cbll=52.404683,-1.174344&panoid=jFlTHdnszcccEtsstdheLQ&cbp=12,136.51,,0,21.02). Scotland has lots as there are long distances with nothing and Dublin is signed at over 100 at various places in western Northern Ireland.
Places might be signed, but mileages aren't always given (see, for instance this one (https://maps.google.com/?ll=53.843362,-1.342134&spn=0.03084,0.084543&t=m&z=14&layer=c&cbll=53.843111,-1.342011&panoid=ujN3tgqu4Vfdup1Nh0wIeg&cbp=12,165.2,,0,10.96) which would be 200ish to London that way and 190ish the more direct route down the A1, and I'm almost certain that that is the furthest away London appears on a sign*). Maybe there's a milestone on the Great North Road in Yorkshire that gives a slightly higher figure to London than this 221 (http://www.geograph.org.uk/photo/1802509), but this the highest I can find - the London figure, however, is little more than a chainage marker, which means that we ought to include this 504.5 (https://maps.google.com/?ll=54.99341,-3.047462&spn=0.003724,0.010568&t=m&z=17&layer=c&cbll=54.993343,-3.047325&panoid=NBGjYm5M8NsknIepe3gJTQ&cbp=12,78.43,,2,10.07) marker - the highest in the land. This 504.4 (https://maps.google.com/?ll=54.992998,-3.046657&spn=0.003724,0.010568&t=m&z=17&layer=c&cbll=54.992856,-3.046397&panoid=dTwxy_hxAhyseGqOuZ6BFw&cbp=12,127.04,,0,2.6) is the highest number on a sign that isn't a road number (it is km from London via the M1).
*And only because at the next junction they want to divert you off of the busy and congested A1 section between Doncaster and Darrington, and the dire A1(M)/M18 junction, and onto the busy and congested M1 that goes the long way around via Leeds and Sheffield.
Edit: completely forgot milestones in Cornwall: London 245 (http://www.geograph.org.uk/photo/1527003).
Edit again: this 167 to London RCS on the M5 at Taunton (https://maps.google.com/?ll=50.97394,-3.171101&spn=0.032914,0.084543&t=m&z=14&layer=c&cbll=50.973949,-3.170876&panoid=Jc8BN6BsCzMbG2BmN1SbGQ&cbp=12,78.67,,0,16.9) just beats the Exeter one (despite being some way closer as the crow flies) and this sign (https://maps.google.com/?ll=50.06633,-5.714623&spn=0.002097,0.005284&t=m&z=18&layer=c&cbll=50.06626,-5.714701&panoid=ITTyrQvE-C5-k9eSIc-WWg&cbp=12,326.63,,2,1.71), which is better than its opposite (http://www.geograph.org.uk/photo/931325)!
awesome stuff; thank you for hunting all those down!

Long Island
Longest interstate: I-495 (the only one)
I-495 might be the longest, but 278, 678, and 295 are all in Long Island as well. Kings and Queens County do count since they are on the island.

Shortest collapsed/destroyed bridge: I-5 Skagit River Bridge - 1,112 feet
incorrect. I once built a bridge across a small rivulet of water using two rocks and a stick. it immediately collapsed because I didn't do a very good job of it. it was maybe 6 inches long.
Ah, but Jake, was your stick bridge in the state of Washington?
In all seriousness, 1,112 feet is the length of the entire bridge. Only a single span measuring 160 feet collapsed. But I'd bet you could find a still smaller bridge that has been abandoned to collapse (my hunch says on the Olympic Peninsula, but don't ask me why). Perhaps not on the state highway system though?

Or, in other words: I did not research any other bridge collapses before posting. :bigass:
Here are some categories that interest me:
Longest stretch of highway across a single county: in Texas, I-10 across Pecos County, 100 miles
Longest highway entirely in one county: in Texas, SH 54 in Culberson County, 55 miles
Longest stretch of highway between two consecutive highway intersections: in Texas, SH 118 between US 67/90 and FM 170, 78 miles
Longest stretch of Interstate between two consecutive Interstate intersections (in one state): in Texas, I-20 between I-10 and I-30, 421 miles
Longest stretch of Interstate between two consecutive Interstate intersections regardless of state lines: Anyone?
For the latter, there is almost 500 miles between I-5's junctions with I-80 (Sacramento) and I-84 (Portland). But if you include auxiliary connections, then it's much less, as there is a (one-way) connection with I-505, I-105 in Eugene and I-205 in Portland.

actually, yes. in Bellingham down by the beach.

Hmm... I believe it's I-80 between I-580 in Reno and I-215 in Salt Lake City. 512 miles. That's what the very outdated Roadfan FAQ (http://roadfan.com/mtrfaq.html#a6101) says. Runner-up would probably be I-70 between I-15 in Utah and I-76 in Denver, 501 miles.
But if we're only counting
signed Interstates, I-94 has 597 miles between I-90 in Billings and I-29 in Fargo (ignoring unsigned I-194 in Bismarck).
If we were only counting 2dis, I-80 would win, because it's 646 miles between I-5 in Sacramento and I-15 in SLC. That's more than Quillz's guess, which is "only" 575 miles.
I believe that I-70 in Utah holds the record on an interstate with 108 miles of interchanges with no Services at interchanges on the interstate system.
US 77 in Kenedy County, Texas may not be the longest stretch of highway (non freeway) within a single county without a stop light or any kind of services, but it is sort of a longest in a sense. How much do you find a single county that has one main road, no major cities, a very small population, and no businesses and very primitive. When I-69E (oh I hate that designation) gets completed, the county's only major route of transit will be an interstate with no other non freeways as main roads.

I agree about US 77 in Kenedy County. I've never been there, but that's a stretch of road I want to drive some day. I like desolate areas and have seen a lot in west Texas. Such a long stretch of road without any public through road intersections is intriguing to me. I remember some years back a hurricane hit Kenedy County and caused very little damage because there was nothing there to damage. I remember it being reported that this storm hit the least developed county on the entire Atlantic basin coast.
