You're right historically though, when I-76 was I-80S.
Quote from: TheHighwayMan394 on October 04, 2021, 11:54:20 PMHow common is it for a US route to share the same number with the state route it replaced in a state? Besides what you had for US 12 in WI and MN, US 6 in Indiana used to be IN 6.
For its entre length in Wisconsin and a connecting piece of it in Minnesota, what became US 12 was coincidentally already called State Highway 12 in both states.

Post whatever random facts about interstates or US routes you have that you find interesting here. They can be as obvious, or as obscure as you like. I had plenty of facts over the past few weeks, but forgot about what all of them are about. Here's two I thought of in the shower today:
Of the x0 interstates (excluding wannabe I-30), I-10 interchanges with the most x5 interstates, while I-70 interchanges with the least. And none of them meet all 10 of them.
90: 5, 15, 25, 35, 55, 65, 75, 95 (8)
80: 5, 15, 25, 35, 55, 65, 75, 95 (8)
70: 15, 25, 35, 55, 65, 75 (6)

10: 5, 15, 25, 35, 45, 55, 65, 75, 95 (9)
Speaking of I-70, it's the only x0 without a 5xx 3di, a common odd first digit for 3dis for some reason, and sometimes, the only odd first digit 3di an interstate has (516, 520, 530, 579, etc). Also, I-40 doesn't have a 3xx 3di, another common first digit.

Yeah... I've been trying to verify it since it stood out to me also. If only Oregon named things internally the same way they do externally. Still looking at it.

Quote from: ethanhopkin14 on October 05, 2021, 02:31:02 PMEvery interstate can be important depending on how you look at it, not just x0s and x5s. I-81 is a popular trucking route for its diagonal routing and that it avoids most major cities. For a shorter route near me, I-71 is part of the routing between cities in the mid-south region like Dallas, Houston and New Orleans to cities in Ohio and the northeast. Some people on this forums (including me) see I-71 sort of like an "I-69E" to the whole I-69 system, continuing the SW-NE trajectory of I-69.
On that note, I am not in the boat of the I-30 and I-45 bashing. I-30 is an important connection from Dallas to Chicago or New York, while I-45 is basically I-35EE, part of that important corridor. Yes they are both short, but very important.

As designed every interstate was important, the only way for them to be unimportant would be if there was a change in design that neutered them.

Of the x0 interstates (excluding wannabe I-30), I-10 interchanges with the most x5 interstates, while I-70 interchanges with the least. And none of them meet all 10 of them.
90: 5, 15, 25, 35, 55, 65, 75, 95 (8)

Also, if I-69 is completed, it'll be the third longest N-S interstate (using 69E as the "main" branch of the three in south Texas), only below I-95 and I-75.
Quote from: jmacswimmer on October 06, 2021, 11:40:28 AMYes. I don't know the exact alignment through LA, AR and MS, but with a rough estimate, I got about 1705 miles in route length. For some comparison, I-35 is 1569 miles, I-94 is 1585 miles, and I-75 is 1786 miles. Another candidate for a longer I-45, and actually this one may be better, as Houston keeps their x5 :)Quote from: SkyPesos on October 06, 2021, 11:32:25 AM

I think it would also dethrone I-94 for longest interstate not ending in 0 or 5?
Quote from: hbelkins on October 06, 2021, 12:30:36 PMThat depends on who you ask. According to Google, it is one continuous segment. According to the signage on the freeway, there is a gap along that section, from Forks of Ivy to Asheville.
There's also a gap in I-26 between Asheville and Mars Hill, even though there's a freeway running between those two points.
Quote from: hbelkins on October 06, 2021, 12:30:36 PM
There is no gap in I-95. Or in I-70, except for Breezewood. In both cases, excepting Breezewood, the routes are continually signed on a freeway.
Now, I-69? There's a gap in it, between Bloomington and Indy, but that gap's being filled. There's a gap between Evansville and Henderson, but progress is being made on eliminating that gap. There's a gap between Mayfield and the area south of Memphis in Mississippi.
I would also say there are gaps in I-74, between the unfinished portions in North Carolina, but would not consider the section between Cincinnati and the NC/VA line to be a gap because there will never be an interstate between those two points. There's also a gap in I-26 between Asheville and Mars Hill, even though there's a freeway running between those two points.

I agree (https://www.google.com/maps/@35.6953726,-82.613483,3a,39y,13.39h,86.08t/data=!3m6!1e1!3m4!1sPx2--xf0qtt7ltuyjP69hA!2e0!7i13312!8i6656!5m1!1e1) ;-)

It appears as though most 2di Interstates ending in 2 or 7 are shorter and/or intrastate (or at least near-intrastate) routes.
You have: 2, 12, 17, 27, 37, (Future) 42, 72, 82, (Northern) 87, and 97.

The only 2-digit numbers never used on the US Routes are 39, 47, 86, and 88.
With 39, 86 (twice currently, thrice in total), and 88 (twice) in use on the Interstate system, that leaves 47 as the only 2-digit number never used on either the Interstates or the US Routes.

I don't think that really counts though because it basically amounts to a bridge toll, and everywhere else US 9 joins the GSP does not require a toll.
If you count that, then you probably have to also count all the US highways that cross a toll bridge - US 1/9 on the GWB, US 6/202 on the Bear Mountain Bridge, US 101 over the Golden Gate...

The following are the only 2-digit Interstates that stay within 90 degrees of their signed direction at all times:
19, 27, 57, 97
2, 12, 14 (ha), 16, 22, 42 (ha ha), 72 EB (WB breaks at I-55), 76 western, 86 western
Of these, four are multi-state though only 22 really has significant length in both. 57 is by far the longest.

US-35 in West Virginia has gotten considerably shorter over time without getting truncated.

New Silver Bridge (Kanauga) to US-60 St. Albans, about 45 miles (1969-2009)
New Silver Bridge (Kanauga) to CR-33 Scott Depot, about 37 miles (2009-2021?Maybe?)
I haven't seen the final tallies, but I suspect that when the four-lane is completed through Mason County that US-35 will be about half of its historical route length in the state.

Interstate 40 crosses four I-X7 interstates (planned for five with the I-57 extension). Two of which terminate on their north end at I-40, and one terminates on it's south end at I-40. I-X7 is the tied for third with I-X0 as the third most often repeated last digit in the system, behind X5(10) and X9(9)(just lacking CA-99 being re-signed as I-9). Significant that it is repeated that often, yet only four cross the same transcontinental interstate.

AADT Facts
Lowest (signed, not at a border) 2di: 1,700 in I-84 in Oregon just east of the I-82 intersection
This surprises me, as it suggests there is a higher amount of EB 84 traffic exiting towards 82 WB (and vice versa) - is there really more Tri Cities-PDX traffic than Boise-PDX traffic?
Yeah... I've been trying to verify it since it stood out to me also. If only Oregon named things internally the same way they do externally. Still looking at it.
Edit - Yeah, I'm not sure where OR Highway 2 branches off and I-84 becomes OR Highway 6, but looks like I read it wrong. I'll update.

Gonna infodump about Chicago real quick.
Interstate 294, the beloved (sarcasm) Tri-State Tollway by Chicago, is signed North and South, although the stretch of Interstate 94 it bypasses is signed East and West.
Interstate 355 was almost Interstate 455. The feds considered I-355 to be an outer beltway of Chicago with I-55 as its parent, but IDOT considered it a spur to Schaumburg. Nowadays, it wouldn't even be assigned an x55 number.
The Ohio Street exit on the north side is the way it is because it was supposed to be the exit to Interstate 494, a loop which would have run down Lake Shore Drive. It was never built due to low popularity.
Finally, the most interesting quirk
On the stretch of I-80 through Joliet, the speed limit was increased from 45 to 55 near the beginning of the 2010's. Literally no improvements were made to the road to justify the increase in speed limit, they just raised it without doing anything to the road.

The completion of almost all of I-79 in West Virginia reduced the travel time from Charleston to Morgantown from over 7 hours in 1965 to just a hair over 3 hours in 1977. Completion of I-79 to connect to I-77 in Charleston in 1979 whacked another 15 minutes off the trip. This was all in the NMSL days, so nowadays the trek only takes about 2h25min. The old route using US-119/WV-4, WV-4 and US-19 is roughly parallel to the current path of I-79. No wonder the State encouraged residents to drive along the sides of uncompleted portions of I-79 to get to Morgantown on gamedays.

Quote from: hbelkins on October 13, 2021, 11:24:19 AMI find the gaps between the x1 US routes interesting too. Going along I-80, there's roughly 130 miles between US 1 and US 11, 290 miles between US 11 and I-77 (former US 21), and 250 miles between US 21 and US 31. The next three are much more closely spaced compared to the previous three, with 65 miles between US 31 and US 41, 85 miles between US 41 and US 51, and 90 miles between US 51 and US 61. In my frequent trips between Cincinnati and St Louis, I thought it was sort of crazy that I can get all the way from 27 to 61 in just a 5 1/2 hour drive, a difference of 34, or 17 potential odd 2dus in between. There's also a bunch of unused or wasted US route numbers between 31 and 61, like 37, 39, 47, 55 and 57 (though I think 421 and 231 are long enough to be US 37 and 39 respectively, but that's fictional).
Is West Virginia the smallest state to have four x0's (30, 40, 50, and 60)?
Interesting how the first three are bunched together, then there's a bit of a gap between 50 and 60, and much of the state lies south of 60.

With the interstate grid "fixing" the US routes grid, there's one exception I can think of: Wisconsin. All 3 of its N-S interstates (39, 41 and 43) are east of the general line I-55 goes most of its way between New Orleans and St Louis. This happened because IDOT didn't want to extend 55, 57 or 65 to the Wisconsin line from Chicago, so Wisconsin had to find new numbers to use.

I always found it odd that I-35 in Texas replaced US-81. 35 (and 45 being close to it) is a number that's closer to the middle of the grid, which Texas is close to the center, but 81 seems way too far to the west. I found it odd that in Texas, the grid is already shifted to 81. Yes, the country is more sparsely populated heading west from US-81, so the grid can get more spaced out in the graduations, but I always felt it was too far shifted.

I-55,65 and 75 in Tennessee.
I-75,85 and 95 in Georgia.
Louisiana has four US x1:s 11, 51, 61 and 71.
Tennessee has five: 11, 31, 41, 51 and 61
The equivalent for US x0's appears to be Illinois - US 20, 30, 40, 50, and 60.

I know it's not intrastate, but it's worth nothing that US 59 is out of place in the grid, as it's entirely west of US 71. I think I saw in Fictional once to renumber it to US 73, which would make more sense as it's between 71 and 75 most of the way.

I also found it odd that US-87 was in central Texas, yet the next odd number up, US-89 goes east of the Grand Canyon and goes through Utah.
Quote from: US 89 on October 14, 2021, 01:54:50 PMThat was one of my numbering experiments that I did a while ago in fictional. Since the population of the west is significantly larger than back in 1926 (wow can't believe the US routes system is almost 100 years old!), I pushed some numbers west, starting from around the 50s range for odd numbers. Like I placed 51 on current 61, 61 on current 59/71, 71 on current 83, 81 on current 85/87, and 91 on current 93/95. This omitted the need for 101 on the west coast, and spread the numbers out a bit more in the central US.
I sometimes wonder if, had all roads designated as US highways today existed back then, if US 87 would have been assigned to today's US 191 through Arizona/Utah/Wyoming. That would have put it about halfway between US 85 and US 89 for the majority of its route.
Quote from: ethanhopkin14 on October 13, 2021, 01:48:21 PM
I always found it odd that I-35 in Texas replaced US-81. 35 (and 45 being close to it) is a number that's closer to the middle of the grid, which Texas is close to the center, but 81 seems way too far to the west. I found it odd that in Texas, the grid is already shifted to 81. Yes, the country is more sparsely populated heading west from US-81, so the grid can get more spaced out in the graduations, but I always felt it was too far shifted.
Yes the US Highway grid is was very very flawed, while the Interstate grid seemed to try to correct the errors made in the US grid, but the American southwest is one of the areas where the grid seemed to work, but the numbers seemed unnecessarily cramped (and by that I mean the north-south grid starts to run out of numbers even as far east as east Texas).
I also found it odd that US-87 was in central Texas, yet the next odd number up, US-89 goes east of the Grand Canyon and goes through Utah.
On another note, Texas is the proud owner of two horrible intrastate grid violators; US-57 and US-96. Now, while US-57 is basically a continuation of Federal Route 57, US-96 is a mystery as to why it was numbered that way. The only thing it has going for it is at one point it is south of US-90, but I for the life of me have no idea why it was numbered even although it's a north-south route. This isn't a fact, since I did no research on it, but are there any other states that have 2 or more US routes that are this level horrible grid violators? Intrastate would be preferable, but they don't have to be.

In 1958, California had no less than four US route shield designs for use on freeway guide signs: 1 digit, 2 digit, 3 digit where one digit is "1", and 3 digit. The one-digit shield, of course, was only ever used on US-6!

In the late '80s, I observed that Cincinnati was tied with several other cities for having the most U.S. routes within its city limits. I don't remember what the others were, but Lexington and Memphis may have been among them. However, I think Chicago once had more.
Quote from: hbelkins on October 06, 2021, 12:30:36 PM
I would also say there are gaps in I-74, between the unfinished portions in North Carolina, but would not consider the section between Cincinnati and the NC/VA line to be a gap because there will never be an interstate between those two points. There's also a gap in I-26 between Asheville and Mars Hill, even though there's a freeway running between those two points.

Post whatever random facts about interstates or US routes you have that you find interesting here. They can be as obvious, or as obscure as you like. I had plenty of facts over the past few weeks, but forgot about what all of them are about. Here's two I thought of in the shower today:
Of the x0 interstates (excluding wannabe I-30), I-10 interchanges with the most x5 interstates, while I-70 interchanges with the least. And none of them meet all 10 of them.
90: 5, 15, 25, 35, 55, 65, 75, 95 (8)
80: 5, 15, 25, 35, 55, 65, 75, 95 (8)
70: 15, 25, 35, 55, 65, 75 (6)
40: 15, 25, 35, 55, 65, 75, 85, 95 (8)
20: 35, 45, 55, 65, 75, 85, 95 (7)
10: 5, 15, 25, 35, 45, 55, 65, 75, 95 (9)
Speaking of I-70, it's the only x0 without a 5xx 3di, a common odd first digit for 3dis for some reason, and sometimes, the only odd first digit 3di an interstate has (516, 520, 530, 579, etc). Also, I-40 doesn't have a 3xx 3di, another common first digit.
Interesting.
I have always thought about how the I-35/I-10 interchanges in San Antonio are the most "connected" interchanges in the system (fitting since they share an alignment too). Since the aforementioned I-10 intersects with the most I-X5s and I-35 is the only I-X5 to intersect with all I-X0 interstates (I am not going to fight about how I-35 is actually 3 separate interstates and that it doesn't intersect with I-20 or I-30 since they actually intersect I-35E and I-35W from east to west respectively). Basically the only one missing is I-85, but a short jaunt up I-65 from Mobile gets you to I-85 so it can be easily forgiven.
Separately, I-30 and I-85 are cousins, as they are the only interstates to default on both ends onto another "like" interstate (I-85 from I-65 to I-95 and I-30 from I-20 to I-40), making their short or relatively short life being part of a much larger route.
On that note, I am not in the boat of the I-30 and I-45 bashing. I-30 is an important connection from Dallas to Chicago or New York, while I-45 is basically I-35EE, part of that important corridor. Yes they are both short, but very important.

A picture of the western portal of the Pennsylvania Turnpike's Kittatinny Mountain Tunnel is featured as the first postcard during the opening credits of National Lampoon's Vacation.
The image is from before the tunnel was twinned, and before designation as I-76, but still an interesting random fact.

495 - DC and NYC
Quote from: SkyPesos on January 21, 2022, 11:14:34 PMUS-11 obviously has the most due to the NE-SW angle it travels.
Every x1 US route each x1 meets (or used to meet)
US 1: 21, 41
US 11: 21, 31, 41, 51, 61
US 21: 1, 11
US 31: 11, 41
US 41: 1, 11, 31, 41
US 51: 11, 61
US 61: 51, 71
US 71: 61
US 81: None
US 91: 101

Quote from: Henry on October 06, 2021, 10:25:01 AMFor non-x5, I think I-77 is the winner, meeting 20, 40, 70, 80 and 90 (5).
Well, since you mentioned x0s meeting x5s, I'm flipping the script and doing the reverse. And I'm doing the full list this time, including the impostor I-45 (and BTW, I-30, which was excluded from the above list, meets 35, albeit split into two, and 45).
5: 10, 80, 90 (3)
15: 10, 40, 70, 80, 90 (5)
25: 10, 40, 70, 80, 90 (5)
35: 10, 20, 30, 40, 70, 80, 90 (7)
45: 10, 20, 30 (3)
55: 10, 20, 40, 70, 80, 90 (6)
65: 10, 20, 40, 70, 80, 90 (6)
75: 10, 20, 40, 70, 80, 90 (6)
85: 20, 40 (2)
95: 10, 20, 40, 80, 90 (5)
So I-85 interchanges with the fewest x0 interstates, and I-35 interchanges with the most. Of course, I-50 and I-60 don't exist, so none of them will meet all 9. Had I-70 and I-95 met as planned, it would've been 7 for I-70 and 6 for I-95.

It’s worth noting that Vermont doesn’t have any x1 or x0 US routes. They have US 2, but that doesn’t really count since it’s discontinuous. On another note, Vermont, North Dakota, Alaska, and Hawaii don’t have an x0 or x5 Interstate.
By contrast, New Mexico only has x0 or x5 interstates.
So does Wyoming.
The City of Dallas has more combined x0 and x5 interstates than New Mexico and Wyoming.
I don't think that's right.
Dallas has I-20, I-30, and I-45, with I-35E being debatable.
New Mexico has I-10, I-25, and I-40, and Wyoming has I-25, I-80, and I-90.
Combined then, New Mexico and Wyoming have 5, which is more than either 3 or 4.

I tried to word this in a way that I wouldn't get scrutinized by technicalities in verbiage or suffixed routes. Looks like I failed:
The City of Dallas has more combined x0 and x5 interstates than New Mexico and Wyoming.
The City of Dallas has more combined x0 and x5 interstates. I worded it that way so that no one would be confused if I was talking about x0s and x5s individually, or the group as a whole. I looked into the future and thought "if I don't specify combined, people will think I am saying Dallas has more x0 interstates than New Mexico and more x5 interstates than New Mexico." Truth is it has the same number of x0s as New Mexico, so I meant x0 and x5 as a group. That tally is Dalls-4 (I-35E, I-45, I-20, I-30), New Mexico-3 (I-10, I-40, I-25) That's two x0s for both and two for Dallas and 1 for New Mexico x5s if you are scoring at home, and also to take any confusion out of it. I hope that's clear.
than New Mexico and Wyoming. I should have said "individually" at the end of that sentence so that it would be clear I was talking Dallas vs. New Mexico and separately Dallas vs. Wyoming and NOT Dallas vs. New Mexico/Wyoming super state. My fault, but I really thought the sentence was pretty obvious and decided to drop the "individually" for the sake of brevity.
As for I-35E, it's an x5 if you say I-35 goes from Laredo, TX to Duluth, MN. If you say it's three discontinuous routes, then I-35E is just a 3di and that sentence is a lie. Mainly, you cant say its one route from Laredo to Duluth and also say I-35E (or I-35W) is not a part of I-35. Can't have it both ways.
In conclusion, I tried wording that sentence in a way that I wouldn't have to go through the above explanation and could get my point across in one sentence. Plus, it was just a wacky stat that made me think its crazy a city has more mainline interstates than an entire state.

Illinois actually had 6 x0 US routes planned at one point, with US 10 planned to use US 12's routing between the Twin Cities and Detroit via Chicago in the early days. Pretty impressive if you ask me.

Same deal in Arizona, although they did have two 3dis at one point. I-410 being used on the southernmost piece of I-17 and I-510 for AZ 51. There was also I-710 planned for Tucson.

For those interested in Interstate trivia, the FHWA Interstate Route Log and Finder List has been updated as of Jan. 26th. Unfortunately, the 2di Table 1 does not include all new interstate designations, such as I-42 in NC, there are some new listings in Tables 2 and 3, such as for I-587 in NC and I-195 in DC:

I thought that Paseo del Norte (NM 423) was supposed to be a loop, but fizzled out for one of the typical six reasons (no money, freeway revolt, land acquisition failure, environmental impact, no demand, physically impossible).

Has anyone ever done an analysis of US 62 to determine if it's more E-W or N-S? I've seen some people comment on other diagonal routes, such as I-71 (signed N-S), US 42 (E-W in Kentucky, N-S on Ohio), I-26 (E-W), and other routes. There's some type of formula that can determine if a route is more N-S than E-W, but I don't know what it is or how to apply it.
Quote from: HighwayStar on February 12, 2022, 09:02:53 PMI'm pretty sure that was used for I-4, and the E-W distance beat out the N-S distance by a small margin, which is why it's an E-W highway.
A simplistic approach would look at the delta in longitude versus the delta in latitude.

Potential problem: the size of a degree of longitude increases the closer you get to the equator.
Quote from: CNGL-Leudimin on February 16, 2022, 03:03:30 PMSF to Sacramento is probably the most noticeable dip in US 40 as a whole. Sacramento is about the same latitude as St Louis (both at 38.6), which US 40 also dips to the south to serve.
However, when it extended all the way to California, it dipped considerably South after Winnemucca. It should have passed through Redding.

Quote from: Mapmikey on February 26, 2022, 04:38:13 PMWill this be true when I-49 is complete? Currently, the Texarkana bypass section truncates at US 71 on the state line. The ramps go into Texas according to Google Maps, but I don't know the accuracy of the state line shown. In any case, it does look like I-49 will eventually go through a tiny bit of Texas.Quote from: ethanhopkin14 on February 26, 2022, 03:45:08 PM

US 21 is an exception to the "x1 US routes are major" rule, even in its peak length. Four of its neighboring N-S routes (19, 23, 25 and 27) are longer than it, probably because 19 goes through FL, 25 goes through MI, 23 and 27 goes through both, and 21 goes through neither. I wonder how US 21 got the x1 designation then...

That's because US 21 used to run to Cleveland, Ohio before I-77 came along. Back then, it was a true x1 US highway. Now it ends in Wytheville, Virginia. And also, 21 is west of 19, which was done to keep the grid in order.

Shoot, I did miss that. Maybe US 21 could have reached Florida if it were sent down US 301 in Orangeburg, SC and assumed that all the way down to Sarasota with the rest of 21 becoming a state route. 301 is rather long for a 3dus.

US-191 is an original route but has nothing in common today with it's original route.
I don't know if it's the only one, but still pretty unusual.
Quote from: CNGL-Leudimin on April 05, 2022, 08:28:25 AM
Well, AFAIK US 191 has a section of its original route in West Yellowstone (and unofficially to Madison Campground), but it is now reversed (what was originally North is now South and vice-versa), and for a time it wasn't part of US 191. US 601, on the other hand, has none of its original route remaining.
Quote from: ethanhopkin14 on April 05, 2022, 10:36:17 AMThree of the x21s (221, 321, 421) are longer than US 21. 421 is long enough that it probably could've been US 37, and 231 as US 39, but that's fictional.
On the subject of US-191, how many 3dus are longer than their parent? In US-191's case, comically longer that it is now a border to border highway.

Quote from: vdeane on April 15, 2022, 08:17:03 PMI thought I-95 was using a continuation of I-80's mileage between the NJ Turnpike and the GWB east of the latter's terminus. Forgot to mention that in the other post, but I thought it was interesting that one interstate is continuing another interstate's mileage and exit numbers past a terminus, like how I-70 continues I-270's mileposts in IL.
I-95 doesn't have a concurrency with I-80. I-80 ends at I-95 and the exit numbers there are based on the mileage from I-95's originally planned route in NJ (note that this section was also originally under NJDOT jurisdiction before being transferred to NJTA). The numbers even continue south of I-80 (https://www.google.com/maps/@40.8597828,-74.0119368,3a,32.7y,195.9h,92.85t/data=!3m6!1e1!3m4!1scnWrjEUx7X9fCM-zfUnMcw!2e0!7i16384!8i8192).

The "roundest" 3-digit interstate, in terms of prime factors, is Interstate 384. It's 2^7 * 3. All other existing 3di's have prime factors larger than 3.

List of all interstate concurrencies for each 2di with one or more, and the ones that they keep and lose exit number continuity in. If two interstates start at mile 0 at the same point in a state, and both of them continues the mileage after the concurrency instead of resetting to 0 (like I-20/59 AL or I-55/64 MO), it's neither a win nor loss for either interstate.

I thought of constructing a ranking of all interstates from this, but then I realized that can't be consistently done. 40 outranks 55, which outranks 70, which outranks 35, which outranks 40 again.

Cool, so I'm not the only one who thinks about numbers this way!
It's the Interstate highway with the MOST composite number!
I wonder what the US Highway is with the most composite number? 360 or something?
Quote from: pderocco on April 01, 2023, 12:34:44 AMAlso, two of them with 4 different prime factors that currently don't exist: I-570 (2*3*5*19) and I-870 (2*3*5*29) are under the same parent interstate, and both have been proposed as a number for a freeway in the past.
How about this? The roads with the most different prime factors are I-210 (2*3*5*7), I-390 (2*3*5*13), I-510 (2*3*5*17), I-630 (2*3^2*5*7), I-690 (2*3*5*23), I-780 (2^2*3*5*13), I-840 (2^3*3*5*7), I-910 (2*5*7*13), and I-990 (2*3^3*5*11). There are none with five, because the smallest possible one (2*3*5*7*11) doesn't fit into three digits.

With the exception of I-2 (being the only even prime it's also the only prime 2di to go East-West) any prime interstates must either go North-South (2di) or branch off a North-South 2di (3di)
For US Routes is simpler: any prime US Routes, with the exception of both instances of US 2, must run North-South.

Interstates that don't use their own mile markers/exit numbers through the majority of their route through a state:
I-80 IN: Shares mile markers with I-94 for its first 16 miles, then uses I-90/ITR's mile markers east of the I-94 split. Note how I-80 in Indiana doesn't even have its own Wiki article due to being entirely concurrent with other interstates in the state.

If I-69 in TX gets finished, it would be about 350 miles south of I-10 to the Mexico border via the 69E branch.
