Interstate, US, State Routes all concurrent with eachother

I-39/US 51/WI 23 north of Portage
I-94/US 12/WI 35 in Hudson

- (Future) I-41/US 41/45/WI 100 and I-41/US 41/45/WI 167 (NW Suburban Milwaukee)
- (Future) I-41/US 41/WI 32 (Green Bay).

OH 37 / US 36 / Future I-73

Shouldn't this be in Fictional Highways? 

Fictional would be if I said I-73 / US 23 / OH 315.

[SD Mapman]

In western South Dakota, SD 34 overlaps with I-90 and US 14 NW of Sturgis, then going SE from Sturgis, SD 79 overlaps the 2 until the east end of Rapid City.

Towards the end of the 79 concurrency, there's also an overlap with 16 Truck.

[Gulol]

I-25, US 87, SH 88 through the Denver Tech Center (unsigned, of course) ... unless the state highway portion was relinquished.  Someone here I'm sure knows this better than I do and can confirm if this is no longer valid.

I 49 US 71 US62 and AR 16 in Fayetteville

I'm surprised no one has mentioned the I-465, I-74, US-40, US-36, US-31, SR-37, SR-67 concurrency on the south side of Indy. I know, there are no reassurance signs along the way, but this is clearly not a case where the DOT just assigns state numbers to the Interstates. The state and US highways are clearly signed as turning onto the Interstates.

You forgot about the one-mile stretch on the southeast side between Washington St. and Brookville Rd. where it's I-465, US-31, US-36, US-40, US-52, US-421, IN-37, and IN-67. Too bad they're not signed in that stretch.

I stand corrected (or at least clarified). I hadn't included 52 and 421 because I wasn't sure that INDOT signed them at their entrances to the loop. As far as I can tell from GSV, 421 is not signed as turning onto 465 on the SE side, but it clearly is on the NW side. US-52 is signed as turning onto 465 on the SE side.

It would be a hoot to see a pull-through BGS or reassurance markers with all those highways on it. It's a shame none exists. Talk about sine salad!

Maybe someone with more sign designing skill than I could put one together. If I have it right, it would be North I-465, North US-31, East US-36, East US-40, East US-52, North US-421, North IN-37, and North IN-67 for traffic actually driving north in that one mile stretch.

In Texas you can potentially have four categories: Interstate, US, State Highway and Farm-to-Market Road.

[kphoger]

More, if you count spur and loop routes separately from the other classes.

[route56]

I-135, U.S. 81 and K-4 briefly in Saline County. I guess that makes K-4 the only K-route that is part of more than one of the concurrencies.

K-5 is briefly concurrent with both I-435 and I-635 in Kansas City

I-635 has a concurrency with K-5 for a short while, which I think makes it the only Kansas Interstate that's concurrent with a K-route but not a U.S. route at the same time.

In addition to the 435/K-5 concurrency, I-235 and K-96 are briefly concurrent.

Any county routes concurrent with all 3 higher classifications?

Any county routes concurrent with all 3 higher classifications?

No. County routes on Interstates are extremely rare (I-40/CR 66 near Barstow, I-295/CR 551 near Deepwater, any others?).

[cl94]

New York has very few examples because US routes tend to remain on their old alignments or, in the case of Western New York, get demoted to state routes. There is only one and it's I-86/US 219/NY 17 east of Salamanca. Region 5 doesn't even acknowledge NY 17's existence. There are only 3 other Interstate-US Route concurrencies I can think of (I-95/US 1, I-95/US 9, and I-99/US 15 (soon to be gone as well)) and one more (I-86/US 6) in the future.

Interstate-NY Route concurrencies, however, are pretty common.

[NE2]

one more (I-86/US 6) in the future.

Which will overlap NY 17M between exits 123 and 125.

[NJRoadfan]

NJ has one, I-78/US-22/NJ-173, its lasts one exit and isn't signed. CR-551 in Deepwater might not even count, most counties don't acknowledge multiplexes, treating them as breaks in the route.

[ctsignguy]

Connecticut used to have one...
