Longest state highways

[Dr Frankenstein]

Going international, in Quebec, R-132 is 1,611 km (1,001 miles) long, and R-138 is 1,521 km (945 miles) long with all the segments added up (1,420 / 882 for the main segment).

Problem with 35 is it's a road no one would actually drive end to end.

Why do you say that? It's mostly the Great River Road south of Prescott, so a lazy tourist from Duluth might decide to stick with 35 rather than follow county roads in the places where the GRR leaves.

I suppose the original WI-13 probably wins hands down.

Actually the original WI 10 (now US 51 and US 2) wins. Numbers were deliberately assigned in reverse order of length.

Would that have made WI 11 longer as well then?

Not longer than 10 was.

South of Prescott 35 isn't the fastest route to get from point A to B. That's probably what he meant when he said people won't drive it from end to end.

Example: although 35 goes directly into La Crosse, traffic is advised to dump 35 at Galesville for US 53/WIS 93.

Yes, it officially duplexes on I-5.

I thought ODOT doesn't sign duplexes or even acknowledge their existence?

Really.

I meant that there are so many twists and turns unless you were deliberately driving 35 to drive 35 you wouldn't.   It's pretty much straight south from SUperior, jogs way west to Houlton & Hudson, then doubles back to River Falls, then back to Prescott.  I'd take that jog out since you could go from Hudson to Prescott on county F and it's a lot faster.  I'd reroute US 10 over this stretch, leaving the WI portion to be an extension os WI 72 and MN could be MN 95.  If 10 can't be rerouted, I'd just give the Hudson to Ellsworth highway it's own new number.

I stand corrected, though Google Maps goes out of their way to point out concurrencies that aren't signed (i.e. CA 99 and CA 16 along the W-X portion of Business 80)

Oklahoma 3  goes all the way from the Colorado  border  to the Arkansas border,  I haven't added all the miles , but that would    certainly be right up there  with  CA 1.  Texas  6  and  Texas 16  are two others that come to mind  also.

Did find this, which just has the longest one in each state. Sure looks like MT/ND/MN 200 could be a US highway

That's because in California, most route definitions actually have gaps over overlaps with the overlap being implied, with a few exceptions.

[NE2]

At some point, the Goog ran an algorithm to add overlaps between segments of same-numbered routes, whether or not they exist on the ground. Arkansas has a bunch of bogus ones, and Kissimmee, FL still has CR 532 on old US 17-92.

The Google says that OK 3 is 558 miles long, while Wikipedia claims that it's 615 miles long. Which is right?

[Bickendan]

Wikipedia includes OK 3E's miles as part of OK 3's.

[bugo]

Wikipedia includes OK 3E's miles as part of OK 3's.

OK 3E ≠OK 3.

OK 3E ≠OK 3.

MNDOT disagrees in terms of I-35E's exit numbers: I-35's exit numbers (and mileage) follows I-35E through the Twin Cities.
I believe the same happens in Texas.
With that precedent, I can see why OK 3 and 3E would be combined for a single mainline mileage, and why I would do the same for OR 99 and 99E.
