I-70, US 40, and K-4 in Topeka,  KS, which is joined by US 75 in the middle
MORE FUN THAN HUMANLY THOUGHT POSSIBLE

I-99/US 220/PA 26 north of State College is the only case of this in Pennsylvania.
Mileage-based exit numbering implies the existence of mileage-cringe exit numbering.

Quote from: bob7374 on July 18, 2017, 11:44:45 PMMA 1A officially is routed northbound via I-90 East to East Boston. There are To 1A trailblazers on the ramp from I-93.
Yes, there are TO 1A trailblazers and even a supplemental BGS directing airport/E. Boston-bound traffic along northbound I-93/US 1 traffic to use I-90 East (Exit 20); however saying that such is the official 1A from its northbound parent is open for debate; especially since MA 1A northbound does exist via the Callahan Tunnel. 

A northbounder could theoretically exit off I-93 further north at Exit 23 and follow surface streets (North to Congress to New Chardon) to MA 1A North & the Callahan Tunnel.  The only logical reason for anyone to do such (outside of a roadgeek seeking a clinch) would be if the Ted Williams Tunnel was closed for repairs, accident and/or police activity.

As you know, this oddity w/1A was the result of the Big Dig project not building/providing direct access to all the harbor tunnels from both directions of I-93, and US 1 being rerouted from Storrow Drive onto I-93 just prior to any Big Dig-related construction.  To be sure, there are issues with these partial interchanges but I can assure you that any related-complaints are because of partial-access to/from the tunnels themselves and not because of a route number discontinuity/interuption.

I-35 / US 50 / KS 31:

Leudimin's edit: changed state route to unified nomenclature

Now we need to find a way to put a county route going West there :sombrero:.
Supporter of the construction of several running gags, including I-366 with a speed limit of 85 mph (137 km/h) and the Hypotenuse.

Please note that I may mention "invalid" FM channels, i.e. ending in an even number or down to 87.5. These are valid in Europe.

Careful, the folks from Michigan and Kansas stand by their single-letter-and-hyphen road abbreviations!

Do Business Routes count?  Bus I-94, Bus US-127, M-50 in Jackson.

Else I can't find any in MI.  The fact that there's only 2 Interstate/US concurrencies of any consequence contributes to that greatly.


At the time it opened in 1962, a section of the north—south freeway in Grand Rapids was signed as I-296/US 131/M-37, but later M-37 was moved and still later I-296 was removed from signage.

Cap City Freeway Sacramento, CA US-50 is cosigned with I-305 and CA-99

Except that I-305 is not signed (but should).

Wouldn't mind seeing it signed.  But it also used to be I-80, I think, before it was rerouted on the northerly bypass of Sac'to (proposed I-880 at the time).

I-20/I-59/US 11/AL 5 between Bessemer, AL and Green Pond, AL. If unsigned ones also count, then any instance of a US route multiplexing an Interstate will bring a state route with it, such as AL 3 for US 31.
It's all fun & games until someone summons Cthulhu and brings about the end of the world.

I also collect traffic lights, road signs, fans, and railroad crossing equipment.

This thread is about exactly one of each. That one has two Interstates, so it doesn't count.
Clinched, minus I-93 (I'm missing a few miles and my file is incorrect)

Traveled, plus US 13, 44, and 50, and several state routes

I will be in Burlington VT for the eclipse.

I have no words.
Yeah - he forgot CA 16, which disqualifies the whole shebang :bigass:

There are 2 in SE Wisconsin both on the same highway.
I-41/US 45/WI-100
I-41/US 45/WI-167

Also US 41. I-41 is a glorified section of it with the very same number.

Actually, neither is CA 99, except for trailblazer "TO CA 99" signage on the BGS's approaching US 50 from NB 99 and SB I-5, directing 99 traffic over the W-X freeway in either direction.  There's also "TO CA 99" signage on the WB US 50 BGS approaching NB I-5.  Otherwise, not a reassurance shield for either US 50 or CA 99 to be found on that stretch of freeway.  I-305, OTOH, would be completely redundant; Caltrans has elected to publicize US 50 as the primary "target" route EB, and "TO I-80" likewise for WB.  I-305 is simply a funding mechanism for maintenance of that segment, plus the chargeable part of unsigned CA 51 north from the US 50 interchange to the C street/UPRR underpasses, all of which was original I-80 before the '82 changes.

The OP's asking for concurrencies containing one of each route type (one Interstate, one US and one SR) for a minimum total of 3 routes along stretches.

And to sign the entire quinplex (I-305, Bus I-80, US 50, CA 16, and CA 99) would definitely violate message loading guidelines, as awesome as it'd be to see it in its full glory.

Yeah, even GDOT thinks that would be a bit much. (At least I assume that's the reason for not signing southbound 25 here, and leaving out 26 entirely.)

Also Business 80 was previously signed for the west end of US-50 but was removed last year. CA-51 is the only one keeping the business 80 signs for now.
