Signed:  I-94/US 59/MN 210.  Technically, US 52 is part of it as well but is unsigned.  So I guess this is both correct and wrong given the OP's criteria.


Highway63

I-380/US 218/IA 27 between Cedar Rapids and Iowa City, I-380/US 20/IA 27 east of Waterloo, and I-35/US 18/IA 27 south of Clear Lake.

There are 2 in SE Wisconsin both on the same highway.
I-41/US 45/WI-100
I-41/US 45/WI-167
Also one up by Manitowoc
I-43/US-10/WI-42
Also one in Hudson
I-94/US-12/WI-35
And yet another one
I-39/US-51/WI-23
If I-39 is ever extended north you will have
I-39/US-51/WI-29

Cap City Freeway Sacramento, CA US-50 is cosigned with I-305 and CA-99, and CA-51 plus cosigned with Business 80 on the North/South Section of CA-51.

Counting only signed routes, or unsigned ones too?

If we count only signed routes:
I-20/US 278/GA 12 (as mentioned by formulanone above)
I-75/US 41/GA 7 between Valdosta and Hahira

If unsigned routes also count:
Neither of the above (also GA 402 and GA 401, respectively)
I-285/US 19/GA 407
I-16/US 17/GA 404

Not eligible:
I-516/US 80 and I-516/US 17 involve four state routes, three of them signed
I-985/US 23 involves two unsigned state routes (365 and 419)

74/171FAN

I-78/US 22/NJ 173 near Clinton, NJ though this one is very brief

.

The I-93/US 1/MA 3 also has a silent MA 1A concurrency for most of its length.

While true (good luck trying to follow 1A on/off I-93/US 1 in Downtown Boston near the Sumner/Callahan Tunnels); such isn't really worth mentioning (in the spirit of this thread) since there's already a visible concurrency along I-93 & US 1 along the O'Neill Tunnel/Expressway/Southeast Expressway w/MA 3.

I accept and respect your identity as long as it's not dumb shit like "identifying as a vaccinated attack helicopter".

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

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

I-255/US 50/IL 3, between Exits 6 and 10, between Columbia and Dupo, IL, Southeast corner of STL Beltway/Bypass/whatever

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.

Two other (questionable) ones from the North Star State:

I-94/US 52/MN 27
I-94/US 12/MN 95

We could do WI for a while probably.

I-94/US 12/WIS 35
I-39/US 51/WIS 23

I-20, US 84, TX 70 Southeast of Sweetwater TX

Technically I-70/US-6/CO-9 between Frisco and Silverthorne, CO, but CDOT despises signing Interstate/US Route duplexes.

At least they reluctantly co-signed CO-9 with I-70.

I-72, US 36, and IL/MO 110 near Quincy, IL/Hannibal, MO...

Thanks to that CKC Expressway...

And going historical, part of present I-88 and IL 110 used to be Toll US 30, tho it was never all 3 at the same time

MA 1A officially is routed northbound via I-90 East to East Boston. There are To 1A trailblazers on the ramp from I-93. Also MA 3A runs as a silent concurrency from Neponset Circle north to Storrow Drive, so north of Exit 12 you are on I-93/US 1/MA 3/(MA 1A)/(MA 3A)
