Thinking 319 might be tough.  Here are the intersections/concurrencies that show up from TM data:

I-474 And I-155 between Peoria and Morton, IL gets it done. I'll post a pic later =)

At least, maybe I will...They are adjacent interchanges on I-74, and I could have sworn there are BGS's with both routes listed, but so far, any picture sites, I am not seeing any...

And I don't live in that town/part of the state anymore, or I'd go and get one right now!

I'm giving IDOT a big fail on this...not having much advance signage on I-74 for either I-155 or I-474, and no signage on either 3di directing you to I-74 to make the connection

A well placed mirror with a clever camera angle would get both shields in the same shot!

By the 48 hour rule, I'll post this GSV screenshot of NY-31F and NY-350.

350 - 31 = 319

One I found on GSV for 319, from Dallas, TX. Loop 354 and I-35E

These must not be complete lists. What about US 1 and US 321?

350 - 31 = 319

So what exactly is that in the road?

It's definitely not a complete list, just the ones I am easily able to detect from TM's master graph.  Usually when my program fails, there's something odd or unusual with the labels used for the graph.  I know there are a lot of concurrencies there in Columbia where these meet but I'm not sure what caused it to fail to detect.

In any case, happy to hear there's one that looks likely for someone to be able to track down (I don't have one).

Edit: thanks to your note, I noticed some additional ways my program can detect possibilties.  320 is not looking so hard now.  In fact, I have some.

Hey Jim.  This is one of your pictures!  I farmed this from the 1-2-3 Take it Yourself Challenge.

It's been a few days, so I will post again to keep us moving.

412 - 84 = 328.  I-55 in Missouri.  July 2, 2012.

Another 24 hours+, so I'll continue again.

I can provide 334 - 5 = 329 close to home.  This is in Fonda, New York.  November 2, 2008.

[paulthemapguy]

Thanks to Jim.  I didn't have a 328 or 329.  My ability to contribute has dropped off a lot getting into the 300s.

334 - 4 = 330

377 - 44 = 333 (Stroud, OK). Pretty sure that was a sign error, with an OK State Route 377 shield, instead of US 377 shield. Those shields have since been replaced, with a US 377 and the newer style OK State Route shields for 66 and 99
