Nope, I'll come back and stop there when I'm not by myself.

Boredom and working with regular expressions all day got me curious.  I filtered out the concurrency list from the Travel Mapping site (US/Canada only).  Not a complete list because of the way I filtered and Travel Mapping doesn't have all routes, but interesting.
This is Doing It Right. :D Bravo, sir!
And you beat me to it; everything I was about to list for Maine is there. So here, have some GMSV. Quite a few Useless Multiplexes here...

US1/2
US201/202
ME4/5
ME15/16
ME117/118 (useless)
ME129/130 (useless)
ME150/151
ME151/152
ME169/170 (useless)
ME175/176

And a historic honorable mention: ME179/180 (useless)
ME180 was relocated on Monday 2013-07-29.

Before The Maine Great Renumbering, there may have been other examples. It's tempting to think that 123 & 124 may have been multiplexed -- the original ME124 ran from the south end of modern ME24, across what later became the Brunswick Naval Air Station, and intersected ME123, most likely at Garrison St. I doubt they were, though: The route log on the back of the State Highway Department's 1932 map has 123 ending at 124. The Useless Multiplexes listed above all came into being After the Maine Great Renumbering. In many ways, our highway system was a lot more sensible then. and this is where our rampant multiplexing got its start.
"Officer, I'm always careful to drive the speed limit no matter where I am and that's what I was doin'." Said "No, you weren't," she said, "Yes, I was." He said, "Madam, I just clocked you at 22 MPH," and she said "That's the speed limit," he said "No ma'am, that's the route numbah!"  - Gary Crocker

In NC, I-73 and I-74 run together for a good while. Also NC 904 and 905 share about 1/2 mile of pavement.

In California, we have no legal concurrencies and very few signed ones. For as many signed highways as we have, we have surprisingly few instances where consecutively numbered highways even intersect. I know about I-5 and CASR-4 in San Joaquin county. It may be that CASR 1&2, 90&91, and I-10 and CASR-11 intersect, but I haven't checked it out lately.

Not sure if this has been mentioned, but US 50 and US 51 are concurrent for about 1/4 mile in Sandoval, IL:

I mentioned it earlier, but did not post a pic. I've driven thru it both on the North/South US 51 route and on the East/West US 50 route
