have fun.

all I know is US-160 is longer than US-395, US-183 has gotta come close, and a lot of the eastern north-south connectors (421, 231, 441, etc) are about 900-1000 miles each.

Lengths are approximate, but this list (scroll down) probably has them pretty close to the right order.

I dunno, you're the one making up the list!

I would consider it as a 2dus since it fits in that grid.  Now if it was on the Eastcoast, it would be a 3dus.

please do not post long lists of easily findable information.

especially if it is incorrect.
