Consecutive Route Changes In Numerical Order...

You can do US 1-US 2-US 3-US 4-US 5-US 6-US 7, albeit in 5 states (ME, NH, VT, MA, CT).

You can also do MA 8-MA 9-MA 10.  And, US 7 and MA 8 pass within about 1.5 miles of each other in Lanesboro, MA.

PA doesn't have many with 3 turns, and none 4 or more that I could find.

PA 29 S -> US 30 W for over 200 mi -> PA 31 W
PA 74 N -> PA 75 S -> I-76

There could be a long one with PA 14 S -> US 15 S -> PA 16 IF the PA border was about 5 miles further south than it is...

I can only think of a few consecutive route junctions in Nevada that involve more than two route numbers. There aren't many consecutive route numbers that intersect due to county clustering, the sparseness of routes in many areas of the state, and the method in which numbers are assigned in more route-dense areas.


SR 397 -> SR 398 -> SR 399, all in the Lovelock area.

SR 429 at Washoe Lake -> SR 430 (semi-hidden, concurrent with US 395) near Bower's Mansion north of Washoe Lake -> SR 431 at Mt Rose Junction on the south end of Reno.

SR 445 in Sparks -> SR 446 near Sutcliffe/Pyramid Lake -> SR 447 at Nixon/Pyramid Lake

If you can u-turn and go out of order, in WA you can go 522-523-522-524-527-526-525.  I know you cant, but as far as something that could theoretically be done in around an 90 minutes... 

Otherwise, I don't think Wa gets past 3

You can do US 1-US 2-US 3-US 4-US 5-US 6-US 7, albeit in 5 states (ME, NH, VT, MA, CT).

That requires making a U-turn (only direct connection between US5 and US6 is 5N→6W).

The best I can think of in VA is VA 28-US 29 and really you could just continually do that going around in circles

There's US 1-VA 2-VA 3 too, but idk if its been mentioned.

I'm at a loss to find one in NC.  Seems like routes are separated by entire regions in the state. Unless you count the multiplex of I-73 and I-74.

I 95/NC 96/NC 97
