Mile 216  -->  M-216

Eeee...it's the devil's number for multiplication; 216 = 6*6*6

Time to advance to the next cube of a whole number, which is decidedly luckier: 7*7*7=343

Arkansas 343 to Stuttgart:

While it doesn't affect the game, I want to point out that the devil's number is explicitly 666, not just three sixes in a row. The concept existed before people used base 10. So while the sum of numbers on a roulette wheel qualifies (0+1+2+...+35+36=666), anything involving three separate sixes (6×6×6 as you mentioned, the date 6/6/06, etc.) does not, nor does any number with more than three sixes. Two thirds (0.6666666...) is right out.

Exit 25 to I-25 (somewhere between Colorado Springs and Denver, CO):

[Jim]

A double match, so you can play either: 25 miles to I-95 from US 98 and US 441 in Port Mayaca, Florida.  June 29, 2022.

[oscar]

By "double match", I assume you're playing both I-95 and 25 miles from I-25.

On that assumption, I-95 => I-195 (which I was going to play for MA 25):

[fwydriver405]

I-195's (MA-RI) eastern terminus in Wareham MA -> 72 km (45 mi) to the west, I-195's western terminus in Providence RI (previously played for Exit 1A, as well as 1B-C-D), July 16, 2020.
