Spoiler
This question had the most consistent distribution of responses in the entire game. I enjoyed this one, and I think many of you did, as well – particularly if you knew how to use the map to your advantage.
If you're unfamiliar with how Interstates are numbered, even routes tend to go east-west, and odd routes north-south. Numbers usually get higher as you go from south to north (evens) and west to east (odds). Routes ending in 5 or 0 are 'major', often spanning the entire country.
There are exceptions, of course, and I highlighted a notable one (I-99) here. Also, it's worth noting that Interstate 2 opened in 2013 in Texas, usurping Interstate 4 as the lowest continental number.
