(last updated 12/9/2023) Lots of people (myself included) have an odd fascination with the superlatives of just about any topic. As it relates to highways, a common question is "What is thelongest US route?" (answer) And then related questions branch off from there:
Whatwas the longest US route historically? (answer)
What is the longest 3-digit US route that runseast-west? (answer)
Eventually the questions start swinging around to the opposite extreme, and those are the topics of this post. Specifically we set out to answer these questions:
What is theshortest US route?
Whatwas the shortest US route historically?
What is the shortest2-digit US route?
Whatwas the shortest 2-digit US route historically?
