What is an interstate highway?

Interstate highways typically connect more than one state—but, just like with I-37, that’s not always the case. There are other criteria, as well, like having limited access and being a connection between major cities or towns.
Ever wondered how interstates are numbered? Typically, interstates are designated by either a one- or two-digit number. Most north-south routes, including I-37, are given an odd number, while east-west routes typically have an even number. And major interstates typically end in either a zero or a five.

What states does I-37 run through?

Believe it or not, I-37 only runs through Texas, the Lone Star State.
