A road by any other number…
Ever wonder how highways and interstates get their numbering? If you’re anything like most of the population, you’ve never really thought about it…or you just assumed somebody was throwing numbers together for the heck of it.

There is a method to the apparent madness—this article from Greater Greater Washington outlines the strategy followed for the two-digit and three-digit highways and interstates in the U.S. Though of course there are exceptions, generally speaking, our highways and interstates are named based on a logical system.
The article is a good reminder that the little details we often take for granted in our everyday lives actually have to be carefully thought out and planned by somebody—in this case, transportation planners. What other small things do we take for granted?
