The Interstate System... simplified.

Chris Yates has a created a pretty cool map of the US Interstate System… as a subway map.

I just thought this was a nice example of how looking at an ordinary subject in a different, ordinary way creates an interesting solution. It doesn't help you figure out precise turns from San Antonio to Minneapolis, but it'll tell you what roads you'll be on for most of the time.

Thanks, as always, to BoingBoing.
