Cameron Booth, inspired by Harry Beck’s famous London underground map, created this interpretation of the US Interstate system.
As a design exercise and visually I think it looks fantastic. It also shows off beautifully the basic lines of the highway system design, for example the way interstate 80 cuts straight across the country from coast to coast.
I’m not sure how usable it is as an actual map though, I had a hard time finding Los Angeles, even though it is the second largest city in the US.
