Every single road in the U.S., in mind-boggling detail

Reddit user WestCoastBestCoast94 created this gorgeous map of the U.S. by picturing its roads and nothing else. (Click on it for a bigger version.)

The map reflects both the country's population density and its topography: The Northeast corridor between Boston and Washington, D.C. becomes one big mass of roads, while in very flat and/or less populated parts of the country, like the Midwest, the roads form clear grids. In the West you can see winding roads over the mountains and white spaces in the locations of Glacier National Park, Yellowstone, the Badlands, and other government-protected areas.
