Map of Roads in the Contiguous United States

From the featured website

According to cartographer Ben Fry the above is a map of twenty-six million road segments without any other features. It is something how a map of roads reveals so much about physical boundaries like mountains and rivers, not to mention cities and rural areas. The map with higher details of certain section can be viewed here. (Hat tip: Andrew Sullivan)

I liked this map but I questioned the validity of the data - it just didn't "look right." It appears that data from different counties or states varies on their definition of a road and it's inclusion in the data. Plus, showing all roads at the thickness of the line as it is on the map skews the hierarchy of the transportation network.
