Just fine the way they are; from dirt roads to rail roads to interstates

This is a great book that tells how the dirt roads have turned into the interstate and highway system that we have today.   It goes from the construction of the National Road to the railroads and the better roads for the bikes and cars that were invented.  It shows how as new inventions come along we have to accommodate them.

The pictures are wonderful and help to illustrate the material that is talked about.
