Check out national geographic, the make many kinds of maps, our local court house has a wall sized map of the united states from them. I also have the entire tahoe and el Dorado national forest on topographical map on a wall at my house, has every highway, road way, forest service road, dirt road, 4 by 4 trail, hiking path and horse trail on it. Even has every body of water named from lakes to irrigation ditches.

Another option, I am a AAA member and get free road maps, pm me your address and I will send you a map from them. They have all towns, highways freeways and interstates. Even has estimated travel times between major cities.
