USA Road Map

The USA Road Map shows national capital, state capitals and highway numbers along with extensive road and highway networks. The USA Road Map essentially combines two extensive road and highway networks of US, namely the Federal Interstate Highway and the regional US Highway Map. These two main road-highway networks are central to the overall American surface transportation network, which, however, also includes two other road-highway systems, namely the State Highways and the County Highways.

However, the differences in the four levels in the entire US road-highway transportation network are more on administrative and operational lines than functional. For instance, some roads or highway in the State Highway network may be so heavily traveled that they match the Federal Interstate Expressways in their standards of quality and maintenance.
