Background Information
Sample map Sample Map
A road is an open way for the passage of vehicles. Major roads include Interstate routes, U.S. routes, State routes, and other large roads. The U.S. Geological Survey (USGS) collects information on major roads to support the production of base maps for the United States. The Federal Highway Administration (FHWA) of the U.S. Department of Transportation is responsible for overseeing highways in the United States, which includes promoting safety, providing technical expertise, developing regulations, and providing development and maintenance of Federal roads. Information on the history of major roads in the United States can be found on the FHWA highway history page.

This map layer shows the major roads and ferry crossings in the United States, Puerto Rico, and the U.S. Virgin Islands that can be represented at a map scale of 1:2,000,000 (1 inch on a map at that scale equals about 31.6 miles on the land surface). We also produced a map layer of Major Roads as of 2012 at a scale of 1:1,000,000. Most local streets and small roads cannot be portrayed at these scales. Descriptive information includes the route number and the road type. This map layer was compiled by the National Atlas of the United States.

In cooperation with national mapping programs in Canada and Mexico, we also produce a map layer of major roads across North America at a scale of 1:10,000,000.
