Summary
Description
This map layer includes Global Map data showing the major roads in the United States, Puerto Rico, and the U.S. Virgin Islands. The data are a modified version of the National Atlas of the United States 1:1,000,000-Scale Major Roads of the United States; that file was produced by joining the individual State roads layers from the National Highway Planning Network (NHPN), Geographic Data Technology (GDT) Dynamap, and TIGER/Line files.
