Identification_Information: Citation: Citation_Information: Originator: U.S. Geological Survey Publication_Date: 199911 Title: Major Roads of the United States Publication_Information: Publication_Place: Reston, Virginia Publisher: U.S. Geological Survey Online_Linkage: Description: Abstract: This data set portrays the major roads in the United States, Puerto Rico, and the U.S. Virgin Islands. The file was produced by joining the individual State roads layers from the 1:2,000,000-scale Digital Line Graph (DLG) data produced by the USGS. This is a revised version of the March 1999 data set. Purpose: These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the U.S. Geological Survey in the use of these data.

The files were updated and the Arc/INFO software command DLGARC was used to convert the State DLG optional-format files to Arc/INFO coverages. The individual State coverages were then merged together using the Arc/INFO command APPEND.
