U.S. Major Roads provides an invaluable reference and cartographic layer that make it easy to identify areas in other data sets. U.S. Major Roads overlays accurately on streets and other boundary data.
Attribute and geospatial data
GDT maintains Highways data from its internal, master database that includes nationwide street and road network data and Census data. Technicians then begin a state-by-state editing process that includes (but is not limited to): Eliminating errant segments–Occasionally, we have discovered cases where the highway, as digitized, deviates considerably from the actual course. In these cases, GDT technicians digitize the correct segments and delete the erroneous ones. Feature reclassification–Another drawback to TIGER-derived files was their feature classification codes (FCCs). These codes were an attempt to classify streets and roads based on maintenance, a procedure that varied dramatically in different geographic areas. To correct this problem and create a consistent nationwide highway system, GDT reclassified almost every street and road in the nation based on its use. Highways names are applied according to a layered hierarchy. Where a highway segment has more than one name, the higher-level name will always be used, and always in this order: Interstates, then U.S. Highways, State Highways and Local Names. The data GDT uses to define highways and ensure completeness is culled from the following sources: · Dwight D. Eisenhower System of Interstate and Defense Highways. Published by the U.S. Department of Transportation, Federal Highway Administration. Lists all interstates. · U.S. Numbered Highways. Published by the American Association of State Highway and Transportation Officers. Lists all state and U.S. highways. · State highway maps. Highway maps from state travel and tourism agencies and/or state departments of transportation.
The following steps were performed by ESRI: Extracted data set from GDT Dynamap/2000 v. 12.0. Removed unneeded attributes and Puerto Rico features. Converted Hawaii to North American Datum of 1983 (NAD83). Generalized to a tolerance of 0.00001 decimal degrees. Unsplit features based on concatenation of several attributes. Removed tiny and isolated ramp features less than 0.0005 decimal degrees in length. Recalculated LENGTH values. Created ArcView legend file (.avl), ArcGIS™ layer file (.lyr) file, projection file (.prj), and spatial indices.

The geospatial part of this data set was extracted from the Census Version TIGER/Line® files (CD–ROM edition). To improve the accuracy, GDT ran a process against the entire nationwide database. The data set was generalized to a tolerance of 0.00001 decimal degrees. The positional accuracy is unknown.
After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
No duplicate features are present.
