The NHPN currently contains 380,00 miles of roadway with 45,000 links and 28,500 nodes. Most links include a digitized chain of points showing roadway alignment derived from USGS 1:2M DLGs, generally accurate to approximately 1200 meters. Attribute detail on many roads includes administrative and functional class, and all roads will indicate sign route, length, and access control, among other characteristics. Inquiries about distribution should be directed to NESC at 312-972-7250. Technical queries to Bruce at 615-574-4419 or GTO@ORNLSTC on Bitnet.
