1/ Traffic lanes: reflects the prevailing number of lanes (excluding parking and turning lanes) carrying through traffic during the off-peak period. Access control: 'Full Access Control—preference has been given to through traffic movements by providing interchanges with selected public roads and by prohibiting direct driveway connections. Partial Access Control—preference has been given to through traffic movement. In addition to possible interchanges there may be some crossings at grade with public roads, but direct private driveway connections have been minimized. Some differences from other tables may be noted because these are estimated from sample data and do not include structures.

2/ Although the Interstate System is part of the National Highway System, its mileage is shown separately.

3/ Includes 3-lane roadways, one-way streets, undivided 4-lane highways, etc.; for Interstate, includes some 2-lane roadways.
