Highways
VDOT operates the third largest state-maintained highway system in the country, just behind North Carolina and Texas.
The 59,672-mile state-maintained system is divided into these categories:
- Interstate: 1,119 miles of four-to-ten lane highways that connect states and major cities
- Primary: 8,046 miles of two-to-six-lane roads that connect cities and towns with each other and with interstates
- Secondary: 50,195 miles of local connector or county roads. These generally are numbered 600 and above. Arlington and Henrico counties maintain their own county roads.
- Frontage: 312 miles of frontage roads
A separate system includes 11,900 miles of urban streets, maintained by cities and towns with the help of state funds. Virginia's cities are independent of its counties. Henrico County (1,415 miles) and Arlington County (406 miles) maintain their own roads with VDOT funds. There is an additional 59 miles of toll roads maintained by others.
For more information, you can read how roads are funded, how a road gets built, how a road qualifies for state maintenance, and look at current and upcoming projects.
