State Route 401 is a primary state highway in the U.S. state of Virginia. Known as Van Dorn Street, the state highway runs 2.61 miles (4.20 km) from SR 613 at the south city limit of the independent city of Alexandria north to SR 420 within Alexandria.

State Route 613 in Fairfax County, Virginia is a secondary state highway. The designation includes several distinct suburban surface routes within the county. These routes were once mostly connected, but changes in road alignment, new road construction, and annexations by the independent city of Alexandria have separated them. These routes are signed only sporadically as 613 and local residents usually refer to these routes by their names.
