U.S. Route 1 (US 1) is a major north–south U.S. Route that serves the East Coast of the United States. In the U.S. state of Virginia, US 1 runs north–south through South Hill, Petersburg, Richmond, Fredericksburg, and Alexandria on its way from North Carolina to the 14th Street bridges into the District of Columbia. It is completely paralleled by Interstate Highways in Virginia—Interstate 85 (I-85) south of Petersburg, I-95 north to Alexandria, and I-395 into the District of Columbia—and now serves mainly local traffic. At its north end, on the approach to the 14th Street bridges, US 1 is concurrent with I-395; the rest of US 1 is on surface roads.
