In Virginia, the Interstate Highway runs 68.64 miles (110.47 km) from the North Carolina state line near Bracey north to I-95 in Petersburg. I-85 passes through the eastern part of Southside Virginia, where it parallels U.S. Route 1 (US 1) from Petersburg, where the highway runs concurrently with US 460, to south of South Hill, where the highway intersects Southside`s major east–west highway, US 58. The Interstate Highway is the primary connection between the Richmond–Petersburg metropolitan area and the Research Triangle and other major metropolitan areas of North Carolina.
