The North Run Bridge serves U.S. 1. This interstate road was given its numerical designation by the federal government in 1925 to reflect its significance as the major highway from Maine to Florida, designed to tie together the major cities of the East Coast. When the North Run Bridge was built, the road was only two lanes wide in this vicinity. The bridge is of reinforced concrete construction, with three Gothic-arched spans. It rests on concrete abutments with span arches that repeat the Gothic motif. The North Run Bridge is a good example of a type of bridge that is becoming increasingly rare on Virginia's highways.
