 The two routes head into industrial areas with some trees and become closely parallel with Norfolk Southern's Norfolk District to the south.US 13/US 460 cross over the Southern Branch Elizabeth River on the Gilmerton Bridge, a vertical-lift bridge, with the railroad tracks crossing the river on a parallel drawbridge.Past the bridge, the road passes more industrial development and crosses a Norfolk and Portsmouth Belt Line Railroad line before coming to an interchange with SR 166, where US 460 splits from US 13 by heading north along SR 166.
