Bow String Bridge is a 55 metre long reinforced concrete through girder bridge; it spans the River Calder near Wakefield, England. The bridge was initially designed to carry both road and rail traffic, the railway lines being set into the 2.6 metre wide carriageway.
Steel reinforcement was added to the lower chord member in 1997 to temporary strengthen the bridge to carry large refuse disposal trucks.
