Wearmouth Bridge

Wearmouth Bridge is a road bridge located in Sunderland, built in 1929 by the engineering firm Mott, Hay & Anderson, with GL Groves as the resident engineer and Sir W Arroll & Co. Ltd. from Glasgow as the contractor. The bridge features rock-faced sandstone abutments, a reinforced concrete road deck, and a steel superstructure with cast-iron footpath balustrades. It has a parabolic 3-pinned arch consisting of two ribs with a span of 375 feet, supported by spherical bearings at the hinges and K wind-bracing. This bridge was constructed on the site of an earlier iron bridge built in 1793, which was widened by Robert Stephenson in 1856. Some of the balustrade from the 1856 work has been incorporated into the new design, with additional panels made to match. The steps at the northeast include a cast-iron overthrow at the top and also incorporate elements from the 1856 structure.
