This bridge carries the A1(M) motorway over the river; it was opened by Ernest Marples, the Minister of Transport, on 31 July 1961.
It consists of two separate structures, one for each carriageway, each having seven spans.
The longest span, formed from two 40-foot (12 m) cantilevers and a suspended central span of 100 feet (30 m), carries the motorway over the river at a height of 70 feet (21 m).
The total length of the structure is 760 feet (230 m), and it has a slight horizontal and vertical curve at its southern end.
Five riveted steel girders and a 9-inch (23 cm) composite concrete deck support each carriageway.
The bridge was one of the first to use rubber bearings, and the first to use bitumen membranes lined with copper to make the decks waterproof.
The design includes jacking points to compensate for mining subsidence.
