The Tees Barrage at Stockton-on-Tees stabilises the water level at a previously tidal part of the river, and provides watersport facilities with a watersports centre nearby. Commissioned by Teesside Development Corporation it took four years to build at a cost of £50 million and is intended to attract investment by making this part of the Tees cleaner and more attractive. Much development has certainly taken place since its opening, helping the regeneration of Teesside.
There is a main road bridge of 160 metres with 8 spans, with 4 of 17.5 metres each on the bridge itself. There is also a lower footbridge for walkers and cyclists which can be lifted by means of a hydraulic jack. The design and build contractor was Tarmac Construction's Civil Engineering Division. The barrage is managed by British Waterways. There is a fish ladder allowing fish to pass upstream although complaints have been made that its small size delays the fish and so allows attacks from seals. This is, however, an attractive addition to the Tees.
