Tees Barrage Bridge, Cleveland
The Tees Barrage, designed to retain a constant water level and provide vehicular access from the A66 and A19, is a catalyst for the regeneration of Teesdale, 100ha of derelict land along the River Tees close to Stockton town centre. The bridge had to carry the highest standard loading specified by the Department of Transport (45 units of HB loading) so that future industrial development would not be restricted by the capacity of the bridge. The first design task was to determine the structure's behavior and the method of fabrication. A cast steel solution was developed, with the nodes cast separately and joined with tube-to-tube butt welds.
