This article describes the design of the new road bridge across the river thames at dartford, East of London, which is the first major bridge across the thames for over 50 years. The bridge and its associated works are estimated to cost 86 million, and are part of a 200 million scheme to relieve one of the worst bottlenecks on British motorways. A bridge was chosen, rather than additional road tunnels, because it could be completed at least a year earlier. The 4-lane bridge has a cable-stay design with a 450 m long main span, linked by 180 m side spans to the bridges's viaducts. It will have 2 pairs of twin nylon 137 m high and have a clearance of 57.5 m high water at its central point. The total length will be 2782 m, making it one of the longest bridges in Europe. Careful design checks are being carried out on the bridge, whose structure is designed to withstand the strongest known winds and impact from errant shipping; the use of halcrow computer graphics has enabled the designers to investigate every possible deflected form of the structure under load.
