This is the world’s first ‘cranked’ stress ribbon bridge. The deck of this bridge consists of two concrete catenaries that were designed with a dogleg alignment with the angle between them at 25 degrees. The overall length of the bridge is 101.50 m ( river span 49.5 m + side span 37.5 m ). It appears to be the only UK concrete Millennium Bridge and the only one that was not a subject of design competition. The project was commenced in 1998 and completed in 2001. Among all the UK Millennium bridges it had the lowest cost of £2880 ( US$ 4420 ) per m2 of deck, including additional costs related to extreme flood conditions. Cezary M Bednarski’s practice acted as the lead consultant subcontracting structural engineering to Strasky Husty and Partners, with Flint & Neill as the checking engineers.
