Winner of a 2002 limited competition to design a new bridge over Tipner Lake on Portsmouth waterfront. In addition to an existing rudimentary concrete road bridge, and a new cycle / pedestrian bridge next to it, subject of this competition, a monorail bridge was to be built in the same location. Reacting to the risk of a confused jumble of bridges ( made worse by peculiar steel contraptions attached to the concrete bridge ) we proposed a low-key stress ribbon solution. The main span was approximately 84m which, the total length some 140m. Two alternative designs were proposed, one with the ribbon propped on a concrete arch and the other with the ribbon propped up on straight steel struts. The extensive inter-tidal mudflats around most parts of the harbour are rich in various invertebrates and worms and provide feeding grounds for a significant number of over-wintering wildfowl. These and other aspect of the Harbour have led to it being declared a Site of Special Scientific Interest (SSSI) and a Special Protection Area (SPA) & Ramsar site under European legislation. As a part of our commission, an environmental study was carried out to assess environmental implications of the project and to provide means for minimising potentially adverse impacts of the construction works.
