A 'BOOMERANG' single masted single cable suspension bridge design has been lined up for a new pedestrian crossing of the Seine downstream of central Paris.
The bridge is believed to be the fi rst crossing of its type, with the deck signifi cantly cranked in plan. The design was produced by an Anglo-French team of Flint & Neill/Studio Bednarski/ Explorations Architecture.
When it opens in 2007 it will link the Sèvres bank with the Ile Seguin, site of a planned new arts complex.
Flint & Neill partner Ian Firth said the development of the shape of the deck was entirely driven by site constraints.
'One leg of the boomerang is the 80m main span across the Seine while the other forms the approach ramp running parallel with the river on the Sèvres bank.
'The central mast sits on top of a staircase and is stabilised by backstays to the staircase foundations. Although the steel box deck is supported only along one edge, its shape simplifies the loads in the structure.' Tuned mass dampers will be fi ed to stabilise the slender crossing. Construction is planned to start early next year, and total cost is estimated at £4M.
