UK CONSULTANT Halcrow is part of the winning design team for an 8.8km long bridge in Shanghai across the Yangtse river estuary.
The Chongming North Bridge will be the final link in a chain to connect mainland China and the 1,041km2 Chongming island - the country's third largest - which is set to be the scene of major new development.
Halcrow won the commission in partnership with Shanghai Municipal Engineering Design Institute (SMEDI) and Danish Consultant COWI.
The new bridge is part of Shanghai's largest ever urban project which involves constructing the bridge, an elevated highway and a tunnel connection Changxing and Chongming islands to the city. The Yuan12.3bn (£850M), 25km route will cut travelling time to Chongming from a two hour ferry ride to 30 minutes.
Most of the bridge will be built as a viaduct but there will be a 730m main span cable stay section over the main navigational channel.
Halcrow is also part of the design team for the 9km tunnel section, along with Shanghai Tunnel Engineering and Rail Transit Design and Research Institute, Parsons Brinckerhoff (Asia) and the Third Harbour Engineering Investigation and Design Institute.
The 13.8m internal, 15.2m external diameter tunnel to be bored through the soft ground by a slurry balanced TBM will be the largest of its type in the world, Halcrow says.
