Piling is under way for the new Hungerford footbridge across the River Thames in central London. The £26M bridge is being built by a Costain/Norwest Holst joint venture. About 50, up to 1.6m diameter bored piles are being installed up to 40m into the river bed from a Taylor Woodrow jack-up barge. More than 50 smaller piles will form temporary works and a casting yard for the six span precast, prestressed concrete launched decks. Design and construction methods had to be vetted by London Underground, Railtrack and the Environment Agency before piling could begin because river walls, active rail lines and two underground lines cross under the river at this point, some as close as 10m to the works. The scheme, managed by consultant WSP, will create a cable-stayed footway on either side of the railway crossing into Charing Cross station.
