WSP Group has been chosen to design the redevelopment of London Bridge Station in Southwark, London, England.
The 16-month contract will see WSP take the current scheme for the station building through outline design to the build phase due to begin late in 2012.
The station will be rebuilt to create more space for passengers with additional concourse space below the platforms at street level.
The track layout will also be changed and the signalling renewed to accommodate metro-frequency services on the Thameslink routes through the station.
This major upgrade will enable the route to combat congestion at the station, and provide greater journey opportunities for passengers on Thameslink services.
The scheme is being delivered for Network Rail and is a major part of the £5.5bn ($8.59bn) Thameslink improvement project.
London-based Mace will serve as the contractor for the project and Jacobs Engineering will complete the outline design of the railway systems elements including track, signalling, telecoms and associated power supplies.
