Graham was awarded a £6.7m design and construct contract by Network Rail in January to replace the Tennison Road bridge. It will be the biggest bridge that has been replaced on the rail network in the southeast in the last decade.
The existing bridge, near Norwood Junction, has now been closed for its demolition. The new structure will be hydraulically pushed into place next Christmas and is scheduled to open for use in spring 2015. Its main span will be 3.5 metres wider than the existing bridge.
Tennison Road bridge was originally built around 1922 and crosses the London Bridge and Victoria lines.
Network Rail’s enhancements manager for the South East, Mike Smith, said: “The old structure is past its use-by date and this is a great opportunity for us and Croydon Council to put something better in its place. We have already built a temporary footbridge so there will still be pedestrian access across the railway and it will also allow vital services, such as electricity, gas and water, to continue undisrupted while the old bridge is demolished in the coming months."
