Skanska delivered the construction of the Bermondsey Dive Under and associated structure strengthening works for Network Rail as part of the Thameslink development programme.
A major programme objective was to provide additional Thameslink services through central London. Two pieces of infrastructure were needed to reduce delays outside London Bridge.
One was the new viaduct at Borough Market, completed by Skanska in 2012. This provides two additional tracks at this critical pinch point. The other was a grade-separated junction between New Cross/New Cross Gate and London Bridge station, known as Bermondsey Dive-Under.
Under the contract, Skanska was responsible for the design and construction of the Dive-Under, formed of 11 new interconnected structures, along the line of existing operational rail viaducts.
Skanska also carried out associated strengthening works to a number of bridge structures and brick arches along the route. Wherever possible, reusing existing structures to minimise disruption and reduce waste.
