Swedish firm Skanska has won a $94m (SEK660m) contract from UK rail operator Network Rail to build a railway viaduct in the south east of London.

The viaduct is part of the operator’s Thameslink rail programme and involves building a 400m-long viaduct over the Borough Market food market in south-east London as well as demolishing works.

Work will begin immediately and is scheduled to finish in August 2012.

The company had previously assisted Network Rail in planning and developing the project.
