UK-based Network Rail has shortlisted three contractors to build a £50m flyover as part of the £2.3bn London Crossrail project.

Carillion, Morgan Sindall and Skanska have been shortlisted to construct a larger flyover at Stockley in Hillingdon to enable Crossrail services to operate to Heathrow.

Crossrail invited a tender for the flyover in May 2011, while the contract is expected to be awarded by October 2012.

In June 2010, Jacobs Engineering won the contract for the design of the Stockley flyover in the Heathrow Airport Junction area, which will provide a separate route for trains crossing the Great Western mainline.

Last week Network Rail had agreed to undertake new infrastructure enhancements and surface works on the Crossrail project. They will carry out above ground elements to ensure a smooth service to Maidenhead, Heathrow, Abbey Wood and Shenfield.

Including the flyover work, the company will complete modifications at 27 surface stations and build power infrastructure, such as overhead lines for the new rolling stock.

Crossrail trains will pass through 37 stations and run 118km from Maidenhead and Heathrow, via new twin-bore 21km tunnels below central London to Shenfield and Abbey Wood.

When Crossrail opens it will increase London’s rail-based transport network capacity by 10% and is also expected to offer the ability to travel directly to the West End, the City and Canary Wharf.

Network Rail will be undertaking major improvements planned for the Great Eastern and Great Western main lines, including improved stations, electrification, new signalling and the integration of the new Crossrail tunnels with the existing railway.
