Concast supplying precast to the £50m Stockley flyover for Network Rail

The new flyover at Stockley in Hillingdon, allows Crossrail services to operate to and from Heathrow. The flyover was built at the very busy Heathrow Airport Junction area, which services trains to and from Heathrow as well as along the Great Western Main Line (GWML). A new single track viaduct for all trains from Heathrow towards London was built, ensuring that trains will be able to join the branch to Heathrow without delay - or being delayed by - fast trains to the west.

Carillion won the contract to build the flyover, which was designed by Jacobs Engineering, in a deal worth up to £50 million. Concast have now supplied over 3,000lm of bespoke precast units to the project, with some individual units weighing up to 50T.

Due to the close proximity to live rail lines, installation had to be carefully planned to minimize commuter disruption, including deliveries on Christmas day.
