Footage has been released of a critical part of a project to ensure Crossrail and Heathrow Express services can join the Great Western Main Line swiftly as they head into London.
The video shows the final concrete beam lifted into place to support construction of a second ramp at the Stockley Flyover in west London.
Carillion is building the flyover for Network Rail as part of the Crossrail programme. A total of 146 beams were installed to support the second ramp, each weighing about 40t.
Crossrail surface director Matthew White said: “Putting in place so many heavy beams so close to a running railway is no mean feat.
“Once the flyover is fully open it will help to provide great links between Heathrow and central London and contribute to London’s continued presence as a modern world-class city.”
Network Rail Crossrail programme director Matthew Steele added: “To complete this element of the work six weeks ahead of schedule, safely and with minimal impact on passengers is a great achievement. There is still a lot of work to be done, and we will now focus on completing the second section of the flyover, ready for Heathrow Express services.”
