Major milestone reached in the construction of Stockley flyover
The final concrete beam to support the construction of a second ramp at the huge Stockley Flyover in west London has been lifted into place as Network Rail continues to construct the flyover as part of the Crossrail programme.
The first section of the flyover came into use for Heathrow Connect services at the end of 2014 and a second ramp is now being constructed so that it can also be used by Heathrow Express trains.
A total of 146 beams were installed to support the second ramp, each weighing around 40 tonnes – more than three times the weight of a London bus. More than 5,000 tonnes of precast concrete has been installed since the first beam was lifted in May 2015. The work was carried out around the operating railway and took place at night in order to avoid disruption to train services and was completed six weeks ahead of schedule.
The new flyover in Stockley, Hillingdon, will ensure that Crossrail and Heathrow Express services heading towards central London will be able to join the Great Western Main Line without delaying, or being delayed, by other trains using the route.
Matthew White, Surface Director at Crossrail 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.”
Matthew Steele, Crossrail Programme Director at Network Rail said: “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.”
When the route to the west of London fully opens in 2019, TfL-run Crossrail will significantly improve links between Heathrow and the capital’s main commercial and financial districts – the West End, the City and Canary Wharf. Passengers will be able to catch one train all the way through central London from Heathrow, reaching Bond Street in 26 minutes and Canary Wharf in 40 minutes.
