A40 Acton Bridges

The installation of the first new bridge beams at Wales Farm Road Bridge was a major project milestone in October 2006

Transport for London (TfL) is currently carrying out work to replace the two A40 Western Avenue bridges over the railway lines at Wales Farm Road and Perryn Road in Acton. This is a challenging engineering project, involving a complex construction sequence in order to maintain normal traffic and rail operations throughout the project, as well as ensuring safety at all times.

New bridge construction continues

18 July 2008

Further sections of the existing bridges have been dismantled during recent months and construction of the next new bridge sections is now progressing.

New bridge beams, measuring up to 40 metres long, have been installed at Perryn Road Bridge and this is also underway at Wales Farm Road Bridge. The beams are prefabricated off-site and lifted in by crane at night when trains have stopped running.

At Perryn Road Bridge, the eastern half of the new bridge deck is being built, in preparation for the next traffic switch in August. At Wales Farm Road Bridge, construction of the western half of the new bridge is underway. Further details can be found in the latest edition of the project newsletter, which can be downloaded from the newsletter page.

Further information about the project can be viewed on this website, which will be updated regularly as the work progresses.

Why is this work necessary?

We need to undertake this major construction project because the bridges were built during the late 1920s and were not designed to manage today's volumes of A40 traffic - over 100,000 vehicles a day. The new bridges will also ensure the safety of the railway tracks below that handle all rail networks in and out of Paddington, including the Heathrow Express and First Great Western - over 800 trains, transporting 145,000 passengers daily.

Replacing the bridges also means we can improve the highway layout over the bridges as well as creating access and crossing improvements for pedestrians, cyclists and people with disabilities.
