Hammersmith Flyover to close for repairs

Wednesday April 18, 2012

Transport for London (TfL) will begin installing new tensioning cables inside Hammersmith Flyover this week, as part of its ongoing work to fully reopen the structure to all traffic in June.

The works mean that the flyover will be closed overnight, every night, from today (Wednesday, April 18) until Monday (April 30). It will close from 10pm until 6am every night, with the exception of tonight when it closes at 11pm, and Saturdays when the flyover will open later at 10am and close at 6pm.

The structure will also be closed for the next two Sundays, April 22 and 29, all day until 5pm.

During the closures, traffic will be diverted around the Hammersmith gyratory system and advance warning signs will be put up on local approaching roads. Motorists are advised to avoid the area and use alternative routes or public transport, where possible.

The closures will allow TfL to undertake essential works to install new tensioning cables to replace old support cables inside the bridge that have corroded. The new cables are surrounded by wax oil to prevent deterioration, and allow inspection and replacement if required in the future.

The works, which began in January, have seen around 200m of the central reservation along the flyover removed, new structural slab and concrete barriers installed, as well as tailored anchorages for the new cables inside the structure.

Garrett Emmerson, chief operating officer for surface transport at TfL, said: “We are now approaching a critical phase in our race to reopen the Hammersmith Flyover as quickly as possible. This will require a number of overnight and Sunday daytime closures to ensure that the works are carried out safely and correctly.

“I would once again like to apologise for the inconvenience that this work is causing and reassure Londoners that we are continuing to work around the clock to complete these vital works as quickly as possible.”

As a contingency, TfL may need to close the flyover for more night-time closures and another Sunday day-time closure in late May, but will review the situation after the upcoming work.

TfL says that work to strengthen the five weakest spans of the 16 spans in the structure will be completed in June 2012, ahead of the London 2012 Games, and allow the bridge to reopen to full traffic. TfL will carry out further repairs to the flyover during 2013 to strengthen the remaining spans.
