TRANSPORT for London insist it is making 'good progress' on emergency work to strengthen the stricken A4 Flyover.
The four-lane stretch was dramtically shut days before Christmas last year after an inspection found safety fears.
It was closed for three weeks after engineers found 'serious structural defects' in the 50-year-old flyover which was blamed on saltwater corroding internal cables.
One lane in both directions was re-opened in mid-January but traffic continues to tailback into Hammersmith with 24/7 work taking place on the structure to get it re-opened in time for the summer Olympics.
And TfL say they have now removed 140 tonnes of concrete from the flyover as they step up their repair work and prepare to instal a new concrete base and new cables.
Isabel Dedring, deputy mayor for transport, said: “Our team are well aware of the major impact these works have in west London for road users and local people.
“That is they engineers are working 24 hours a day to get the job done. They are making good progress but, while the restrictions are in place, we will continue to have dedicated staff monitoring and managing the impact on traffic every hour of the day.”
Work to repair the five weakest spans of the 16 span flyover will be finished by the summer before TfL returns to strengthen the final 11 after the Olympic Games.
Garrett Emmerson, TFL chief operating officer for surface transport, said: “We are continuing to work round the clock to implement a long-term solution to restore the Hammersmith Flyover to full traffic capacity.
“With key enabling works now completed, work is now fully underway to install the new cabling system that will allow the structure to remain in use for many decades to come.”
Drivers are still advised to avoid the flyover. For traffic information visit www.tfl.gov.uk/trafficnews or follow @tfltrafficnews on Twitter.
