IT'S caused months of misery, but now the end is in sight as the Hammersmith Flyover is set to fully re-open at the end of the month.
Transport for London (TfL) has been working 24/7 to get the four-lane flyover repaired in time for the Olympic Games after it was dramatically shut days before Christmas last year.
It was closed for three weeks after engineers found 'serious structural defects' in the 50-year-old structure blamed on saltwater corroding internal cables.
One lane was re-opened in both directions in mid-January for light traffic but the partial closure has caused tailbacks and traffic congestion in and around Hammersmith.
Now TfL has announced that vital repair work on the structure will be completed on Wednesday, May 30 and will re-open to all traffic.
Until then there will be two weeks of overnight closures beginning tonight (15) to carry out the final elements of the work.
Between 10pm and 6am, motorists will be diverted around the Hammersmith gyratory system.
Chief operating officer for surface transport at TfL, Garrett Emmerson, said: "The Hammersmith Flyover is a vital artery for London and our engineers have been working non stop since December to deliver a solution which allows us to fully re-open the flyover to all traffic as quickly as possible.
"The final phase of works to prepare the carriageway for full re-opening is now well underway and are scheduled to be completed by May 30; well ahead of the London 2012 Olympic Games."
There has been around 22km of new cables installed in the structure which are surrounded by wax oil to prevent deterioration and allow inspection and replacement if required in the future.
Earlier this year there had been serious concerns as to whether the stricken A4 Flyover would be repaired in time for the Olympic Games.
