A4 Hammersmith flyover stays closed for tests on defect
07:58 03 January 2012
A flyover on one of the busiest routes into London remains closed this week due to a serious structural defect.
The Hammersmith Flyover on the A4 in west London was closed on December 23 so assessment of the structure could take place.
The flyover, used by drivers coming off the M4 from Heathrow Airport into central London, has remained closed to traffic until further tests have been completed, Transport for London said.
TfL said it was ““working as fast as we can” but the flyover would not reopen this week.
The cables of the flyover, built in the 1960s, have become corroded and weakened by water ingress.
Local traffic diversions are in place and drivers have been advised to avoid the area.
A statement from TfL said engineers checking the condition of the internal cables which hold the spans of the concrete structure in place had been monitoring the flyover over the past two years.
It was thought the structure had a number of years before major repair work would be needed.
Recent results showed repair work was needed earlier than anticipated but further inspections identified additional technical problems.
