The A40 Greenford flyover has been closed over the entire Christmas and New Year period to allow Transport for London engineers to carry out urgent repairs to its expansion joints.
The flyover was fully closed in both directions from 10pm on Monday 24 December and remained closed until Thursday 3 January.
TfL has had to replace expansion joints across and at both ends of the Greenford Roundabout Flyover and carry out resurfacing around the new joints.
It is the third London flyover to be closed for urgent repairs in a year, after defects were found in Hammersmith flyover last December and in the Highways Agency’s Boston Manor viaduct shortly before last year’s Olympics.
According to a TfL spokesman the work was planned over the Christmas and New Year period to minimise disruption. Traffic was diverted via the roundabout beneath the flyover with a wider diversion route in place for traffic wanting to access the A406 North Circular Road. The A40 was fully reopened in the early hours of 3 January, several hours ahead of TfL’s 5am target.
