Engineers have inserted 100 cameras into the Hammersmith flyover to further assess cable damage as TfL staff insisted the structure will reopen in time for the Olympics.
Investigations are expected to continue for a further week before engineers can consider reopening the structure to light traffic.
He said: “I want to reassure the thousands of motorists and local people who are suffering traffic hell that the flyover will not be closed one day longer than necessary.
“Safety has to be the number one priority but Transport for London will reopen this vital stretch of road as soon as they are able to do so.”
“One thing I can assure Londoners of is that a plan is being finalised within the next few days and work is already beginning on strengthening the flyover so that it is fully operational well ahead of the 2012 Games.”
TfL stated that the damage to the flyover, built in 1962, has been caused by water ingress, including salt water due to grit laid during the winter months, which has corroded and weakened the cables which help support the flyover.
TfL’s managing director of surface transport, Leon Daniels said: “Our team continues to work night and day alongside the world’s leading structural engineers to fully understand the extent of the flyover’s structural problems.
“A solution which will allow the flyover to be fully open to traffic before the Olympics is now being implemented and we will re-open the flyover to traffic as soon as it is safe to do so.
A team of 80 TfL engineers, contractors from Amey, and leading structural engineering experts have been working nonstop on site and within the structure throughout the Christmas and New Year period.
A series of measures have been put in place to provide temporary traffic solutions:
Traffic police rapid response units on placed on permanent standby in the area
Local traffic diversions, along with Variable Messaging Signs
The re-phasing of hundreds of traffic signals in the area to reduce disruption as much as possible and ease traffic flow
The cancellation of any non urgent roadworks in the local area and a daily review of whether other works should be suspended. Works cancelled have included previously planned works at Earl’s Court Road, Cromwell Road and the Westway
The creation of an extra lane on Talgarth Road to help minimise the impact of the closure
Close liaison with the relevant local authorities to keep local people, businesses and organisations informed of the ongoing work taking place
Plans to divert traffic from the M4 to other routes if necessary
Working with boroughs on the efficient management of their roads to help cope with the closure
