Repairs to the severe damage suffered by the Hammersmith flyover will ensure a longer term fix for the problems than previously thought, Transport for London’s (TfL’s) surface transport boss said today.
Addressing questions from the London Assembly Transport Committee, TfL managing director for surface transport Leon Daniels said that the repair plan had previously been understood to increase the lifespan of the structure by seven to 10 years, but it would now provide a “very long term” solution and increase the life of the flyover by “decades”.
The repairs involve restringing new steel cables throughout the bridge to replace the degraded cables that prompted the closure of the bridge before Christmas. However, the new cables will comprise a different type of steel that will not deteriorate as quickly as their predecessors, said Daniels, who added that these would also not be encased in concrete to ensure easier monitoring.
In addition, more recent inspection of the concrete of the structure revealed it was in “very good condition” which had meant the repairs would have a longer lifespan, he said.
The full cost of the repairs was still being calculated but were known to be running into tens of millions of pounds, said Daniels.
