Engineering contractor Costain has been appointed to Transport for London’s ECI Framework, which includes the work on strengthening the Hammersmith flyover.
Work will start immediately, with the framework running for four years, and is likely to involve strengthening the flyover using post-tensioning, replacing bearings, waterproofing and resurfacing the deck, and replacing the drainage.
The flyover closed in late 2011, with a Transport for London investigating a “serious structural defect”. Some have called for its replacement with a tunnelled alternative, with the council supporting the concept.
Leader of Hammersmith & Fulham Council, Cllr Nicholas Botterill, said: “We know that vital repairs are necessary to the flyover but this needs to be the last time TfL spends a huge amount of taxpayers’ money on maintaining this monstrosity. Any other cash set aside for future work to the flyover needs instead to be pumped into making the flyunder a reality.
“A new tunnel solution would dramatically improve the quality of life for thousands of west Londoners and link the riverfront with Hammersmith town centre for the first time since the 60s.”
Garrett Emmerson, chief operating officer for surface transport at TfL, said: “We understand that H&F Council is keen to look at proposals to replace the Hammersmith flyover in more detail. We have discussed this with the borough recently and offered support to them in putting their case together for this project. Any plan to replace the flyover would need to be fully assessed, justified and funded through the wider redevelopment of the area.”
