Work to strengthen the Hammersmith Flyover will gather pace this weekend as resurfacing and waterproofing gets underway.
The busy road will be closed in one direction every until 4 August to allow contractors to carry out concrete deck repairs, resurfacing and waterproofing.
Transport for London is undertaking a huge programme of works on the 52-year-old flyover.
It appointed Costain last year to strengthen and refurbish 11 of the structure’s 16 spans. The other five were tackled by Amey during an emergency repair programme ahead of the London 2012 Olympics.
Dana Skelley, director of asset management at TfL, said: “Our work to complete vital maintenance works to the Hammersmith Flyover are progressing well.
“These weekend closures are required to allow us to complete the next section of works as quickly as possible. Our overriding focus when planning these weekend works has been to keep disruption to a minimum and we are ensuring that any affected drivers will have a clear, signed diversion route to help them complete their journey.”
Meanwhile, Hammersmith & Fulham Council is working on a plan to replace the flyover with a tunnel.
