The A40 Westway, which connects the Wood Lane flyover to the west side of the Marylebone flyover, will be closed eastbound from 10pm on Friday 26 November until 5am on Monday 29 November.
The road, which is used by more than 100,000 vehicles a day, will be closed in the eastbound directions on further weekends until March 2022, followed by closures in the westbound direction until the summer.
The closures will allow TfL contractors to carry out urgent maintenance work, including replacing the ageing joints on the flyover structure – which was built in the 1960s – as well as waterproofing the bridge deck.
Nick Fairholme, director of projects and programmes at TfL Surface, has said that the work will “allow the flyover to continue to be used safely” and has urged drivers to “plan ahead before their journeys”.
He said: “The A40 is key artery in west London and it’s vital that we ensure it is well maintained for the tens of thousands of people who use it each day. This essential work will replace an operationally critical roller shutter expansion joint and allow the flyover to continue to be used safely.
“Further work will be necessary given the age of the infrastructure, which we plan to carry out subject to the relevant funding. We’d urge people to plan ahead before their journeys, using alternative modes of transport where possible.”
Drivers travelling into London for Black Friday weekend sales are being advised to use alternative modes of travel where possible, with delays expected on local roads and the official diversion route due to increased traffic.
