A40 Westway: Part closures on major London road as Tfl starts works in July

The A40 Westway, which connects the Wood Lane flyover to the west side of the Marylebone flyover, is undergoing a major refurbishment.

Some of the work includes replacing the ageing joints on the flyover structure – which was built in the 1960s, as well as resurfacing and waterproofing the carriageway.

The road, which is one of the busiest on TfL’s road network, is used by 90,000 vehicles every day.

From July, TfL will be replacing four joints, which provide support to slip roads to the A40 and will result in road closures.

TfL said it had decided to do the work at a time when its traffic studies showed traffic flows could be as much as 25% lower than usual.

This work will be undertaken in two separate phases:

From Sunday July 21 to Thursday August 22, the eastbound slip road from the Westway Roundabout and the A3220 West Cross Route southbound between the Westway Roundabout and the Holland Park Roundabout will be closed to all traffic

From Monday September 2 to mid-October 2024, the westbound on slip from the A3220 West Cross Route to the A40 Westway via the Westway Roundabout will be closed.  The A3220 West Cross Route from Holland Park Roundabout to the Westway Roundabout will also be closed to northbound traffic.

Work will be paused during the Notting Hill Carnival to minimise disruption.

Stuart Harvey, TfL's Chief Capital Officer, said: “We’re determined to ensure a safe and well-maintained road network can play a full role in enabling Londoners to travel across the capital. 

“These ageing 1960s structures are reaching the end of their serviceable life and road closures are essential if we are to ensure they can continue to serve Londoners for decades to come. We recognise that these closures will have a significant impact on people travelling in the area and are working hard to minimise disruption as much as possible, including by rescheduling other work and reviewing traffic signals. 

“I’d like to thank people in the area for their patience and would encourage everyone to plan ahead for any journeys in the area from July.”
