A40 Westway: TfL to begin London road renovation in 2024

The Westway, which is one of the busiest on TfL’s road network, is used by almost 100,000 vehicles every day.

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

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, one of the busiest on TfL’s road network, is used by almost 100,000 vehicles every day.

TfL says the maintenance work will keep the A40 Westway and surrounding road network running safely and reliably in the future.

It says lane restrictions and some partial closures of the A40 at night and on some weekends will be needed to complete the work.

What work still needs to be done?

Subject to funding and access, in 2024, the work will begin to:

  • Replace 10 tooth/comb expansion joints along the A40 Westway and at Marylebone flyover
  • Resurface and waterproof the carriageway where expansion joints are replaced
  • Replace the metal work on inspection access hatches in the carriageway
  • Target repairs to the Westway drainage
  • Target concrete repairs in areas under the Westway

What work has been done so far?

In 2022, TfL completed the installation of the new roller shutter expansion joint across the full width of the eastbound and westbound carriageways of the A40 Westway.

Nick Fairholme, director of projects and programmes at TfL Surface, said in November 2021: “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.”
