Highways England need to carry out works on the M4. The section of the A4 which runs underneath it will be affected.

  • Single lane closures will be in place Monday to Friday between 05:00 and 22:00
  • The road will be fully closed between 22:00 and 05:00 each night
  • Total weekend closures will be in place between 13 October and 19 November from 22:00 Friday to 05:00 Monday
  • Follow signs for diversion routes overnight and at weekends
  • Freight journeys may be best made overnight when traffic volumes are lower - but will need to be rerouted to avoid the A4 between Ealing Road and Clayponds Avenue

While these closures are in place, surrounding roads will be busier, and there may be delays to your journey.

If you have any questions about the works, please contact info@highwaysengland.co.uk or call 0300 123 5000.

Driving

The diversion routes will be:

  • Eastbound traffic - Ealing Road, Uxbridge Road and the A406
  • Westbound traffic - M4

While these closures are in place, surrounding roads will be busier. Expect delays to your journey, plan ahead and leave more time.

For access to key areas in west London, such as Heathrow Airport, your journey may be quicker using rail or underground services, such as the Piccadilly Line.

Buses

The H91 bus route that uses the A4 through the works area will continue to have access. The bus stops between Clayponds Avenue and Ealing Road will be suspended.

  • Eastbound - bus stop BV (Clayponds Avenue)
  • Westbound - bus stops BZ (Clayponds Avenue) and BB (Ealing Road)

Surrounding roads will be busier, which is likely to affect other bus routes in the area.

Please allow more time for your journey. To find out how your bus may be affected visit tfl.gov.uk/bus/status and follow @TfLBusAlerts on Twitter for the latest bus updates.
