Major maintenance work is to be carried out on the important A40 Westway between the A40 Northern Roundabout and the Marylebone Road in London.

Transport for London says the essential work will take place at weekends from the end of November through to Summer 2022 with the first closure in the eastbound direction to take place this weekend.

The A40 Westway is one of the busiest strategic routes on TfL’s road network, normally used by nearly 100,000 vehicles a day.

TfL says to keep the A40 Westway and surrounding road network running safely and reliably, the works and associated road closures have been planned to avoid the busiest periods, with directional closures taking place at weekends.

The work, which is the first and most urgent of a range of works required on the flyover, will see some of the flyover’s joints, which span the gaps between the concrete sections of the structure, replaced to ensure they remain safe.

The bridge deck will also be waterproofed to help protect the structure for years to come. To minimise the impact on nearby residents, TfL’s contractor Costain will be using a special low-vibration method of concrete removal called hydro-demolition, which uses a high-pressure water jet to break down the concrete.

TfL says this is far quieter than traditional methods of concrete removal.

The A40 Westway will be closed eastbound from Friday 26 November 22:00 to Monday 29 November 05:00. Those travelling westbound will be able to use the A40 Westway as normal.

People using the A40 Westway to travel into London from the west are advised that it will be closed during this period. Local routes and the official diversion route are expected to be busy with journeys likely to be delayed.
