The A40 Westway has reopened to traffic on the evening of 21 April, bringing an end to a month-long closure that began on 20 March to allow for critical infrastructure repairs.
Transport officials confirmed the route is now fully operational after essential work was completed on key structural components linking the Westway and the Marylebone Flyover. The repairs focused on replacing expansion joints that had reached the end of their service life—vital elements that allow the elevated roadway to safely adjust to temperature changes and constant vehicle movement.
The closure, while disruptive, enabled engineers to carry out complex and highly specialised work safely and efficiently. In addition to the joint replacements, crews took the opportunity to resurface more than a kilometre of carriageway in both directions and perform drainage maintenance aimed at preventing future issues.
Handling up to 96,000 vehicles daily, the A40 Westway is one of the capital’s busiest routes, making the timely completion of the project a priority. Transport authorities said the work was carefully scheduled to minimise long-term disruption while ensuring the reliability of the road network.
Although the main route has now reopened, further improvement works are planned over the coming weeks. These will take place across four weekends starting 24 April and are expected to conclude in June—earlier than originally scheduled. Officials say these additional works will be smaller in scale and more localised, reducing the impact on road users.
Transport leaders thanked drivers and local communities for their patience during the closure, emphasising that the upgrades are essential to maintaining a safe and dependable transport network.
