There are to be extended closures of slipways off the A40 on the Westway between the Wood Lane and Marylebone flyovers through to the autumn.

Transport for London (TfL) has announced the planned critical safety maintenance work which will require slip road and directional road closures from July until mid-October with the most impactful closures taking place during the summer holidays.

It is warning that planned diversion routes will be extremely busy and that this is just the first phase of work on the road.

The A40 Westway is one of London’s busiest roads, carrying around 90,000 vehicles a day. The structures, which carry the Wood Lane flyover to the Marylebone flyover, date back to 1969 and TfL says they are reaching the end of their serviceable life, requiring vital maintenance.

From Sunday 21 July to Thursday 22 August, 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 2 September to mid-October, 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 is being paused during the Notting Hill Carnival.

TfL says it will be putting a comprehensive traffic signal strategy in place to try and keep traffic moving as smoothly as possible.

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.”
