Transport for London is set to close parts of the busy A40 starting this summer as repairs are made to the Westway slipways.
Although TfL has pledged to minimise disruption, the Westway carries 90,000 vehicles a day and closures will affect motorists in west London.
What's the problem?
The pillars and supports that carry the Wood Lane flyover through to the Marylebone flyover date back to 1969, and after more than half a century of traffic pounding the reinforced concrete is coming towards the end of its useful life.
So in July, engineers will be replacing four joints which support the A40 slip roads.
TfL has deliberately chosen the summer holidays as traffic levels dip by 25 per cent. But work will go on until mid-October. Further phases are planned during winter, and in coming years.
Closure details
From Sunday 21 July until Thursday 22 August, the eastbound slip road from Westway roundabout, and the A3220 southbound route between Westway roundabout and Holland Park roundabout, will be shut completely.
Then from Monday 2 September until the middle of October, the westbound lanes of the slip road from the A3220 West Cross Route to the A40 Westway, via the Westway roundabout, will be closed. The West Cross Route from Holland Park roundabout to Westway roundabout will also be shut off then to northbound traffic.
Work will pause during the Notting Hill Carnival weekend of 25 and 26 August.
"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," said Stuart Harvey from TfL. "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."
