As work on the update of the motorways around the M40/M42 junction proceeds, Highways England is continuing to remove the traffic management – barriers, cones, construction equipment and some of the signage – from the network. To do this safely, for road users and their staff, they’ll need to temporarily close some lanes and carriageways overnight.
Upcoming week-night (between 9pm and 6am) closures until Friday 3 November 2023:
