Motorists travelling in the Midlands should prepare for significant travel disruptions this September due to a full weekend closure of a section of the M42 east of Birmingham. The motorway will be closed in both directions between junctions 6 and 9 from 9pm on Friday, 18 September, until 5am on Monday, 21 September.
This closure accommodates essential HS2 works, including the final installation of motorway beams and viaduct construction. Additionally, the closure encompasses vital links including the M6 J4a southbound connection to the M42, the M6 northbound J3a link to the M6 Toll T1, as well as the M6 Toll southbound from T2.
During this time, National Highways will also be demolishing the ageing Bickenhill Bridge at Junction 6. Inspections conducted in November 2025 revealed significant structural deterioration, including concrete damage and corrosion to steel reinforcements, leading to earlier lane closures and weight restrictions. The bridge was fully closed in July and is now scheduled for complete removal.

National Highways has stated that repairing the bridge is not viable. The demolition will use specialist equipment in a carefully controlled process, prioritising safety at all times. The bridge remains safe for vehicles travelling underneath on the M42.
To assist drivers, fully signed diversion routes will be in place via the A446 Lichfield Road and Stonebridge Road, joining the A45 Coventry Road. Drivers are advised to allow extra time for journeys, particularly those heading to Birmingham Airport, Birmingham International Train Station, and the National Exhibition Centre (NEC), and to follow the official diversion routes rather than relying on satellite navigation systems.
While restrictions at Junction 6 will continue after the bridge demolition, access to the airport, train station, and NEC will remain open. National Highways will closely monitor traffic flow and collaborate with local partners to minimise disruption.
Plans are underway to install a temporary bridge at the junction until a permanent replacement can be constructed. Existing diversions have been reported to be functioning with minimal disruption in the interim.
