M42 to close again this weekend for HS2 works
By James Smith 23rd Jul 2026
HS2's second weekend-long closure of the M42 is scheduled for this weekend.
The motorway was shut in June to allow HS2 engineers to install beams for the new box structure near Birmingham Business Park.
The next closure will be held from 24 to 27 July.
The road will be closed between junctions 5a and nine northbound and from junctions seven to six southbound.
There will also be a closure for the M6 northbound J3a link to M6 Toll T1 and M6 Toll southbound at T2.
This closure will enable the Water Orton viaduct to be installed and for more beam works to take place.
Closures will be in place from 9pm on Friday 24 July until 5am Monday 27 July 2026.
Further closures will be held in August and September.
HS2 said: "Traffic management will be in place to enable our workforce to safely continue installing beams for the M42 Motorway Box in Solihull and to progress deck installation works on the Water Orton Viaducts across the motorway in North Warwickshire."
