M42 junction 4-7 safety barrier upgrade

Latest updates

• 03 October 2024

  Improvements complete

  Our work to upgrade the M42 between junctions 4 and 7 is now complete.

  We’ve replaced the existing steel central reservation barrier with a safer and more durable concrete one between junctions 4 and 5. We’ve also installed additional CCTV cameras and signage between junctions 4 and 6.

  We minimised disruption as far as possible without compromising the safety of road users and the workforce but recognise some disruption was unavoidable. Thank you for your patience while we made these improvements.

  You may see some of our crews on the network overnight for a short period while we rectify some longstanding drainage issues that were not part of the original project scope.

  Work continues during September

  We’re delivering safety upgrades to the central reserve barriers on the M42. Our work includes replacing the existing steel barrier with a stronger and more efficient concrete one, as well as installing new CCTV and roadside signage. We're on schedule to complete the scheme this autumn.

  Work began in early 2024 with some closures in place to allow for the installation of traffic management, to ensure the safety of all road users and our team while construction is underway. To offer additional safety and assurance, those lanes are covered by CCTV and operate at 50mph. There's also a free recovery service in place for vehicles that break down within our roadworks.

  To continue our work, we require further closures, as shown below.

  Upcoming night time (between 9pm and 6am) closures

  Date	Details	Closure & Diversion Route
  16 – 17 & 25 – 26 September 2024	M42 southbound junction 6 – 5	Lane closures

  Please note: these closures may be amended due to poor weather or for operational reasons.

  There are other schemes underway in the local area, so please check the webpages relating to your travel, allow extra time for your journey travel and of course, pay attention to signage on the highway.
