  Lighting issues to be corrected

  While our safety barrier upgrade of the M40-M42 interchange was completed before Christmas - several months earlier than planned - we identified some longstanding issues with lighting that were not part of the original project scope.

  We're correcting these issues now while we're still in the area and to do this safely, we need to install the following closures which will take place at night when the level of traffic is expected to be lower.

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

  Date	Details	Closure & Diversion Route
  11 - 13 September 2024	M40 northbound junction 16 to M42 northbound junction 4	Lane closures leading to full closure of M40 northbound to M42 northbound link road Diversion via M42 junction 3 and return
  11 -13 and 18 September 2024	M42 southbound between junctions 4 and 3a	Lane closures
  16 – 17 September 2024	M40 northbound between junction 16 to M42 junction 3a southbound	Lane closures leading to full closure of M40 northbound to M42 southbound link road   Diversion via M42 junction 4 and return
  	M42 northbound between junctions 3 and 3a	Lane closures
  18 September 2024	M42 southbound to M40 southbound link road	Full closure of M42 southbound to M40 southbound link road Diversion via J3 and return
  	M40 J16 northbound entry slip road	Full closure of M40 J16 northbound entry slip road Diversion via local authority network to M42 J4 and return

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

  As there are other highway schemes in the local area, it is advisable that you also check the web pages relating to your travel.

  Lighting work in July

  While upgrading central reservation barriers, we identified some issues with lighting .

  We'll be correcting lighting along this stretch of the motorway while we're still in the area.

  We'll need overnight closures from 9pm to 6am while we work at these locations:

  • M42 southbound between junctions 4 and 3
  • M40 northbound between junctions 16 and 3a

  Please remember that closure details can change at short notice.  For the most up-to-date information, please visit our daily closures page.

  Our programme of work

  Our safety enhancement work to upgrade the central reservation barrier along the M40 and M42 near Birmingham is now complete. However, we will continue to deliver essential maintenance work, including new road markings and drainage repairs, along this section of the network through February 2024.

  Since February 2023, we have replaced more than five miles of steel barrier with a safer, more efficient concrete barrier.

  Concrete barriers are much stronger than metal ones and significantly reduce the risk of vehicles crossing over from one carriageway to another, improving safety and reducing the duration of incident-related congestion. They greatly reduce the need for maintenance and will last twice as long as normal metal barriers, with far less need for closures for routine repairs.

  The early finish is down to a number of factors, including the use of an innovative new precast concrete barrier which can be laid faster than other types of concrete barrier. It has a different foundation design that allows a quicker installation process and eliminates some of the time-consuming post-installation operations required for other barriers.

  Staff working on the project are now carrying out similar safety upgrades on the M42 between junctions 4 and 7. 

  We would like to thank the local community and motorists for their continued patience while this important work is carried out.
