National Highways has started work on an important safety upgrade of the central barrier at the busy M40/M42 interchange near Birmingham.

The work involves upgrading 7.5 miles of steel safety barrier to a concrete one between the M42 junction 3 and junction 3a, and M42 junction 3a to M40 junction 16.

Concrete safety barriers are also virtually maintenance free and will last twice as long as normal metal barriers, with far less need for closures for routine repairs.

National Highways Regional Sponsor, Paul Unwin, said: “Concrete barriers improve safety by reducing the risk of vehicles crossing over into the other carriageway, which can also cause lengthy traffic delays. This is an important safety upgrade and is a huge benefit to road users.”

During the works, three slightly narrower lanes will remain open to traffic and also creating a safe space for working around the central reservation. There will be a reduced speed limit of 50mph, CCTV coverage and a free recovery service.

Night closures will take place while traffic management is installed with the three narrow lanes up and running and the barrier replacement getting under way early March. Work is due to be completed next spring.
