Ageing M42 Junction 6 bridge to be demolished and rebuilt to keep drivers safe

National Highways shut the bridge on the north section of the junction’s roundabout in July because of damage to the concrete and some corrosion of the steel reinforcement of the structure.

Detailed assessments have found that the bridge, which was built 50 years ago, is at risk of further deterioration and strengthening would not provide a long-term solution.

National Highways is aiming to minimise disruption by demolishing the bridge at the same time as one of the planned closures of the M42 between Junctions 6 and 9 for HS2 works in the coming weeks.

National Highways Head of Network Planning and Development, Ian Doust, said:

“Many of the motorways and structures we manage were built over half a century ago and now need renewing or replacing to ensure they remain fit for purpose

“Safety has to be our priority which is why we closed the bridge when we saw such a rapid change in the condition of the structure.

“Investigations showed that the most effective and efficient solution is to demolish the bridge and re-build it to modern standards to keep people and goods moving safely and reliably.”

Inspectors assess some of the defects under the bridge

A 7.5 tonne weight restriction was initially imposed to safeguard the bridge when the structural defect was discovered. But the bridge had to be closed in July after further deterioration was identified.

Plans are now being developed for a temporary bridge to be introduced at the junction until a replacement structure can be installed.

Further updates about the demolition and next steps will be provided as soon as possible.

National Highways will continue to engage with stakeholders including Birmingham Airport and the NEC to provide the very latest information so they and their customers can plan their journeys.

Current diversions around the bridge closure will remain in place until further notice. More information on these can be found online.
