A 50-year-old concrete bridge that had to be closed to traffic will be demolished and rebuilt after it was found to be at risk of further deterioration.

The structure, over the M42 near junction six for Birmingham Airport, was shut in July when inspectors discovered damage to the concrete and corrosion in some of the steel reinforcement.

National Highways said detailed assessments found strengthening the bridge would not provide a long-term solution.

Ian Doust from National Highways said: "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."

He added: "Investigations showed that the most effective and efficient solution is to demolish the bridge and rebuild it to modern standards to keep people and goods moving safely and reliably."

"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."

The bridge will be demolished during one of the planned M42 closures between junctions six and nine for HS2 works in the coming weeks.

Current diversions around the bridge closure will remain in place

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.

Current diversions around the bridge closure will remain in place until further notice.
