Updated notice of overnight closures of the M42 motorway between junctions 9 and 10

What we are doing

We are progressing works on the Marston Box bridge that has been installed across the M42 Motorway between junction 9 and 10. Over the next few months we will complete works to install the parapets on the bridge. These features on a bridge are vitally important as parapets provide safety to passing vehicles below and can also act as a noise barrier.
Before we install the parapets, we will require temporary overnight carriageway closures to undertake:

• Drainage surveys
• Structural survey of Marston Box
• Installation of monitoring equipment and signage

We are working closely with National Highways to complete these works safely and efficiently. There will be temporary overnight carriageway closures of both the M42 southbound and northbound:

• Northbound carriageway closure (Junction 9 to 10) – Overnight on 6 June and 7 June 2023. The closures will be from 9pm to 5am
• On 7 June 2023 there will also be a single lane closure on the southbound carriageway overnight from 9pm to 5am
• Southbound carriageway closure (Junction 10 to 9) – Overnight on 8 June and 9 June 2023. The closures will be from 9pm to 5am

A clearly signed diversion route will be in place over this period with advance signage in place to help inform motorists of the closure.

Please note: There is a low bridge at Piccadilly (Kingsbury) that is unsuitable for HGVS, please follow the signed diversion route.
