To help protect the structure and keep the junction open for the vast majority of traffic, a weight restriction for vehicles over 44 tonnes is already in place.
From 11 May 2026 we’ll also introduce a lane one closure on the roundabout.
Our detailed inspections and daily monitoring will continue so we can:
- understand the full extent of the deterioration
- determine the most appropriate remediation options.
We’ll provide further updates as this work progresses.
What this means for your journey
• two lanes will remain open for traffic on the roundabout
• vehicles over 44 tonnes should follow signed alternative routes
• drivers may experience some congestion at peak times
• the M42 remains open in both directions beneath the bridge
