M6 Thelwall Viaduct
Part of our ongoing programme of work to maintain England's strategic road network
Where was the project located?
Thelwall Viaduct is located between junction 20 and 21 of the M6, carrying this important route over the River Mersey and Manchester Ship Canal.
Why was the scheme needed?
The scheme was needed as the bridge joints had started to fail and we have already had to undertake a couple of urgent repairs, causing delays to drivers.
What work was carried out?
We replaced the bridge expansion joints. This was a large but routine maintenance project as the joints cross the carriageway and allow the bridge to move safely during changes in the weather and different traffic conditions. Resurfacing works were also carried out.
How did this benefit road users?
The new bridge joints will extend the life of the bridge, ensuring this vital road link is kept in good working order. Replacing the joints all in one go caused less disruption than a series of works. The new joints will reduce the need for future maintenance and emergency work, providing a more reliable journey.
How do I find out more information ?
If you have any queries about this project you should contact the Highways Agency Information Line by emailing email@example.com or calling 0300 123 5000.
Will there be roadworks?
Yes, roadworks will be required to allow us to safely replace these bridge joints. This section of motorway is one of the busiest in the country, with around 160,000 drivers using Thelwall Viaduct every day. We are doing all we can to minimise disruption - please help us by:
- avoiding the viaduct where possible, especially at peak times
- driving safely through the road works - there will be heavy plant machinery moving around and narrow lanes as well as oncoming traffic within the contraflow
- planning your journey - check traffic conditions before setting out and allow extra time.
How will you manage traffic?
Further works on the final joint will be carried out over the next few weeks under lane closures. This will also affect the M6 junction exit slip northbound and will require closures.
Will there be diversions?
During the closures fully signed diversion routes will be in place.
