Preparations are well under way for a major upgrade to the West Coast Main Line crossing over the M6 at Clifton, near Penrith.
Network Rail is investing £60 million to replace the 60‑year‑old structure, ensuring it can continue to carry both passenger and freight trains safely over one of Britain’s busiest motorways.
Why the Upgrade is Needed
The current bridge’s age and condition mean it can handle only one train at a time, leading to delays. The new design will eliminate these restrictions, boosting efficiency and reliability for travellers and freight operators alike.
What’s Coming Next Year
Due for completion in January next year, the new bridge will:
- Stretch 130 metres in length
- Weigh around 3,000 tonnes
- Feature a modern three‑span structure supported by Very Important Beams (VIBs)
Progress on Site
In recent weeks, Network Rail and contractor Skanska have welcomed delivery of the first of five enormous VIBs. These components are being manufactured in Glasgow, then transported south to a purpose‑built work site beside the M6 for assembly.
With each delivery, the transformation of this key railway link comes closer to reality — promising smoother journeys across the heart of the UK rail network.
William Brandon, Network Rail’s project manager, said: “We are rebuilding Clifton bridge over the M6 to keep rail passengers and motorway users safe for years to come. This project is essential as the bridge has reached the end of its life.
“It’s fantastic to see the first parts of the bridge arrive on site six months before the work.
“The main work, which involves rail and road closures, is not happening until January 2026. However, people living in the Clifton area or driving past might notice the start of our construction activities.
“We’re working with National Highways to make sure we can carry out our work as safely as possible with as little inconvenience to local people and the travelling public. Thank you for your patience during this critical work.”
Rosario Barcena, Skanska’s rail programme director, said: “We’ve had fantastic collaboration on this project, including with Network Rail, National Highways, local authorities and our supply chain partners.
“To see the first steels arriving on site is a massive achievement. Our expert team is now very much focused on building the new bridge off site and planning for its installation in early January.
“As part of our works, we’ve had the opportunity to showcase careers in rail, engineering and construction and we’re delighted to have recruited two local apprentices.”
