The steel framework of the new Clifton Bridge, which will carry West Coast Main Line trains over the M6 near Penrith, has been completed, with installation planned for a two‑week window in January 2026.

New aerial shots highlight the scale of the structure — around 130 metres long and weighing approximately 4,200 tonnes — which Skanska's rail team will install at the start of the year. The bridge replaces a nearly 60‑year‑old concrete span currently restricted to one train at a time, a limitation that has contributed to service delays.

To maximise the planned dual closure of the West Coast Main Line and the M6, Network Rail will renew more than 80 kilometres of overhead power cables and advance a £61 million digital signalling upgrade north of Carlisle.

William Brandon, Network Rail's project manager, said: "This ambitious project will provide a vital upgrade to the West Coast Main Line and improve reliability and journey times for passengers.

"While we close the railway to replace the M6 bridge we'll also be renewing more than 80 kilometres of overhead lines and continuing our major modernisation of signalling systems. We appreciate passengers' patience while this work is completed, and I would urge anyone planning to travel in this period to check National Rail Enquiries in advance."

Rosario Barcena, Skanska's rail programme director added: "We have made fantastic progress. The bridge has been built on schedule and our preparatory work for the removal of the current structure and installation of the new one is nearing completion. These planning works include a trial move of the new bridge using self-propelled modular transporters (SPMTs) before Christmas.

"This progress has come as a result of close working between all the partners involved including Network Rail, National Highways, our supply chain team and local community."

Over the Christmas period, Network Rail teams will carry out a broader programme of improvements on the West Coast Main Line, part of an ongoing £196 million investment across the route's northern and southern sections.
