The new aerial images show the scale of the new bridge close to Penrith, measuring 130m in length and weighing around 4,200 tonnes, which will be installed by our rail team during a two-week period at the beginning of 2026.
It replaces a previous concrete structure which is nearly 60 years old and has weight restrictions that mean only one train at a time can cross it, causing delays to services.
To make the most of the dual West Coast Main Line and M6 closure, Network Rail will also install more than 80 kilometres of overhead cables which power trains and significant work will take place on an ongoing £61m digital upgrade to signalling systems 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 be undertaking a major programme of upgrades to improve journeys for passengers on the West Coast Main Line. These are all part of an ongoing investment of £196m by Network Rail into both the northern and southern sections of one of Britain’s busiest rail routes.
Anyone travelling on the West Coast Main Line during this period should check www.nationalrail.co.uk for the latest travel information.
