Work is due to start next month to rebuild a number of bridges in Lancashire. It will be part of a £400m electrification programme to provide a better railway across the north of England.
Bridges at Harpers Lane in Chorley, Railway Road in Adlington, and Lostock Lane in Bolton will be rebuilt to allow overhead electricity lines to run underneath to power trains from December 2016.
This work is billed to improve rail connections between Manchester and Preston via Bolton, delivering a more reliable, efficient and greener railway.
Ian Joslyn, area director for Network Rail, said: “Our programme of work to electrify the railway in the North West and upgrade the infrastructure as part of the Northern Hub will provide many benefits to passengers, including faster journeys where possible and more seats and capacity.
“To deliver improvements on this scale, we have to rebuild several bridges to accommodate the new infrastructure, which means causing short-term disruption in certain areas.
“We have done all we can to plan the work to complete it safely in the shortest amount of time to help keep disruption to a minimum. I apologise for any inconvenience caused and thank local people for their patience while we complete these essential upgrades.”
The North West Electrification Programme is being delivered in five phases until December 2018, and will electrify 352km of track across the North West of England.
