The £2.85m project will “secure the future of journeys for rail passengers between Manchester and Liverpool”, according to the arm’s length public body.
South Lane railway bridge near Warrington will be rebuilt between the Widnes and the Sankey for Penketh stations.
The work is part of Network Rail’s Great North Rail Project, a multi-billion pound programme of improvements to the region’s railway infrastructure. Other projects include upgrading the Transpennine Route and extending platforms in the North.
Rebuilding railway bridges will help keep the railway safe and reliable, according to Network Rail.
“The work on South Lane railway bridge as part of the Great North Rail Project will secure the future of the railway through Warrington for decades to come,” said William Brandon, scheme project manager for Network Rail.
Work on South Lane railway bridge will take place over 13 weeks starting on 2 August. During that time, the road beneath the bridge will be closed. It will reopen at the end of October. In the meantime, drivers and cyclists will be diverted via Widnes Road (A562) and Watkinson Way (A557).
The railway line itself will be closed on 11 and 12 September to allow for work to be done.
Two other rail bridges near Warrington are also being rebuilt by Network Rail this summer: Bewsey Street and Foundry Street. Those schemes are also part of the Great North Rail Project. Work is expected to begin on those bridges this month.
