Boulderstones bridge, which takes the A530 Middlewich Road over the railway between Crewe and Chester, has been renewed by Network Rail in a £5.7 million project and the line reopened to passengers.
Middlewich Road will remain closed until October whilst the finishing touches to the bridge are completed.
The original bridge was removed in June and the modern structure that has replaced it will need of less maintenance in future.
Network Rail scheme project manager Oluwole Osunneye said: “This essential Railway Upgrade Plan work will bring the crossing over the railway up to modern standards, making it safe and reliable for both traffic above and rail passengers below.
“We are very grateful for the patience of rail passengers and road users in Crewe while we completely renew this bridge – reducing traffic and train delays in the years to come”
This major bridge replacement follows the successful £11 million refurbishment scheme of another railway bridge in Crewe, at Sydney Road, in September last year.
