A 3D, computer generated video explains how engineers will demolish and rebuild the Greek Street roundabout in Stockport, which crosses Europe’s busiest mix-used railway.
The video has been revealed by Network Rail ahead of the closure of the roundabout this month.
The bridge takes vehicles and pedestrians in Stockport over the West Coast Main Line, which sees almost 400 services pass through Stockport station every day.
The Greek Street roundabout will be closed to traffic for one year starting from 31 March 2025.
This closure is part of Network Rail’s almost £20 million investment to replace the aging bridge that crosses over the West Coast Main Line.
The original bridge, which was constructed in 1958, has reached the end of its life and needs to be replaced.
A video has been published that shows exactly how engineers will replace the 67-year-old structure.
Olivia Boland, Network Rail sponsor, said: “We’re replacing the Greek Street bridge in Stockport to keep the railway below and road users above safe for years to come.
“This video is a fantastic way to explain how complex the work to replace the bridge is. It brings to life this the true scale of the work required.
“We are very grateful for the cooperation of the local community during the work. I know that closing the roundabout for a year will disrupt the daily lives of the local community, and I am very sorry for the inconvenience this will cause.”
Residents are being reminded that, from 31 March, the Greek Street roundabout will be closed to traffic for one year.
Road users and pedestrians are being informed of diversionary routes during the closure. Network Rail has worked carefully with Stockport Council and Transport for Greater Manchester (TfGM) to establish safe and convenient diversionary routes during the major closure.
Over Easter 2025, work will take place to prepare the railway for the bridge’s replacement this summer. There will be changes to train services between 19-22 April 2025. Passengers are advised to check National Rail Enquiries before they travel. Some services will be diverted around Stockport, whilst others will be replaced with a bus.
Demolishing and rebuilding the 58-metre-wide bridge will be a complex process. Over Christmas 2024, engineers constructed a temporary bridge to reroute existing utility services such as water and electricity. Once the road is closed, the road layout will be removed carefully in a way that does not damage the bridge structure while the railway is in operation.
Between 2-23 August 2025, the bridge, which is made of about 200 concrete beams, will be demolished and the new bridge will be installed. Then, the team will redirect the utility services, waterproof the bridge, and reinstate the road to the highest standard.
The video was produced by Bionic Group with detailed instructions and guidance from the project’s principal contractor, Murphy.
