Network Rail is investing £16m to replace the uniquely designed bridge that takes the Greek Street roundabout, Stockport, 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.
Work to the major junction in the centre of Stockport will begin next year, with some preparation work required this Christmas.
From spring 2025, the Greek Street roundabout will be closed to traffic for approximately one year. Diversion routes for pedestrians, cyclists, buses, and motorists are being carefully planned and will be clearly signposted.
Rail closures are required during Easter, summer and autumn 2025 to allow engineers to safely carry out the work.
Passengers will be advised on what this means for them with plenty of time to plan their journeys in advance.
Demolishing and rebuilding the 58-metre-wide bridge will be a complex process. Engineers will construct a temporary bridge to reroute existing utility services such as water and electricity. Then, the road layout will be removed carefully in a way that does not damage the bridge structure while the railway is in operation.
Over 20 days in 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.
Network Rail is working with Stockport Council, Transport for Greater Manchester, Avanti West Coast and other industry partners to make sure residents, local businesses and visitors to the area know how they will be affected by the work.
Cllr Grace Baynham, cabinet member for Parks, Highways and Transport services, said:“Greek Street is a major route in and out of our town centre and it is essential that these works to replace the bridge below the roundabout are carried out as soon as possible, especially as we look for the bridge to be designed for our future plans to bring the Metrolink to Stockport.
“The project team will continue to be in close dialogue with residents and businesses locally while the works take place as it is essential that we minimise disruption for both road users and train passengers throughout the project .”
