Stockport Metropolitan Council has said that challenging ground conditions and risk of ground collapse will delay opening of the A6 to Manchester Airport Relief Road (A6MARR) by up to five months.
The road was being built by a joint venture of Morgan Sindall and Carillion but the council has said it is the earthworks that have delayed the scheme, rather than the collapse of Carillion.
Morgan Sindall has taken over delivery of the scheme following Carillion’s liquidation but the opening date of the road has been put back from spring this year to late summer.
In a statement, the council said: “Since work began in 2015, contractors have faced sustained periods of bad weather. This has continued this winter with further heavy rain, meaning that plans to make up for previous delays have not been possible.
“Throughout construction detailed ground investigation surveys have been undertaken to inform the work taking place. As these have been completed, it has been found that the ground conditions are more challenging than investigative works anticipated. This combined with heavy rainfall has affected the speed of progress possible with the earthworks and construction.
“At the same time, Stockport Council has recently become aware of significant problems with the highway drain under the A555 which needs urgent and essential repairs to stop a potential road collapse and ensure the safety of motorists. This emergency repair work requires the full closure of the A555 westbound from the A34 to Wilmslow Road and was not part of the original work planned on the relief road but needs addressing urgently.”
Stockport cabinet member for economy and regeneration added: The A6MARR project has faced a number of challenges and while a lot of work has taken place to reduce their impact they have affected progress on the project, and unfortunately we will be unable to open the road as planned this spring. On behalf of the whole project team, I apologise for this further delay and want to assure residents and businesses that we are continuing to work very closely with the contractor to get work completed and the road open as soon as possible.”
