The bridge that carries the A1 trunk road over the East Coast main line railway at Allerdene, close to junction 67 near Gateshead and the Angel of the North, is to be partially closed to road traffic while its expansion joints are replaced as they are approaching the end of their useable life.
Due to the layout of the road over the bridge, and the nature of the work required, it can only be carried out safely if one of the carriageways is closed and the work is carried out overnight.
Weekday overnight closures of the A1 southbound between junction 67 (Coal House) to junction 66 (Eighton Lodge) will be required from Monday 2 November to Friday 6 November and Monday 9 November to Friday 13 November.
Northbound, the A1 will be closed between junction 66 (Eighton Lodge) to junction 67 (Coal House) from Monday 16 November to Friday 20 November and Monday 23 November to Thursday 26 November.
Weekend closures may also be needed in between the dates highlighted above, which are all weather dependent.
Train services should not be affected by the work being carried out on the bridge.
Amjad Khan, project manager for Highways England, said: “We understand overnight closures will cause disruption, and I’d like to thank people for their patience in advance. While the bridge is safe, it’s extremely important we take measures to maintain it so it stays that way.”
“The work is being carried out in two phases, with each phase needing several overnight closures of the A1 in one direction at a time, so our team of engineers can work around the clock to complete the job as quickly as possible.”
Diversions will be clearly signposted during the closures.
