WORK will begin next month on rebuilding two separate sections of the A189 Spine Road in south east Northumberland.
The £550,000 revamp will start on Monday, July 18, on two sections of the northbound carriageway of the Linton Colliery-Newcastle road.
It is expected to take eight weeks to complete.
The improvements will be carried out at Shankhouse at Cramlington and Bebside, near Blyth.
A bridge parapet at the Three Horse Shoes Roundabout at Horton will also be replaced.
To minimise inconvenience to road users, Northumberland County Council intends to carry out the works during the school summer holidays, and complete the work in phases over longer working days.
During the works, through traffic will be maintained using a contraflow traffic management system.
Diversions will be in operation for northbound traffic that would normally use the A189 at the B1505 Shankhouse slip roads and the A192 Three Horse Shoes Roundabout slip road.
Two weekend night-time closures of the A189 northbound and southbound carriageways at the Three Horse Shoes Roundabout will also be needed to carry out works on the bridge.
Traffic will use the slip roads in either direction, as well as the roundabout, as diversion routes.
Coun Alan Thompson, the council’s executive member for highways and transportation said: “This £550,000 scheme is part of an ongoing programme of maintenance works in the county.
“The A189 is one of the busiest roads in Northumberland, with more than 40,000 vehicles using it every day.
“It is fundamental to the economic, social and environmental wellbeing of the area, so it is vital that the road is maintained and remains in a good condition.”
“While motorists can expect delays, every consideration has been taken to minimise inconvenience during this essential upgrade. I hope that they will appreciate the end result, and we do endeavour to complete the works as soon as possible.”
