Major £750,000 Improvement Project for A90 Cowie Bridge near Stonehaven

Project starts Saturday 10 August and is expected to take up to nine weeks


A major road maintenance project for a bridge on the A90 near Stonehaven has been announced which will see over £750,000 in improvements carried out.

Work on the A90 at Cowie Bridge in Stonehaven is set to begin on Saturday 10 August for approximately nine weeks. The A90 is used by around 28,000 road users each day and the investment will help ensure the route continues to function safely for years to come.

Following on from improvements completed earlier this year, the project will involve re-waterproofing of the whole bridge deck, carrying out concrete repairs, kerb upgrades, replacement of bridge expansion joints, upgrade the central reserve safety barrier as well as resurfacing of both carriageways on the bridge deck. 

Major improvements had been scheduled to take place last year but due to the final stages of the construction of the AWPR, the work was postponed to a later date to minimise any inconvenience to road users.   

The A90 Cowie Bridge deck and southbound carriageway has been prone to potholes and other road defects in recent years, with some deterioration accelerating during adverse weather conditions.  Although temporary repairs have been carried out to address the carriageway surface, the investment from Transport Scotland will allow teams to complete a full surfacing repair which will ensure the bridge continues to operate safely for years to come.

To keep roadworkers as well as motorists safe during the upgrades and to complete the work in the shortest possible timescale, a contraflow system will be in operation for the Cowie Bridge deck repairs.  This traffic management will be in place from Saturday 10 August and will remain in use 24/7 throughout the project. The project will start on the northbound carriageway first meaning two-way, single-lane traffic will be in operation on the southbound carriageway.  Work will then switch around mid-September to the opposite side with traffic diverted via the northbound carriageway for the remainder of the project.   

Road users are warned to expect delays while the work is underway and are encouraged to plan ahead. Traffic modelling software has indicated that the project will increase the average journey time through the works by around 20 minutes at peak times during the day. However, these times may be extended depending on traffic flows in the area.

Consultation is underway with Aberdeenshire Council, Aberdeen City Council, Community Councils and transport operators to inform them of the plans for the project in advance.

Commenting on the project, Andy Thompson, BEAR Scotland’s North East Representative said: “This project of road improvements, worth over £750,000, will allow our teams to carry out full repairs to the bridge deck on the A90 at Cowie, creating a safer journey for motorists. 

“The road surface has been particularly damaged following the adverse weather conditions at the start of the year, and although teams have completed temporary repairs, this project will allow us to permanently repair the road.

“We’ve planned these works to be carried out under a contraflow system to keep everyone safe during the project. Our teams will do all they can to carry out the work as quickly and safely as possible.

“We’re liaising with all relevant stakeholders to keep them fully informed of the project and will take all feedback on board.

“We thank motorists for their patience in advance while our teams carry out these essential works on Cowie Bridge. We encourage road users to plan their journeys in advance by checking the Traffic Scotland website for up to date journey information and leave some extra time for their journey.”
