Engineers are to begin installing bridge beams on the A90 southbound carriageway.

A total of five 43-metre long beams, each weighing 68 tonnes, will be installed on the route as part of the Aberdeen Western Peripheral Route/Balmedie to Tipperty (AWPR/B-T) project.

Work will take place overnight on Saturday, 01 July and Sunday, 02 July. For safety reasons, the B979 between New Mains of Ury and Glenury Road will close from 8pm on Friday, 30 June and reopen around 6am on Monday, 03 July to enable the beams to be delivered and installed safely.

A further closure on the B979 will be required from 8pm on Monday, 03 July until around 6am on Tuesday, 04 July to enable the contractor to undertake further installation works, which will include the bases for parapets. There will be no access to the A90 via the new southbound slip road during these closures. Diversions will be in place.

A Transport Scotland spokesperson said: "These vital bridge reconstruction works at Stonehaven are taking place over a weekend and at night when roads are quieter to minimise inconvenience to road users. It should be noted, however, the Stonehaven half marathon will also be taking place on Sunday 2 July. Although the route is not affected by the AWPR/B-T project works, anyone participating in this event, providing support to the runners or spectating should plan their journey in advance to ensure they can get there safely and on time.

"Once the beams are in place, the contractor will continue to reconstruct the A90 southbound carriageway. After these works are complete, the contraflow currently on the northbound carriageway will move to the new southbound carriageway to allow the remainder of the existing bridge to be demolished and reconstructed.

"The works at Stonehaven involves widening the B979 Netherley Road and the creation of a new roundabout, which will form the junction between the AWPR, the A90 and the B979. A new slip road on to the A90 from the B979 has already opened."
