Work is to begin to deliver bridge beams on the £745 million Aberdeen Western Peripheral Route/Balmedie to Tipperty (AWPR/B-T) project.

A total of 12 beams and 44 bridge parapet units are being delivered in order to build two new bridge on the A90 near Blackdog.

Six of the beams are 46 metres in length for the new southern bridge at Blackdog Junction, while the other six beams are to be installed as part of the new northern bridge. The beams will be welded and assembled in pairs before they are delivered to Blackdog.

It is expected the beams will be delivered and installed over three weekends: Friday, 28 April to Monday, 01 May; Friday, 05 May to Monday 08 May and Friday, 12 May to Monday, 15 May.


A fourth weekend from 02 June to 05 June is required to complete the installation of the edge parapet units, after deck works on the two bridges have been carried out.

Additional traffic management measures, including A90 road closures with diversions and contraflows, will be in place to enhance the safety of road workers and road users.

A Transport Scotland spokesperson said: "The contractor has been working closely with Police Scotland and the local authorities to ensure that anyone who needs to use the roads at Blackdog over the next few weekends can do so, while maintaining the safety of road users and road workers.

"These works have been timed to take place over a series of weekends to help minimise the impact they may have on road users. However, road users who need to travel through or nearby this area during these weekends should plan their journeys in advance so that they can reach their destination safely and on time. For instance, they should consider using an alternative route, if possible, and giving themselves additional travelling time.

"We would like to thank road users and the local community for their on-going support and patience during the construction works."
