A90 Aberdeen Western Peripheral

Scheme outline

Construction of a new dual two-lane grade separated bypass to carry the A90 around the western side of Aberdeen. This scheme constitutes the longest length of road under construction in the UK.

Its progression through the statutory planning process was particularly difficult and subject to a number of revisions to the road scheme and legal challenges from activists and others who were opposed to the road being built.

The northern section went to an extra consultation stage, and was eventually confirmed as taking a slightly circuitous route around the north of Aberdeen to rejoin the existing A90.

At the southern end, a section called the "fast link" will connect to the Stonehaven Bypass. This part has been particularly criticised for connecting to the existing A90 at Stonehaven with a low-standard junction, and for connecting to the rest of the Western Peripheral at a flat roundabout junction.

This scheme was completed in and we're no longer accepting updates or changes to this page.

The appeal may still be dropped if the anti-road campaigners are unable to secure an agreement to have their legal expenses capped.

29 May 2018

Cones and "road ahead closed" signs spotted on the AWPR between Blackdog (current A90) and Goval (A947) suggest parts of the new carriageway may open to traffic in advance of the opening of the full length of the scheme, which is expected in the autumn.

27 June 2018

The road between Goval and Blackdog is fully opened with national speed limit in place

There had been some confusion, as previously Transport Scotland had stated Autumn 2018 for opening.

The latest statement about the road’s opening from the Scottish Government is "no definitive date". Concerns have been raised over defects to the River Don crossing section even before opening.

8 November 2018

According to local media, the AWPR contractors now state the problematic River Don Crossing will be "ready in December". Local politicians are calling for other sections which appear to be complete be open sooner. Apparently the contract prohibits this which has lead to the Scottish government promising a review of future contracts.

BBC News reports that completed sections will open next week. The Don Crossing still remains closed due to remedial works.

11 December 2018
The 19.5 mile section between Stonehaven and Dyce is due to be opened 12 December after an agreement was reached between the contractor, their lenders and Transport Scotland which allowed a variation to the contract.
12 December 2018

Most of the road opened early this morning, with only the problematic River Don crossing remaining closed to traffic.

20 December 2018

Transport Scotland have confirmed the Aberdeen bypass will not be fully open in time for Christmas. The final 4.5 mile stretch, between Parkhill and Craibstone, had planned to open before December 25.

Instead the firm are targeting a January 2019 completion, although no definitive date has been confirmed.

18 January 2019

All contractor's equipment has now been removed from the problematic Don Crossing and it looks to be ready for traffic . However temporary diversions and plenty of traffic cones still in situ either end. No official word on full opening of this last remaining section of the AWPR.

The AWPR is now fully open. The final section between Craibstone and Parkhill was opened to traffic this morning, according to Transport Scotland.
