A9 Dalraddy to Slochd


This 25 km road from Dalraddy to Slochd is being upgraded to dual carriageway as part of a wider programme to improve the A9 between Perth and Inverness. Design work is being taken forward by our consultants Atkins Mouchel Joint Venture.

Community engagement

Engagement with directly affected communities and businesses is at the heart of Transport Scotland’s projects and is a vital part of our work as we develop our ambitious plans to dual the A9 between Perth and Inverness. These engagement events regularly take place along the route.

Public Exhibitions

Public exhibitions are being held to let the public see, and comment on, proposed junction layouts for the Dalraddy to Slochd dualling project.

Public drop-in - November / December 2017

Public drop-in events are taking place in Aviemore on 30 November 2017, and Carrbridge on 1 December 2017. The sessions will give visitors an opportunity to see the development of the design following identification of the preferred route earlier this year. This will include details on access and side road arrangements, Non-Motorised User (NMU) provision, drainage design and the location of lay-bys.

Preferred Option - March 2017

Public exhibitions were held in Aviemore on Thursday 2 March and Carrbridge on Friday 3 March 2017 to let locals and road users see and comment on the preferred option for the Dalraddy to Slochd project.

Designing the route

The project has a number of considerations in the ongoing design process:

  • the northern extent of the section beyond Black Mount Junction is severely constrained by the hard geology, the railway and the need to widen the 3-span 145m Slochd Beag Underbridge
  • the River Dulnain Underbridge (3 spans and 80m across) will require widening
  • there is peat present in the area
  • this section contains 21 Non-Motorised User (NMU) crossing points
  • the southern part of this section is important from an environmental perspective. It contains multiple SAC (Special Area of Conservation), SPA (Special Protection Area), SSSI (Site of Special Scientific Interest) sites, a nature reserve and ancient woodland.
