A9 Dalraddy to Slochd

A9 Dalraddy to Slochd is one of the 11 schemes that form the Scottish Government’s £3 billion A9 Dualling between Perth and Inverness. The 24.1km scheme is being designed by Atkins/Mouchel Joint Venture on behalf of Transport Scotland with the intention of developing route options and progressing the scheme through the statutory process. 

In Preparation

More details of this process can be found on:

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 and details can be found on the Community engagement web page.

Update on Junction Arrangements - June 2016

The report on this exhibition has been published.

A further round of public exhibitions for the Dalraddy to Slochd project were scheduled for 16 and 17 June 2016, aiming to present further work that has been undertaken on the junction arrangements for DMRB Stage 2 Assessment both with respect to location and layouts.

The exhibitions also gave a further opportunity for the public to provide feedback on the recent work to help inform the on-going development and assessment of the dualling proposals between Dalraddy and Slochd, as we progress into the final stage of the assessment to identify a preferred option.

Exhibitions were held on:

  • Thursday 16 June 2016 – 12 noon - 8 pm – Aviemore Community Centre (The Studio), Muirton, Aviemore PH22 1SF

Design Challenges

Following the initial work undertaken by the Preliminary Engineering Services Commission a DMRB Stage 1 report was produced for the whole of the A9 corridor and for this particular section the following must be considered as part of the ongoing design process:

  • The northern extent of the section beyond Bogroy Junction is severely constrained by the hard geology, the railway and the need to widen the 3-span 145m Slochd Beag Underbridge.
  • The remainder of the section is not without construction challenges due to the need to widen the 80m 3 span River Dulnain Underbridge,
  • The presence of peat
  • This section also contains 21 Non-Motorised User (NMU) crossing points which is the highest in the A9 corridor.
  • The southern extent of the section is noted in the SEA (Strategic Environmental Assessment) Environmental Report as being one of the most constrained of the route from an environmental perspective due to the multiple SAC (Special Area of Conservation), SPA (Special Protection Area), SSSI (Site of Special Scientific Interest) sites, a Nature Reserve and Ancient Woodland.

Indicative Route Option Plan

As part of the May 2014 public exhibitions Transport Scotland have presented plans detailing indicative route options for this section of the A9 dualling.
