A9 Pass of Birnam to Tay Crossing

The 8.4km section of the A9 from Pass of Birnam to Tay Crossing is being upgraded to dual carriageway as part of a wider programme to improve the A9 between Perth and Inverness.

The Design Manual for Roads and Bridges (DMRB) Stage 3 assessment for the proposed scheme is now complete. The DMRB Stage 3 Scheme Assessment Report was published on 30 May 2025 alongside the draft Orders and Environmental Impact Assessment Report (EIAR) for the proposed scheme.

The draft Trunk Road Order defines the line of the proposed route for the proposed A9 trunk road. The draft Side Roads Order defines the new side roads, the improvement and stopping up of sections of existing road and the stopping up and provision of new private means of access, all in connection with the dualling of the A9 trunk road. The draft Compulsory Purchase Order defines the extent of the land required to deliver the project.

A copy of the draft Orders and the EIAR may be inspected, free of charge, during normal opening hours from 30 May 2025 to 25 July 2025 at the following locations:

• Birnam Arts, Station Road, Birnam, Dunkeld, PH8 0DS
• Transport Scotland, 177 Bothwell Street, Glasgow, G2 7ER

*Please note that normal opening hours might vary during this period.

Public in-person exhibitions will be held on 11 and 12 June 2025 to present the published draft Orders and EIAR and to provide members of the public, road users and the local community with the opportunity to discuss the proposed scheme with members of the project team. These events are being held at Birnam Arts and Conference Centre, Station Road, Birnam, PH8 0DS at the following times:

• Wednesday 11 June 2025, 11am – 8pm
• Thursday 12 June 2025, 10am – 6pm

A virtual exhibition showing the material which will be on show at the above events is now live, and will remain so until 25 July 2025.

Scheme Development

Strategic Environmental Assessment

Between 2012 and 2014 Transport Scotland completed a Strategic Environmental Assessment (SEA) to inform, at a corridor level, where dualling should take place and some key environmental themes or principles we would follow. The SEA helped inform the division of the programme into a series of projects to help us manage planning issues at a local level.

After the SEA Transport Scotland moved to project level assessment work, set out in the Design Manual for Roads and Bridges (DMRB). This involves a more localised assessment of constraints and opportunities and the production of route options and assessment of their impacts.

DMRB Stage 2 Assessment and the A9 Co-Creative Process

Following initial identification of route options to be considered at DMRB Stage 2, in Autumn 2016 Transport Scotland, in partnership with the Birnam to Ballinluig A9 Community Group, undertook an A9 Co-Creative Process to bring skills, experience and local knowledge to reach a solution with the community. This commenced in January 2018 and concluded in July 2018 with the identification of the Community’s Preferred Route Option.

Following the conclusion of the A9 Co-Creative Process, scoping work identified a number of challenges and concerns regarding the Community’s Preferred Route Option. As a result of the challenges identified, many of which are difficult to mitigate, three additional route options, taking into account the objectives of the community and the A9 Dualling Programme, were developed and assessed alongside the Community’s Preferred Route Option within the DMRB Stage 2 Route Options Comparative Assessment.

The Preferred Route for the Pass of Birnam to Tay Crossing section of the A9 Dualling Programme was identified and announced on 20 December 2023, with the DMRB Stage 2 Assessment Report published online.

DMRB Stage 3 Design Development and Assessment

The DMRB Stage 3 design development of the Preferred Route Option and subsequent engineering, environmental, economic and traffic assessment has now been completed. The DMRB Stage 3 Scheme Assessment Report has been published on 30 May 2025.

An extensive Environmental Impact Assessment (EIA) has also been undertaken alongside the DMRB Stage 3 scheme development and assessment, and this has also been published on 30 May 2025.

Community engagement is at the heart of the design and development of all of our major road projects. As part of that engagement, we regularly hold events to consult with local communities, road users, businesses and individuals as our plans are progressed.

A programme-wide A9 Dualling website featuring more information about the development and construction of the A9 Dualling programme has been launched.

In addition, a StoryMap webpage is regularly updated to provide information and news relating to the Pass of Birnam to Tay Crossing project specifically.

Public Exhibitions were also held in June 2013 and June 2014 at various locations along the route. Additionally, since 2013 a number of drop-in sessions were held to offer the community the opportunity to speak to the project team and to raise any points or queries they may have in relation to the Pass of Birnam to Tay Crossing scheme.

January/February 2012

We hosted an exhibition in January/February 2012 to give everybody the opportunity to see potential route options.

The exhibition boards are available in two parts:

• Public exhibition boards part 1
• Public exhibition boards part 2

See also the scheme leaflet.

In 2017, a partnership between Transport Scotland and the Birnam to Ballinluig A9 Community Group initiated a co-creative process to identify the community’s preferred route. The process was open to everyone, and the community group has been involved in each stage.

From January 2018, through a five stage co-creative process the community, including children and young people, suggested ideas for the A9 dualling and associated infrastructure, and the most popular of these ideas, as voted for by the community, were used to create a short-list of four ‘Whole Route Options’. In the final stage, Stage 5, members of the public were invited to rank the four short-listed routes in order of preference and to vote for one of three related junction options at Birnam/Murthly Castle. 

The four whole route options selected for the final voting were:

• three ‘online’ routes (Routes A, B and D) which would follow the line of the existing A9 (but partly at lower level involving a cut and cover tunnel or underpass) with junctions at Dunkeld, Dalguise and the Hermitage, and the retention of the Dunkeld & Birnam railway station
• one ‘offline’ route (Route C) which consisted of a 2.8km tunnel to the west of the existing A9 with junctions at Dalguise and the Hermitage, and the retention of the Dunkeld & Birnam station.

The online options had varying lengths of tunnel with Route A incorporating a 1.5km tunnel, Route B a 450m tunnel and Route D an underpass of up to 150m.

To complete the whole route, three options for junctions at the Birnam and Murthly Castle end of this section were also offered:

• a restricted movement grade-separated junction at Birnam
• a full movement grade-separated junction adjacent to the current access at Murthly Castle
• or a roundabout at Birnam.

Over the voting period, between 23 June and 2 July 2018, 720 people voted online or submitted voting cards. Voting was open to the public and the number of votes received represented a very strong turnout relative to the size of the community. The rankings were aggregated into total scores for each of the four short-listed routes to determine the preferred route.

Voting results

The online route (Route A) incorporating a 1.5km tunnel commencing in the area of the existing junction of the A9 with the B867 and Perth Road at Birnam and terminating in the area of the existing junction with the A923 and A822 at Little Dunkeld (See diagram, below) came out on top with the highest score, attracting 37.4% of the total of all scores across the four routes and also attracting 45% of the first place votes recorded.

Routes B, C and D attracted 23%, 22.3% and 17.3% of the total of all scores respectively. The full voting figures and scores can be found in the Stage 5 Ranking Summary Report, link included below.

To complete the whole route, voters expressed a clear preference to incorporate a full movement grade-separated junction at Murthly Castle, to the south of Birnam, to replace the existing Birnam junction. This option attracted 68% of the votes for junctions compatible with that route.

The community’s preferred route was announced on 13 August 2018. Subsequent scoping work was undertaken on the Community’s Preferred Route Option, which identified a number of challenges. As a result of the challenges identified, many of which are difficult to mitigate, three additional route options were developed to be considered alongside the Community’s Preferred Route Option within the DMRB Stage 2 assessment. The design for each route option was developed by Transport Scotland to the same level of detail as is required for all major trunk road projects, to allow the Scottish Ministers to make an informed decision with the confidence that it can be delivered successfully through the planning process. More detailed information about key aspects such as buildability, noise and other environmental impacts, traffic and economic impacts were investigated to ensure a robust and deliverable design was identified. During this period Transport Scotland consulted with stakeholders and people who may be directly affected by the community’s preferred option.
