A9 Dualling

Transport Scotland plans to upgrade this vital part of the A9 between Perth & Inverness to dual carriageway by 2025

The A9 is the longest trunk road in Scotland and this £3 billion project involves the challenging upgrade of 80 miles of single carriageway along the route between the cities of Perth and Inverness. In December 2011, the Scottish Government published its infrastructure and Investment Plan (IIP), which details plans for up to £60 billion of spending until 2030.The IIP sets out that the A9 between Perth and Inverness will be dualled by 2025, with a view to completing dualling of the A96, and thus, the dualled road network between all Scottish cities by 2030. 

  • ​economic growth

  • improved road safety

  • improved journey times and reliability

  • improved access to the tourist and recreation sites

  • improved links to pedestrian, cycling and public transport facilities

Speaking at the launch of the programme to dual the A9 between Perth and Inverness, Cabinet Secretary for Infrastructure and Capital Investment Alex Neil said:

"The A9 is the longest trunk road in Scotland and we have always said that delivery by 2025 was challenging but achievable. To put the sheer scale of the project in perspective - it is 16 times the length of the recently completed M74 and eight times the length of the M80 between Stepps and Haggs.

"I'm especially delighted to announce we are advancing the Kincraig-Dalraddy section to full dualling and doing so early. This development of the existing scheme will now provide overtaking opportunities in both directions, breaking up platooning and reducing driver frustration. Not only are we adding these additional safety benefits, we are also getting underway two years earlier than previously expected.

"Dualling each of these seven existing single carriageway sections represents a major project in it's own right. Each requires in-depth planning and design to ensure that we deliver the right scheme at the right price and each needs to keep impacts on communities, businesses and the environment to an absolute minimum.

"There is a great deal of detailed work to do and while we've taken into account the statutory processes in terms of delivery by 2025, the programme will develop and construction of some sections may overtake others as we progress with our plans.

"Later this year, we will also begin a rolling programme of regular engagement from Perth to Inverness to ensure the businesses and individuals who will be affected by the work over the next decade or so are kept fully informed and their important feedback is taken very much into account as we design, procure and construct."
