The A9 Dualling Programme continues to gather pace as Transport Scotland confirms the shortlist of contractors for the fifth construction section, covering approximately 4 miles between Pitlochry and Killiecrankie.

This £205 million project (estimated at Q2 2025 prices) will upgrade the route to dual carriageway and is a key part of the Scottish Government's commitment to completing this vital infrastructure improvement.

The three contractors invited to participate in the next stage of the competition are: Balfour Beatty Civil Engineering Ltd; Kier Transportation Ltd; Wills Bros Civil Engineering Ltd

Cabinet Secretary for Transport Fiona Hyslop stated that the government is continuing to meet the planned milestones for the delivery plan. The next phase involves an intensive period of dialogue where each contractor will refine their outline design proposals, driving value for money for the Scottish taxpayer.

The extensive engineering works include building or upgrading nine bridges, among them a substantial new crossing of the River Tummel alongside the existing Tummel Bridge, and a new rail bridge over the Highland Mainline Railway. The design also incorporates improved access and safe crossing points for non-motorised users, including enhanced routes for the Rob Roy Way.

Transport Scotland expects to award the contract in Autumn 2026, following the submission and evaluation of final tenders. The new dual carriageway section is anticipated to be operational by the end of 2030. When this section is complete, almost 50% of the A9 between Perth and Inverness will be dualled. The contract will be delivered using the amended NEC4 Engineering and Construction contract and will feature a carbon reduction fund, which provides financial support to the successful contractor for achieving otherwise uneconomic carbon emission reductions.
