Transport Scotland has published draft orders for the latest part of the A9 dualling programme - an 8.4km section from Pass of Birnam to Tay Crossing.
The estimated cost range for the scheme, which includes new grade-separated junctions at Birnam and Dalguise and a new roundabout at Dunkeld, is £427-£486m based on 2023 prices.
The draft Orders, published 30 May, mark the start of the statutory consultation period for the works, which also include a new car park for Dunkeld & Birnam railway station and an underpass allowing step free access to both station platforms for locals and visitors.
Transport Scotland is holding public exhibitions on 11 and 12 June 2025 in Birnam Arts Centre, but an online exhibition and Story Map, which includes information on the plans for the route, is now live.
Cabinet secretary for transport Fiona Hyslop said: 'The route option selection for this challenging scheme was the subject of a co-creative process with the local community.
'I would like to take this opportunity to thank the local community for their work.
‘Local communities and road users will have the chance to see and comment on our plans for this challenging section of the A9 at face-to-face public exhibitions in June and via an online exhibition which will go live today.
‘We are committed to delivering a safe, reliable, resilient and dualled A9 between Perth and Inverness in line with our published delivery plan, which anticipates dualling to be operational by the end of 2035.’
