A9 Birnam to Tay Crossing

Scheme outline

Upgrade of the existing single-carriageway A9 between the end of the dual carriageway at Pass of Birnam and the bridge across the Tay near Dunkeld. The upgrade will provide dual two-lane carriageways as part of the wider programme of works to dual the whole A9 between Perth and Inverness.

This 10.2km (6.3 mile) section presents some significant engineering problems at Dunkeld, where the A9 passes between the town and its railway station, and numerous design options were developed to find a way to allow the A9 to pass through as an uninterrupted dual carriageway while allowing the village to remain connected to its station. These included sinking the A9 well below ground level, and in one option the construction of a cut-and-cover tunnel was considered, with the space above used for a new station approach and car parking.

This scheme is part of the A9 Dualling Perth to Inverness programme of works.
