The Preferred Route

Based on the findings of the DMRB Stage 2 route options comparative assessment, and considering feedback from the public and other stakeholders, the Preferred Route for the Pass of Birnam to Tay Crossing section of the A9 Dualling Programme is Additional Whole Route Option 3, Option ST2D.

A new pedestrian underpass, incorporating stairs and a lift, will provide a link for pedestrians from the car park to the railway station building and platform.
  • National speed limit (70mph) throughout.
  • Underbridge connecting the existing private access to Murthly Castle to the B867.
  • Grade-separated Birnam Junction just south of the existing B867 and Perth Road junctions with northbound entry and exit slips and southbound entry only slip.
  • A roundabout at Dunkeld Junction close to the current surface level (at-grade) providing connections between the A9, A923, A822 and the road to Inver.
  • Improved at-grade junction layout providing access to The Hermitage.
  • Grade-separated Dalguise Junction just south of the existing junction with the B898 with entry and exit slip roads in all directions.
