About the A9 Dualling Programme

The A9 is regarded by many as the spine of the Scottish road network providing a vital strategic link in Scotland and carrying over 40,000 vehicles per day (over 65,000 people) along the Perth to Inverness section. The A9 Dualling Programme will upgrade approximately 129 kilometres of road from single to dual carriageway. The Pass of Birnam to Tay Crossing section forms 8.4 kilometres of the overall A9 Dualling Programme.
