In 2011 Scottish Government Ministers announced their commitment to dual 80 miles of road between Perth and Inverness. 

This forms part of the Scottish Government’s plan to connect all Scotland’s cities with a high-quality transport system by 2030. 

At £3 billion, this complex and challenging civil engineering project will be the largest transport investment in Scotland’s history. 

The A9 is the longest trunk road in Scotland, with the Perth to Inverness section forming 177km (110 miles) of the 433km (269 miles) total. 

Benefits from the A9 dualling will include reduced journey times, improved operational effectiveness, less driver frustration and safer roads for users and local communities. 


The route has been split into 11 projects. These are listed below:
