This delivery plan will create a rolling programme of construction leading to the progressive opening of dualled sections.

It is expected that nearly 50% of the A9 between Perth and Inverness will be open as dual carriageway by the end of 2030, rising to 85% by the end of 2033 and 100% by the end of 2035.
