The Kincraig to Dalraddy project was the first section of the A9 to be dualled as part of the A9 Dualling Programme. This involved widening the existing road from single to dual-carriageway.
From Kincraig at the southern end of the project, the carriageway was widened to the west of the existing A9 before crossing over to the east side to complete the northern section at Dalraddy. This project included the construction of four accommodation underpasses and one large culvert replacement.
The contract for the design, construction and maintenance of the Kincraig to Dalraddy section was awarded to a joint venture of Wills Bros Civil Engineering Ltd. and John Paul Construction in June 2015.
The road became fully operational on 30 September 2017. While the construction of the dual-carriageway is now complete, the contractor may at times be required to carry out snagging and landscaping works.
The next section of the A9 Dualling Programme to be constructed is the Luncarty to Pass of Birnam Project.
