Construction work ramps up as fourth section of A9 Dualling contract is expected to be awarded

Scotland’s Cabinet Secretary for Transport, Fiona Hyslop, has announced her intention to award Wills Bros Civil Engineering Ltd the construction contract for the fourth section of the A9 Dualling Programme between Tay Crossing and Ballinluig.

The award of this £152.7 million contract (at Q2 2025 prices) will mark the achievement of another delivery milestone for the A9 Dualling Programme.  

The announcement of the preferred bidder is the final phase in the procurement process which, subject to the successful completion of a mandatory standstill period, will conclude with the award of the contract.

The £152.74 million contract is part of the Scottish Governments £257 million investment in the A9 Dualling: Tay Crossing to Ballinluig project. It is anticipated that the new dual carriageway will be operational by end of 2028 at which point 45% of the A9 between Perth and Inverness will be dualled, contributing to a safer, more resilient route for road users.

In addition to enhancing journey time reliability and safety for road users through dualling, the contract will deliver: a new side road network to improve access for the local communities of Dowally, Guay and Kindallachan; provision of a new overbridge at Guay South and a new underbridge at Kindallachan; and enhanced active travel routes and local path networks to improve access to and from the Highlands.  

The Cabinet Secretary for Transport Fiona Hyslop said: 

“This announcement demonstrates further progress on delivery of our plan to dual the A9 between Perth and Inverness. Our intention to award the contract for Tay Crossing to Ballinluig illustrates continued momentum in our delivery plan for dualling the A9 between Perth and Inverness.

“When work commences on this section, we will have active dualling works at both the southern and northern extents of the Programme’s corridor – a clear sign of the momentum behind our delivery plan.

“In addition to the improvements delivered through dualling, this investment will provide lasting social value to the communities and businesses local to these areas. We have seen already how contractors across the Programme are making a positive impact through our Social Value Programme, and I look forward to seeing further benefits delivered in the construction of this section.”
