Under construction
Upgrade to existing road for use by all traffic
£ 3bn
Transport Scotland
Region: Scotland
222 km
137 miles

A huge project to upgrade the many lengthy single two-lane sections of the A9 between Perth and Inverness to provide a continuous dual two-lane road. The upgraded road will be provided with grade-separated junctions, with new interchanges built to replace the busy Keir, Broxden and Inveralmond roundabouts.

There has for several years been a prominent campaign to improve safety on the A9 by dualling it, but critics argue that the multi-billion pound price tag is unjustifiable given that much of the road to be upgraded carries fewer than 10,000 vehicles per day.

Transport Scotland have divided the single two-lane parts of the route into twelve sections. Kincraig to Dalraddy is the first of these to be built.

2 March 2009 Construction is due to start on two relatively small schemes within the next few weeks. A stretch of road near Carrbridge is to be widened to S2+1. This will offer northbound drivers a safe overtaking opportunity, breaking up a very long stretch of single carriageway road. Construction is also to start on a grade separated junction at Bankfoot, eliminating the need for southbound traffic to make right turns either onto or off one of the busiest sections of the A9.
4 June 2009 The overtaking lane at Carrbridge is now complete.
10 June 2009 Construction at Bankfoot was underway at the start of May, with a section of the A9 restricted to 30 mph.
13 August 2009 Work seems to be nearly finished. 'No U-turn' signs and solid white lines are now in place.

9 March 2011 Draft orders for the Slochd 2+1 improvement were published today. The scheme involves the construction of a new overtaking lane at Slochd, north of Aviemore. The total scheme length is 3.8 km. Construction is expected to start in 2012/13, subject to funding.
19 May 2011 BBC News reports that Transport Scotland have said, subject to agreement, work could start within a month to reopen northbound overtaking lane on the Moy 2+1. This has been closed since 19 November 2010, following concerns about traffic crossing to a junction near the end of the lane.
26 July 2011 Following widespread safety concerns, the recently-completed northbound overtaking lane at Moy is currently being reconfigured as a southbound overtaking lane. The repainting is expected to be finished in a few weeks.
27 September 2011 The Crubenmore northern extension is now open to traffic.
6 December 2011 The Scottish Government's Infrastructure Investment Plan, released today, includes a commitment to complete the dualling between Perth and Inverness by 2025.

10 September 2015
29 January 2016 Public exhibitions were held on 26 and 27 January 2016 detailing progress with development work to dual the 10.2 km section from Pass of Birnam to Tay Crossing. The exhibition material, including details of the route options, can be downloaded from the Transport Scotland website.
