Dualling the 15.6 mile (25.0 km) Dalraddy to Slochd project includes three new grade-separated junctions at Aviemore, Granish and Black Mount and four new left-in/left-out junctions together with a new  crossing over the River Dulnain and a new railway bridge over the Highland Main Line at Slochd Beag. It also includes new underpasses for non-motorised users and modifications and improvements to footpaths and cycleways.

The estimated total scheme cost for this project is £713m at April 2023 prices.

The Dalraddy to Slochd is expected to be a particularly challenging project to construct due to constraints caused by the local geology, proximity of the railway and areas of peat.

Details of the design and planning stage, including environmental mitigation measures, and relevant documentation such as made orders and environmental statements can be viewed on Transport Scotland's website.
