RPS acted as lead designer for Transport Scotland on this DBO project. This scheme is part of the wider A9 Dualling Programme to improve the A9 between Perth and Inverness and is the first section of the overall programme to be dualled. The project comprised 7.5km dual carriageway, 7.5km non-motorised user route, and six large underpass structures.

The A9 project presented a number of challenges to our team. The proposed route ran through the Cairngorms National Park in the Highlands of Scotland and also crosses through Alvie Site of Special Scientific Interest and a tributary of the River Spey Special Area of Conservation. This presented significant challenges to our design and ecological teams.
Other project challenges included relocating the non-motorised user route off-line in order to reduce the width of the underpass structures and introducing sections of split-level carriageway to maximise the utilisation of site won fill material.
RPS delivered for Transport Scotland design elements, developed on a BIM platform to include:
RPS also provided ecological monitoring services which involved monitoring environmental compliance of the scheme and developing good practice, working closely with on-site teams and external regulators.
