A830 Arisaig to Loch Nan Uamh

Client: The Highland Council
Value: £22.8 million
Location: West Coast of Scotland

Scooping the prestigious “Saltire Society Award for Civil Engineering”  and a "Commendation" in the “Environmental Sustainable Construction” category, this project involved the upgrading of the last section of single track trunk road in the UK.

Works comprised the design and construction of approximately 7.5km of A830 Trunk Road between Arisaig and Loch Nan Uamh in a highly scenic area on the west coast of Scotland.

A large section of this project is located in a Special Area of Conservation (SAC) which means that very stringent environmental restrictions and regulations were employed throughout the site, with additional requirements enforced by the Scottish Environment Protection Agency to control run off during earthworks.

The project involved large quantities of earthworks (150,000 cubic metres of peat and 350,000 cubic metres of rock) and the construction of a number of reinforced concrete arch structures to cross the burns and watercourses at Larachmore, Brunery, Borrodale and Beasdale, along with a structure to support the new road at Larachmore Gardens.
