A830 Arisaig to Loch nan Uamh

What's involved?

Widening of single track length of A830 between Arisaig and Loch nan Uamh to allow for two way traffic.

Project benefits

A830 is a lifeline route to Mallaig and the Small Isles and the only existing one-way section between Arisaig and Loch Nan Uamh currently can be blocked by even minor incidents.

There are concerns for road safety, community safety due to emergency services access along the narrow road, and constraints on economic development.

Traffic management

Complex traffic management will be required involving various road closures for daytime and nighttime work on the existing railway bridges crossing the road and to allow the safe excavation of rock using blasting techniques adjacent to the existing road.

Environmental impact

There will be very complex impacts as the area is a Special Area of Conservation under the Birds and Habitats Directive and a National Scenic Area.
