The Environment, Development and Infrastructure Committee of Argyll and Bute Council considered a report on the progress achieved so far at this month’s meeting.

The severe weather event which took place on 7 October 2023 caused a landslip that deposited roughly 6,000 tonnes of material over a 200-metre section of the A816, which closed the main route between Oban and Lochgilphead. 

This prompted the construction of a temporary bypass to keep the area connected.

Last year, the EDI Committee agreed to invest £1.1 million in developing a business case to deliver recommended options, a budget estimate and outline programme for providing permanent repair.

Detailed investigations have shown that widening the temporary bypass is an unsafe long-term option. 

Intricate and evolving geotechnical risks make that option unviable. 

But the Options Report identifies the preferred option as a new, permanently realigned section of road, built to modern standards. The present estimated cost of the permanent construction works is estimated to be £7.25m–£8.5m, with an intervention estimate of roughly £14.8m.

The development of the project will be informed by the Environmental Impact Assessment, further ground investigation and planning requirements. 

The council is currently targeting delivery of the project between 2029 and 2032, subject to the outcome of this work, the necessary planning, consents and other approvals, market test and funding being secured. 

The project will deliver a safer and more reliable route for residents, businesses and visitors. The project will also strengthen the road’s resilience to future severe weather events. 

Looking ahead, the council will continue to maintain and monitor the route, while also enhancing traffic management arrangements to help keep road users moving safely through the area. 

Part of these efforts include working with SSEN and the landowner to install a permanent power connection to tackle the vulnerabilities associated with the traffic lights.

Councillor John Armour, policy Lead for Roads Transport and Amenity Services, said: “We are still fully committed to delivering a safe, resilient and long-term solution for the A816 at Bealach Mor. The progress being made through the Strategic Outline Business Case is a major step towards finding the best option for the future of this key transport corridor.

“We recognise the importance of the A816 to communities across Argyll and Bute and appreciate the patience and understanding shown by road users as we work towards a permanent route built to current standards will serve the area for decades to come.”
