Traffic restrictions will be brought in along sections of the A82 from this week to facilitate the movement of two new Super Grid Transformers to SSEN Transmission's Creag Dhubh substation in Argyll.
The staged deliveries, due to take place between Thursday 4 June and Thursday 18 June, are part of a carefully co‑ordinated logistics operation. The transformers are being shipped from Poland to Clydebank before continuing by road to the substation site near Cladich, a journey of around 90 miles.
Super Grid Transformers are among the largest assets on the electricity network, typically weighing several hundred tonnes. They step voltage up or down to enable the efficient transmission of power across the grid.
Moving equipment of this scale requires specialist transport, detailed planning and robust traffic management. SSEN Transmission has worked closely with Transport Scotland, BEAR Scotland, Police Scotland and local authorities to organise the operation and limit disruption as far as possible.
To allow the heavy loads to safely cross infrastructure near Crianlarich, temporary overnight closures are planned on a short stretch of the A82 between Crianlarich and Tyndrum at:
- Sunday 7 June to Monday 8 June (10pm to 5am)
- Tuesday 16 June to Wednesday 17 June (10pm to 5am)
This will involve closing the A82 at Inverherive at the Herive Burn so the convoy can pass safely. A purpose-built bridging deck will be installed over the existing bridge to provide extra reinforcement during the crossing. Diversions and signage will be in place, and access for emergency services will be maintained.
Further traffic management will support the wider delivery programme. An inside-lane layby between Firkin and Rossdarroch on the A82 south of Tarbet will be closed from Tuesday 2 June to Friday 19 June, with temporary overnight traffic signals in use while the layby is operational to manage flows.
Temporary parking restrictions are also scheduled on Dumbarton Road on Thursday 4 June to Friday 5 June, and Wednesday 10 June to Thursday 11 June, to ensure the safe passage of delivery vehicles.
Drivers are advised to plan ahead, allow extra time and follow all signage and diversion routes. All dates remain weather-dependent and subject to ongoing co‑ordination with partner organisations.
Lee Biddulph, SSEN Transmission's Project Manager for the Creag Dhubh substation project, said: "We recognise these restrictions may cause some disruption and would like to thank local communities and road users for their patience while this complex operation is carried out.
"These transformers are critical to strengthening the local transmission network and supporting the growth of renewable energy in Argyll.
"Transporting components of this scale is a complex operation, which is why we have worked closely with our road traffic partners to plan deliveries carefully and keep disruption to a minimum, with all scheduled closures and restrictions dependent on weather conditions and coordination with key partner organisations.
"We encourage people to plan ahead, allow extra time for their journeys, and follow all signage and diversion routes to help keep everyone safe."
