A83 Through Arrochar | Carriageway Improvements

through the village of Arrochar
20th of May 2026, 7:00pm to 3rd of June 2026, 6:00am

BEAR Scotland, on behalf of Transport Scotland, will carry out a second phase of overnight carriageway resurfacing works on the A83 trunk road through the village of Arrochar from Wednesday 20 May.

These works will be carried out between the hours of 7pm and 6am each day, and are expected to be completed by the morning of Wednesday 3 June. There will be no works on Friday or Saturday nights.

To protect the workforce, overnight closures will be in place from the Rowantree Cottage B&B to the River Loin Bridge, with amnesties provided to allow road users to pass through the site safely at 8pm, 9pm, 10pm, 11pm, midnight, 1am, 2am, 3am, 4am and 5am.

Traffic management measures will be removed outwith working hours. However, temporary speed restrictions will remain in place throughout as traffic will be running on a temporary surface with no road markings.

Access through the works sites for emergency services will be maintained at all times.

Steve Taylor, BEAR Scotland’s North West Design Manager said: “These works will help restore the condition of the road surface of this section of the A83, greatly improving driving conditions.

“Our teams are committed to executing these works quickly and with safety as our top priority. We thank the local community and road users for their patience while we complete the improvements.

“To minimise delays, we recommend that motorists plan their journeys in advance by consulting the Traffic Scotland website for real-time travel updates.”
