  • Final phase of maintenance works resumes on Monday 5 February 2024 for 5 weeks
  • Single lane closure with two-way temporary traffic light system
  • Overnight road closures 6, 7 and 8 February and 7 March


Essential maintenance work is to resume on the A86 Allt A’Ghaill culvert, which supports the A86 trunk road, on 5 February 2024.

Previously scheduled to be completed early December, this project was unfortunately postponed at the half way stage, however we are now able to restart works to complete the maintenance of the bridge.

The project involves essential masonry repairs as well as road safety improvements. These consist of safety barrier upgrades, and minor carriageway widening and realignment. These works are being carried out to maintain the structure and avoid further, more extensive repairs in future.

The A86 carriageway will be reduced to one lane at the works site, with two-way temporary traffic lights in place for the duration of the scheme. This will allow teams safe access and protect workers and road users. The carriageway widening and surfacing works over the bridge will require four overnight closures of the A86. These are scheduled for 6, 7 and 8 February and 7 March from 8pm to 6am. A signed diversion route, detailed below, will be in place.

Ian Stewart, BEAR Scotland’s North West Representative said: “This essential maintenance project will see this culvert on the A86 fully repaired with added road safety improvements, allowing it to operate safely for years to come.

“We will do everything possible to complete this essential maintenance as quickly and safely as possible.  We thank all road users for their patience in advance and we encourage them to plan ahead by checking the Traffic Scotland website for up to date journey information and leave some extra time to complete their journeys.”
