Major rockslope stabilisation works are progressing at A828 Ledaig following a series of rockfall incidents at this location. The project began in January 2025 and is being delivered to improve long-term safety and resilience along this key route.
The works include vegetation removal, rock scaling, installation of netting to mitigate against rockfall, and targeted intervention for any unstable material.
Following increasing rockfall activity and detailed inspections carried out in late 2024, areas were identified as showing significant deterioration since the previous assessment earlier in the year.
Emergency boulder removal works were undertaken in November 2024 where airbags were used to safely dislodge unstable rock which posed a risk to the carriageway below. Steel plates and a stone bund were utilised to protect the road and underground utilities.
The main rock face stabilisation programme was subsequently brought forward in response to the rockfall events to ensure public safety and minimise future disruption.
The main rock face works commenced in January 2025 and resulted in 4925m² of rock netting being provide and 1196 m of rock bars installed to help stabilise the natural rock.
Environmental and geological issues slowed progress on site and resulted in the requirement for additional interventions, leading to a significantly longer programme of works than originally expected.
Initially, issues with roosting birds impacted progress despite steps being taken in advance to minimise disruption to local wildlife, including the installation of bird nesting boxes and the use of sound and visual deterrents.
Furthermore, due to the complex geology at this location, developing a safe and effective solution required detailed assessment and careful planning. As our teams have gained safer access to the slope, additional areas of instability have been identified. Expanding the project scope is therefore essential to address these hazards properly and to ensure the long‑term safety and resilience of this key route.
The project team is currently developing designs to address these newly identified areas, which will involve further rock removal and stabilisation.
Whilst a solution is finalised, works have continued on site, with tree felling and the installation of two temporary catchfences completed on the northern side of the rock face, and a new secondary duct installed within the closed lane to ensure continuity of services.
The next phase of essential rockslope stabilisation works is currently underway and is expected to last for up to six months. This includes the removal of loose rock and further slope stabilisation using netting and rock anchors.
Night-time working is required during certain safety-critical activities, with traffic stopped in both directions for short periods of up to 10 minutes to allow more extensive rock removal. This has progressed well with two large rock blocks successfully removed from the slope, a significant step forward in improving the safety of this section of the A828 trunk road.
There are currently three smaller areas of rock remaining to be removed. However, overnight works are currently paused due the identification of bird nesting activity within the overnight works area. Our environmental team are monitoring closely to ensure compliance with the Wildlife and Countryside Act 1981.
Daytime works can continue as these activities can be safely carried out at a suitable distance from the nest.
To facilitate this work and ensure teams can safely access the area, temporary traffic lights remain in place. The road remains safe for use, and the traffic management allows us to maintain access to the slope while the design for the remaining works is completed.
Regular roadside inspections are being carried out as part of ongoing monitoring at the site.
Details will be shared through this website and with the community council as soon as they are available.
The A828 Ledaig slope has a long history of rockfall activity, and the works being undertaken are essential to ensuring the long-term safety and reliability of this important route.
While unexpected conditions have required an expansion of the project scope, these findings are typical for complex rock environments and can only be fully inspected and assessed once protection systems are in place.
We remain committed to completing the works as efficiently and safely as possible, and minimising disruption to residents, businesses, and road users.
Further information will be issued once the additional design work is complete and the programme for future activity is established.
