Skye road restored after 300-tonne landslide with rock armour and drainage works

Around 300 tonnes of rock, soil and debris were removed from a key road on the Isle of Skye after a landslide blocked the route near Uig, triggering a rapid programme of slope stabilisation and drainage improvements before traffic could safely return.

The failure occurred at Idrigill Bends on the A855, which encircles the Trotternish Peninsula in northern Skye. A substantial volume of material detached from the roadside slope and spread across the carriageway, completely blocking the route. The landslide, which was captured by CCTV from a nearby property, caused no injuries but forced motorists onto a diversion of approximately 40 miles.

Initial clearance focused on removing the fallen material and making the area accessible, but inspections showed that clearing the carriageway alone would not be enough to safely reopen the road. Attention therefore shifted to the condition of the remaining slope and the movement of water through the affected area.

Crews progressively removed loose and unstable material before installing large rock armour along the damaged bank. The rock provided additional support to the affected ground and helped establish a more stable slope profile following the loss of material.

Drainage formed another major part of the response. Water was redirected away from the affected area, existing drainage was improved and roadside gullies were cleared to restore their capacity. Specialist equipment was brought to the site to clean the drainage system while engineers continued inspecting the slope during the repair works.

These measures were particularly important because the landslide followed heavy rainfall. Where water accumulates within a roadside slope, saturation can contribute to loss of stability and increase the likelihood of further movement. Restoring drainage therefore addressed one of the conditions affecting the site rather than simply removing the visible consequences of the failure.

Regular safety inspections continued throughout the closure as the debris clearance, drainage improvements and rock-armour installation progressed. Road crews, engineers, contractors, traffic management teams and emergency services worked together while arrangements were also made to maintain essential access for local schools and communities.

The A855 was eventually reopened to all traffic after the stabilisation and drainage works were completed and the site was considered safe.

Although the landslide involved a relatively short section of road, its impact was significant because of Skye's limited alternative routes. The response illustrates why landslide recovery often extends well beyond clearing debris from the carriageway. Restoring a route safely requires understanding what remains above the road, controlling water around the failure and stabilising the exposed ground before traffic can return.
