Six vehicles were damaged after rocks and debris tumbled onto a busy road running along the banks of Loch Ness.
One lane of the A82 was closed between Drumnadrochit and Invermoriston after rocks and soil fell from an embankment above the Inverness to Fort William road.
The debris fell yesterday after a tree became dislodged on the slope near Alltsigh overnight.
A police spokesman confirmed six vehicles suffered damage to their tyres after driving through the debris at about 7.30am yesterday.
Teams from Bear Scotland and Forestry Commission Scotland were called to the scene and worked to remove two trees from the slope.
The debris itself was cleared shortly after it fell onto the carriageway but the northbound lane was cordoned off under temporary traffic lights.
A full geo-technical survey of the slope is due to be carried out today by Bear Scotland to check if any further work is needed.
Eddie Ross, Bear Scotland’s north west representative, said: “Our incident support unit responded to reports of debris on the route very quickly and worked to ensure the route was safe for motorists.
“The A82 remained open at all times while we worked closely with Forestry Commission Scotland to safely remove the debris and trees from the slope and will aim to get both lanes open to traffic as soon as possible.
“Like other trunk roads in the region, the A82 is part of an ongoing programme of rock slope inspections with any necessary works identified thereafter. However occasions such as today’s can arise and we work closely with operational partners to ensure that the road can be safely opened as quickly as possible.”
Graeme Prest from Forestry Commission Scotland’s local team added: “This incident wasn’t on the national forest estate but it perfectly illustrates why we are having to carry out our steep ground harvesting programme along the A82.
“This was a small tree and a small amount of debris, primarily caused by water ingress and frost heave. Our steep ground programme will help ensure that this doesn’t happen on a bigger scale.”
