The Telegraph UK reports that the avalanche was deliberately triggered.
The president of municipality of Saxon, Léo Farquet, said: "It's an avalanche was triggered deliberately to secure the road, we do it every snowfall."
It is a procedure done to minimise the risk of uncontrolled avalanches taking place, which puts lives and properties at risk.
The road has since been secured and has been cleared of snow.
