This is how Russia keeps highways free of snow

A member of an emergency services special unit fires a shell towards the upper slopes to clear snow buildup above the Transcaucasian highway.

The shelling took place some 110 km (68.4 miles) from the southern Russian city of Vladikavkaz this past weekend. Avalanches are a constant threat on the road which is the only route connecting Russia to South Ossetia.
