Photograps from the Ministry of Public Works, Public Roads Office.
In 1923, Hans and Even Øveraasen of Norway constructed an early snowplow for use on cars. This proved to be the start of a tradition in snow-clearing equipment for roads, railways and airports, as well as the foundation of the company Øveraasen Snow Removal Systems.
