RADIO IS LATEST AID IN BATTLE AGAINST SNOW
Radio is the latest innovation in the battle between science and snow. Twenty fixed radio stations and 16 portable units are being operated by the Washington State Department of Highways at Olympia in the effort to keep winter traffic on the move.
Because plowing must be carried on in remote mountain regions where wire communication is unavailable or unreliable, all rotary plows have been equipped with two-way radio installations in order that they may keep in constant touch with the maintenance offices of the highway department, receiving instructions and broadcasting weather reports or calls for help. Shop clerks and plowmen are licensed radio operators.
