Snowplows also are becoming more efficient at clearing wider areas to prevent the need to repeatedly salt throughout a storm, officials said. The state transportation department has two new “tow plows” that attach to the back of snow plows and clear additional travel lanes by swinging side to side like a broom while dispensing salt. The tow plows are steerable and don’t require fuel. They’re estimated to cost $86,000 each and are used on I-70 in Howard County and I-68 in Garrett County.
