A joint effort between emergency personnel, sheriff's office deputies, county road crews and civilians kept Dawson County roads safe last week after a severe storm blew through the county, knocking down trees and leaving thousands without power. During the height of the storm the night of March 21, emergency personnel estimated that about 50 city, county and state roadways were blocked. Emergency Services Chief Lanier Swafford said during Thursday's county commission meeting that of the roads that could be cleared, and that personnel were aware of that were blocked, the majority of those were cleared in a four-hour period.
