For several years, now, the unpaved roads in Sheridan County have been treated with chemicals to suppress the dust. County roads supervisor Rod Liesinger says the treatments also extend the life of the roads.
He said about $750,000 will be spent to treat nearly half of the 550 miles of county roads, coming from the capital facilities tax fund.
He said the road treatment program has been ongoing since what he called the busy coal-bed methane years when there was significantly more traffic on the roads. The chemicals are applied in a two-part process.
He said they treat the roads in the early spring, because less water is needed in cooler temperatures, and plan to be done by the middle of June.
