The Sheridan County Public Works Department plans apply dust suppressant to Red Grade Road from the Springs to Sand Coule next week.
The plans are subject to change depending on the weather.
County officials said people should use caution when driving on Red Grade, which is also known as County Road 26, and use alternate routes where possible. There may be delays during the application process. People who cannot find an alternate route are advised to wash their cars as soon as possible after traveling through the application area.
