Routt County begins annual mag chloride dust suppression on roads

Workers with Routt County Road and Bridge will begin the county’s annual Dust Suppression Project on Monday.

This five to six-week project will start in Hayden, move east to Steamboat Springs, then south to Oak Creek, and finish north of Routt County Road 44. The county operation uses magnesium chloride on approximately 200 miles of Routt County gravel roads to suppress the dust generated by roads in the county with higher traffic, according to the county. 

County officials recommend residents traveling those roads wash their vehicles, including the undercarriage, to remove any magnesium chloride residue.
