The maintenance of county roads is handled by employees of the Secondary Roads Department. Responsibilities of this division include roadway maintenance, snow removal, tile crossing repair, bridge, and culvert repair, ditch cleaning, dust control and roadway signing. Additionally, the county employs skilled mechanics to ensure that equipment is maintained and ready to use when needed.

Dust Control

Dust control may be placed on gravel roads within Benton County at the expense of the resident. Benton County personnel can apply one form of control (MC-70) through the county but other forms are available through private businesses.

In order to place any dust control on a road, a resident must obtain a Dust Control Permit. MC-70 permits are available through the Benton County Engineer's Office and the private companies will have permits for their dust control. After obtaining a permit, county personnel will prepare your road for dust control and will not blade through the areas as long as it is maintained in an acceptable manner by the resident. Permits are normally valid until the end of October when Benton County starts to ready the roads for winter. Permits may be mailed, faxed, emailed, or dropped off at the office, and must contain proper payment to be considered valid.

MC-70 dust control may be exempted the following year after applied if still in good condition. The dust control must be maintained in an acceptable manner by the resident. It can only be exempted for one year and residents must obtain a permit for exemption. These permits are due at the same time as the new dust control permits. 

Roadway Maintenance

Benton County Secondary Roads Department employees are tasked with building and maintaining the Secondary Roads System and its right-of-way (ROW).  Throughout the year our workers complete numerous and diverse projects including reshaping ROW, building driveways, patching hard-surfaced roads, building bridges and spreading rock on our 925 miles of gravel roads.

Benton County is divided into 13 maintenance zones with each zone having a maintainer operator.  These county employees are responsible for the blading and maintenance of the roads within each zone.  Gravel roads are maintained through rock application by county personnel which is then distributed on the road via the areas maintainer operator.
