The road system of the county is divided into two (2) classes, primary and secondary roads. The secondary road system is made up of farm-to-market roads and local secondary roads.

The primary road system is under the supervision of the state highway commission represented by a maintenance superintendent. Funds for the construction and maintenance of the primary road come from the automobile license fees, federal aid and the gas tax.

The secondary road system is under the supervision of the board of supervisors and the county engineer. Funds for these roads come from tax levies and secondary road fund and from the county's share of road use tax.

The county's farm-to-market system of roads comprises about 242.394 miles connecting the different towns of the county and also connecting with roads leading into other counties. This system is under the supervision of the county engineer and the board of supervisors for construction and maintenance.
