The boards of county commissioners of the various counties shall have exclusive jurisdiction over the designation, construction and maintenance and repair of all of the county highways and bridges therein.
2. B. The boards of county commissioners are hereby authorized to establish road improvement districts as provided by law for existing roads in the unincorporated areas of counties. The boards of county commissioners may also have improvements made on existing roads in unincorporated areas of counties on a force account basis.
