If the county court in its order calling an election under ORS § 370.031 designates the particular roads to be built or improved by the money raised by the sale of bonds, the county court shall not use any of the money raised upon any other road or for any other purpose than those mentioned in the order. If the order does not designate any particular roads to be built or improved by the money raised, then the county court may expend the money raised from the sale of the bonds to build, improve or maintain such permanent roads within the county as the county court considers proper. [Amended by 1983 c.350 § 234]
