After grading the 1.82-mile section of the Oregon-Washington Highway west of Heppner, and .44 miles east, Morrow County proceeded to surface with a standard waterbound macadam. This work was done on a force account basis by the United Contracting Co. and Warren Construction Co. The work was completed and opened to traffic in July, 1918.
