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.
The 2.26 miles of macadam cost the County a total of $19,280.35. A total
of 4,208 cubic yards of rock was placed, making the unit cost $4.56 per
cubic yard. Crushed trap rock was secured from a quarry near the city
limits, and suitable binder material was found near at hand. The
engineer in charge was R. H. Baldock of the State Department.
