On this section the unit costs show a slight advantage in favor of doing the work with State forces. Conditions were practically the same as on the Clatskanie-Westport Section in Columbia County--the State paying higher wages than the contractor, but the contractor having the disadvantage of more unfavorable weather conditions. The main advantage in the State doing this work was gained by having better control of the organization and more direct supervision of the work. The original intention was to complete all macadam 16-feet wide but the increased cost of labor, supplies, etc., made it necessary to reduce the width of the macadam to nine feet so as to complete the full distance with the money available.
