Both of these roads were passable for autos only about three months during the dry season. The grading of this section was partly completed by the County under supervision of Mr. Bowlby, State Highway Engineer in 1914. This section being a very important link in the Columbia River Highway and no funds being available from County or State funds during 1915 or 1916, S. Benson decided to advance the necessary funds to make this section passable. About four miles of grading was completed between Inglis and Delena, leaving only the building of bridges to open this section. This work was later macadamized by the State. The engineering work was done by A. K. Grondahl. A bill was passed by the 1917 Legislature refunding to Mr. Benson $20,978.22 which is a large portion of the amount expended by him. COST STATEMENT Clearing and grubbing $ 1,265.80 Grading--labor and teams 17,124.07 Explosives 2,275.31 Pipe culverts 313.04 ---------- Total $20,978.22 Prescott Hill Section This section of the highway was built along the steep hillside, several slides having occurred narrowing the roadbed in some places to about eight feet and making it very dangerous, it was necessary to build several retaining walls, half viaducts and guard fences.
