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.
This was done by Oscar Lindstrom on a basis of cost plus ten per cent.
A half-viaduct seventy-five feet in length was built containing fifty-three cubic yards of concrete and 4,100 pounds reinforcing steel, with standard bridge railing for guard fence.
Two hundred and fourteen linear feet of rubble masonry walls were built on a slope of three-fourths to one, and standard bridge railing placed on top for guard fence. These walls contain 438 cubic yards of rock.
A reinforced concrete crib forty-one feet long, fifteen feet high and seven feet wide was built and filled with large rock. The members were cast on the dock in Rainier and hauled to the location. A reinforced concrete slab on solid earth foundation was used for footing, on the required angle to give the crib a batter of one-fourth to one.
The total cost of the Prescott Hill improvement was $9,039.86.
Goble Creek Bridge
A ninety-foot reinforced concrete bridge was built over Goble Creek on the Columbia River Highway about one-half mile east of Goble. This bridge has a pile foundation which was put in by the Warren Construction Company on a cost plus basis for $1,583.32. The superstructure was built by Lindstrom and Fiegeson on a unit price basis. The cost of the structure complete was $5,907.14.
The engineering work in connection with this work was handled by H. C. Compton, resident engineer, on the Goble Section, and the inspection of the placement of steel and pouring of concrete was in charge of L. M. Huggins.
