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.
