On July 4, 1918, a contract was awarded to A. D. Kern of eighteen miles
of gravel surfacing between Hood River and the Multnomah County Line on
the basis of cost plus fifteen per cent on labor and supplies and twelve
and one-half per cent on equipment; provided, that no percentage should
be paid on any cost over $50,000. This work also includes the building
of shoulders on the one mile of pavement built by S. Benson in 1916
adjacent to the Multnomah County Line. The gravel for this work was
taken from pits at Cascade Locks, Herman, Sonny and Hood River, was
loaded by steam shovels, screened at two of the pits and hauled by auto
trucks. As a result there is now a gravel surface between Hood River and
Cascade Locks. A total of 23,396 cubic yards was placed upon the road at
an average cost of $2.88 per cubic yard which represents total cost of
excavating, screening, hauling, spreading and rolling.
