The old county road between Wolf Creek and Grave Creek on the Pacific
Highway in Northern Josephine County, passed over two summits about 250
feet above the valley levels of Grave and Wolf Creeks, giving four long,
heavy grades, in some places the grade being as high as 25 per cent.
These two summits were about one mile apart, and the nature of the
ground was such that support could be had for a practically level grade
between the two.
With a view to locating this level grade between the summits and
developing five per cent grades down the sides, a preliminary survey was
made in October and November, 1916, under the direction of Mr. S. H.
Probert. This survey was worked up in the office during January and
February, 1917, and in July, 1917, the projected location was staked on
the ground by Mr. C. C. Kelley, locating engineer.
The length of the survey was 4.9 miles, the terminal points being about
three-quarters of a mile east of Wolf Creek Post Office and about
three-quarters of a mile west of the Grave Creek Bridge.
The construction of this section, which was undertaken in the fall of
1917, is described in another article in this report.
