ON THE COLUMBIA RIVER HIGHWAY NEAR GOBLE IN COLUMBIA COUNTY.
GRADED AND MACADAMIZED IN 1917 AND 1918
The material for the east approach was obtained by trimming up the cut left by the railroad company.
A contract for grading the cutoff was awarded to the Warren Construction Company, August 7, 1917, and work started in July, 1917. From the east end of the section to Ruben, about one mile in length, the material was handled by teams. Rock work at Ruben and at Goble was sub-let to station men. The fill across the flat between Ruben and Goble was made from side borrow, by using a steam hoisting engine, with boom and clam shell bucket. This work was done in the fall and winter and the material was light loam and sand and very wet, and did not pack very solid in the fill, therefore a strip of rock sixteen feet wide and one foot in thickness, taken from the rock cuts at either end, was placed on the fill and rolled thus making a solid base for the crushed rock macadam.
The engineering work was done by A. F. Pratt, resident engineer and W. E. Eddy, assistant state highway engineer, until October 1, 1917, when it was taken over by H. C. Compton, resident engineer, under the supervision of Chas. H. Whitmore, assistant engineer.

Rainier Hill Grading
On July 30, 1917, a contract was entered into with A. L. Clark of Rainier for the widening of the Rainier Hill Section, a section two and two-tenths miles in length, located just west of Rainier. This work was let under a unit price contract, but the nature of the work was such that a considerable part of it could not be fairly measured and paid for on a unit, and on this part the contractor was allowed cost plus ten per cent. The total cost of this improvement was $6,350.61. A detailed cost statement follows:
