Rainier-Goble Macadam
In Columbia County the State Highway Department laid twenty-four and one-tenth miles of sixteen foot waterbound macadam and four and two-tenths miles of nine foot waterbound macadam between Goble and the Clatsop County Line. Of this the [Rainier-Goble Section] was taken over from the contractors, Clark & Dibble, after being partly completed. This was done in order to facilitate the work and get the road open for traffic before the rainy season.
While the work done by the State on this section cost more per cubic yard than the contractor was originally receiving, the actual difference in cost for the job was not sufficient to justify the Department in allowing the contractor to proceed with the work which would have entailed leaving the road closed to traffic for another winter.

Goble Macadam Work
A contract was awarded to Warren Construction Company September 4, 1917, for macadamizing the Goble Cut-off on a basis of cost plus ten per cent.
Columbia County has a quarry on the old road about three-fourths of a mile west of Goble, which was equipped with complete crushing outfit and arrangements were made by the contractor for the use of this equipment and all the rock for this job was crushed and hauled from this quarry.
