Clatskanie-Delena Macadam

The section extending from a point three miles east of Clatskanie to a

point two and one-half miles east of Delena, known as the

Clatskanie-Delena Section, was completed by L. O. Herrold on a basis of

cost plus ten per cent. This work consisted of eleven miles of sixteen

foot waterbound macadam, one and one-tenth miles of nine foot waterbound

macadam and all necessary grading, drainage, etc. The foundation on part

of this section was very poor and 10,233 cubic yards of rubble base was

used in order to make satisfactory foundation for macadam. While this

increased the cost of the macadam, it was the only way in which a

permanent foundation could be secured on this section. P. M. Hall-Lewis

was resident engineer on this work.
