During 1917 and 1918, the State Highway Department in co-operation with
Washington County has completed the grading, bridging and paving of the
West Side Highway across that County. This work has involved the grading
and paving of 12.5 miles and the construction of three bridges and one
undergrade railway crossing. On this work, when final payments are
complete, the State will have expended $292,000.00 and the County will
have expended $10,000.00.
In addition to this construction, the Department has made surveys
between Beaverton and Hillsboro and between Forest Grove and Gaston, and
has furnished the County engineering services in connection with the
grading of these two sections.
