A complete description of the paving of the 15.7 mile section of the
West Side Highway between the Multnomah County Line and Newberg is given
in the Chapter devoted to Washington County. It should be mentioned
here, however, that 3.2 miles of this pavement is within Yamhill County,
and was built by the State at a cost of $57,500.00. The construction of
the subgrade was paid for by Yamhill County, part of it having been done
by County forces and the balance of it by the paving contractor under a
cost plus 10 per cent agreement with the County. For the work done under
this agreement, the contractor was paid $6,153.05.
