In 1917 the Highway Department constructed with its own forces and
equipment 1.8 miles of concrete pavement from Sheridan east on the
Sheridan-McMinnville Road. This pavement was 16 feet wide, 61/2 inches
thick at the center and 51/2 inches thick at the edges. The mix used was a
1:11/2:3.
In connection with the paving there was a considerable amount of
grading, the total expenditure for grading, culverts, etc., being
$5,651.70. The cost of the 1.8 miles of paving was $31,432.99, the unit
cost being $1.82 per cubic yard.
Yamhill County co-operated in the payment for this work to the amount of
$10,000.00. A complete statement of the costs on this work is given
below.
