An effort has been made to secure Federal Aid in the construction of a section of the Portland-Tillamook Highway from Grande Ronde west. With this in view, the necessary surveys have been made, and it is expected that Federal Aid will be secured so that the construction may be undertaken during the 1919 season. Sheridan Paving--1917 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, 6½ inches thick at the center and 5½ inches thick at the edges. The mix used was a 1:1½:3. 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. COST STATEMENT--SHERIDAN PAVING--1917 Quantity Item Cost Unit Cost 2498 cu. yds. Common Excavation } 652 cu. yds.

This request was granted by the Highway Commission and in the early spring, construction was started on the additional 2.2 miles. The type of pavement laid on this section was the same as that laid in 1917, except that crushed rock aggregate was used instead of gravel, and the mix was reduced to 1:2:3½.
