The concrete was mixed with a sixteen cubic foot Koehring Mixer equipped with bucket and boom. The plant is owned by the Department.
The grading was paid for by Yamhill County and the crusher, roller, grader, and scarifier were also furnished by them free of charge. Earth shoulders were built along the pavement by means of road grader.
Mr. J. M. Baker was Superintendent of Construction on this work.

Paving--Multnomah County Line to Newberg
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.
Survey--Grande Ronde Section
A survey was made in the spring of 1918 between Grande Ronde and the Bee Ranch at the east end of the Sour Gra.s.s road improved in 1916. This is an important link about 6 miles in length on the Yamhill-Nestucca Highway, connecting as it does the cities of McMinnville, Willamina, Sheridan and Tillamook. In addition it will afford a short and direct route between the hay and grain fields of the Willamette Valley and the dairy ranches of the coast. Further, this highway is used by hundreds of autoists in summer enroute to the Tillamook beaches.
From the fact that only 2 miles of this section are in service as a postal route, Federal Aid could be applied for only on that section and cooperation has been requested as follows: United States Government $15,000; State of Oregon $15,000; Yamhill County $10,000. For the remaining four miles, Yamhill County has appropriated $5,000 from the 1919 funds.
It is estimated that the total cost of the remaining section will be $50,000 and it is expected that the work will be done in 1919. The entire project as proposed will be graded 24 feet wide, conforming to the State standards as to alignment and grade and surfaced with macadam 12 feet in width, thus closing the gap and affording a road between Portland and Tillamook which will be open the entire year.
