Multnomah County Line-Scappoose Paving

A contract was awarded to the Warren Construction Company, August 22,

1917, for 2.5 miles of bitulithic pavement sixteen feet wide on crushed

rock base, with two foot macadam shoulders. The old road bed on this

section was in excellent condition for base for pavement being old

macadam about sixteen feet in width. The grade was followed closely,

scarified, and clean crushed rock spread over the entire surface and

rolled. Material was borrowed along each side to obtain the required

twenty-four foot of roadbed.

A sixteen foot span wooden bridge was replaced by an 8x10 feet

reinforced concrete culvert built by Lindstrom Bros. on the basis of

cost plus ten per cent.
