The State Highway Department expended in Columbia County during 1917 and 1918, the sum of $488,302.15, which is the largest amount expended in any one county in the state. With this amount the following work was completed:

2.5miles of bituminous paving.
27.2miles of broken stone macadam.
8.2miles of grading.
11 reinforced concrete bridges.
2 reinforced concrete box culverts.

All of this work is on the Columbia River, and all but the 2.5 miles of paving is between the Clatsop County Line and a point about two miles east of Goble.

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.
