The total cost of the structure complete will be about $48,000.00, of which Hood River County will contribute $8,000.00. The bridge was built under contract by Parker & Banfield. Mr. C. E. Carter was resident engineer on the work.
Herman Creek Bridge
This is a ninety-foot reinforced concrete viaduct on the Columbia River Highway near Cascade Locks. This structure was built by A. D. Kern in connection with the grading contract on the Cascade Locks section. The cost complete was $7,389.06.
Gorton Creek Bridge
This is a 50-foot reinforced concrete bridge at Wyeth on the Columbia River Highway. It was built by A. D. Kern under the grading contract for the Cascade Locks Section. The total cost was $3,153.90.
Hood River-Mosier Surveys
Contemplating construction of the Columbia River Highway between Hood River and Mosier to eliminate the high summit, narrow road bed, and excessive grades between these points the Department made very thorough surveys for this important project.
A survey had previously been made developing distance up the Hood River Valley and reaching a summit of 1,107 feet with a corresponding additional length required on the Mosier end, making a total distance of 10.7 miles.
Because of its length and high summit a lower route was considered and a survey was made adjacent to the railroad, using a portion of the old abandoned railroad grade, but involving extremely heavy construction at certain points where the line skirts the high bluffs. The summit on this route was only 160 feet and its length 5.8 miles. However, the railroad company was contemplating a revision in the alignment of their tracks on this section, as well as the construction of a second track, which would still further lessen the space available for a highway. Also taking into consideration the difficult nature of the work and the uncertain cost due to track protection in blasting operations and the limited conditions under which the work must lie done to avoid interference with the railroad traffic, this route was revised in favor of a route further away from the tracks up on the side-hill. The summit reached is 522 feet and the length of this line is 6.3 miles, which includes a development of 5 per cent grade at each end and provides for a 24 foot roadbed.
This adopted route is very scenic and affords a splendid view of the Washington shore, as well as a view up and down the river. The construction is very heavy, being located on steep side-hill slopes and at one point involves a tunnel 200 feet long. This project is divided by the County line, making 4.0 miles in Hood River County and 2.2 miles in Wasco County. This project will be placed upon the 1919 program.
