Description 

General Construction Company of Seattle submitted a winning bid of $1,244,545 and began building a new Snake crossing on April 10, 1950. The job was to be completed in 450 days but the outbreak of war in Korea and the steel shortage that followed delayed the opening of the span until January 17, 1952.

The bridge is a combination 770 foot cantilever through truss and 1000 foot Warren deck truss. It rests on 12 piers, 9 of them in the water, the tallest being 113 feet and the foundation of the deepest is 52 feet below the water. The 28 foot roadway is 65 feet above the shipping channel, which has a clearance of 432 feet between piers. Two steel barges used in the construction came from the George Sellars bridge project in Wenatchee and were floated over the top of Rock Island Dam before being towed down the Columbia to the Burbank site.
