The U.S. Army Corps of Engineers Thursday moved forward on the project to deepen the lower Columbia River shipping channel by three feet.
The Corps awarded an $8,738,500 contract to Illinois-based Great Lake Dredge and Dock Co. to maintain the 103.5-mile-long, 40-foot-deep Columbia River federal navigation channel between the mouth and Vancouver, Wash., as well as the six-mile-long channel across the Columbia River bar.
