Columbia River Channel Deepening

After nearly 20 years of study, planning, litigation, and construction, the Columbia River channel improvement project was completed. The final portion of the 110 mile lower Columbia River navigation channel was deepened to 43 feet deep in November 2010. The Pacific Northwest and the nation are already reaping the benefits with over $900 million in new investment to date. This final increment of funding from the American Recovery and Reinvestment Act of 2009 (ARRA) allowed the U.S. Army Corps of Engineers to remove one mile of rock near St. Helens and complete all of the other work necessary to provide a 43-foot navigation channel from the Mouth of the Columbia River to the Ports of Portland and Vancouver. This channel provides over 40,000 local jobs and supports over 40 million tons of cargo each year; valued at $20 billion in 2009.
