The U.S. Army Corps of Engineers has begun a new project to build out the riverhead of the Columbia River at the foot of Mount Rainier.
The Corps is seeking a $1.6 billion contract to build the new bridge on the upper Columbia River, which runs along the southern slope of Mount Rushmore.
The proposed $1 billion bridge is expected to open in 2021.
The project was announced last month in a report from the Army Corps that was released Tuesday, March 20, 2018.
“This project will allow us to create a better river connection, better navigation, and better access for future generations of Americans,” Acting Army Corps Commissioner Joe McBride said in the report.
“A riverhead that is able to withstand future floods, ice storms, and other challenges will help ensure that the Columbia will remain a navigable and accessible river for generations to come.”
The river will span more than 8 miles, and connect to the Columbia, the Columbia Gorge, the Great Lakes, and the Washington-Oregon border.
The $1 million project will create a 3-mile bridge along the lower Columbia River between the Lower Columbia River in Washington and the Columbia-Oregon Border in Oregon.
The Corps said it will use state funds to build bridges across the river, but said it does not intend to use federal funds.
Construction of the bridge will begin in 2021 and be completed in 2022.
