From Washington, D.C. to Washington State; the second megaproject on our list takes us to the other side of the country. The Washington State Department of Transportation (WSDOT) is seeking bidders to demolish and rebuild the bridge that carries I-5 traffic through Brush Prairie. The reason “Multiple Locations” is in the project name is because this is part of the greater Columbia River Bridge Replacement Project, which also includes bridge sections across the state border into Portland, Oregon. This specific project up for bid, is only concerning the section in Brush Prairie, Washington.
Bids are due August 19, with work expected to begin four months later, on October 19.
