All work associated with removal of the first of four hydroelectric dams slated for demolition on the Klamath River in California and Oregon has been completed by contractor Kiewit, said dam owner Klamath River Renewal Corp. earlier this month.
The project is planned to include design and construction of a 2,625-ft-long, eight-lane immersed tube tunnel to replace the aging four-lane George Massey Tunnel.
