Gorge Powerhouse sent the first electric power from the Skagit Hydroproject to Seattle in 1924. The rushing water underneath the powerhouse has produced up to 170 megawatts of power, enough to light almost 9,000 homes. A bridge to the left was built in 1935 to accommodate Gorge Powerhouse service vehicles after first serving as a railroad bridge that carried construction equipment and materials to the powerhouse. A small suspension bridge to the right was originally built in 1920 to give construction workers access to the powerhouse site, and it has been rebuilt twice, most recently in 1953.
