The Sam Hill Memorial Bridge carries U.S. Highway 97 over the Columbia River between Maryhill, Washington, and Biggs Junction, Oregon. The steel truss bridge is 2,567 feet long with a 341-foot main truss span and a vertical clearance of 75 feet above the river. Construction began on October 3, 1960 and it was built at a cost of $2.4 million. During its opening ceremonies on November 1, 1962, it was dedicated to Sam Hill, early bridge proponent and builder of the Maryhill Museum of Art. Initially the Washington State Bridge Toll Authority charged a toll of $1 per car, until the toll was removed in February 1975.
