Significance: The bridge is significant as the only means of pedestrian and vehicular access across the Middle Channel of the Spokane River to the Middle Channel Island, which is the site of the power plant and Middle Channel dam. The reinforced concrete structure is 221' long, and it consists of 13 spans: the eastern approach contains 3 spans, the arch 8 spans, and the western approach contains 2 spans. The bridge is basically unaltered from the time of its construction in 1929.
