The road across this siphon bridge is below the level of the river, a design that results in the river helping to support the bridge. It was built in 1919 by the Manistique Pulp and Paper Co., a subsidiary of the Minneapolis Tribune, to create water power for turbines and grinders. The bridge is 300 feet long and 66 feet wide, with a rate of flow of 650,000 gallons per hour, and the flume is 3,000 feet long, 200 feet wide, and 20 feet deep, with drainage covering 1,400 square miles.
