Note
The Siuslaw River Bridge is a bascule bridge that spans the Siuslaw River on U.S. Route 101 in Florence, Oregon. It was designed by Conde McCullough, built by the Mercer-Fraser Company of Eureka, California, and funded by the Federal Emergency Administration of Public Works (later renamed the Public Works Administration). It opened in 1936. The bridge's total length is 1,568 feet (478 m). When open, the 140-foot (43 m) double-leaf bascule provides 110 feet (34 m) of horizontal clearance for boat traffic. The bascule section is flanked by two 154-foot (47 m) reinforced concrete tied arches, identical to those used in the original Alsea Bay Bridge. Four Art Deco-style obelisks house mechanical equipment as well as living quarters for the bridge operator. The total cost of the bridge was $527,000.
