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.^[1]

The bridge's total length is 1568feet.^[1] When open, the 140feet double-leaf bascule provides 110feet of horizontal clearance for boat traffic. The bascule section is flanked by two 154feet reinforced concrete tied arches, identical to those used in the original Alsea Bay Bridge.^[1] Four Art Deco-style obelisks house mechanical equipment as well as living quarters for the bridge operator.^[1] The total cost of the bridge was $527,000 (equivalent to $ million in).

The bridge was added to the National Register of Historic Places on August 5, 2005.^[2]
