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 bascule section is flanked by two Script error: No such module "convert". 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.

The bridge was added to the National Register of Historic Places on August 5, 2005.[2]
A new computerized control mechanism for the drawbridge was installed in 2011. It does not require an operator to be present at both the north and south portions to raise the drawbridge like the manual controls do. However, the manual system is still in working order.[1][3]
