The bridge's total length is 1,568 feet (478 m).[3] 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.[3] Four Art Deco-style obelisks house mechanical equipment as well as living quarters for the bridge operator.[3] The total cost of the bridge was $527,000 (equivalent to $9.8 million in 2019[4]).
