A tied-arch bridge is an arch bridge in which the outward-directed horizontal forces of the arch(es) are borne as tension by a chord tying the arch ends rather than by the ground or the bridge foundations. This strengthened chord may be the deck ...

. It was designed by Conde McCullough
Conde Balcom McCullough (May 30, 1887 – May 6, 1946) was an American civil engineer who is primarily known for designing many of Oregon's coastal bridges on U.S. Route 101. The native of South Dakota worked for the Oregon Department of Tra ...
and opened in 1931.
The bridge has a total length of and contains one reinforced concrete tied arch, identical in design to Ten Mile Creek Bridge and Wilson River Bridge. The locations for all three bridges were similar in that the sandy foundations were not secure enough for the abutment piers required to relieve the lateral pressure of traditional arches. The flood levels of the rivers approached the road grade and ruled out the use of reinforced concrete girders. The corrosive salt air eliminated the practicality of steel truss bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements, typically straight, may be stressed from tension, compression, or ...
s. The design of the bridge was similar to the rainbow arch design patented by James Barney Marsh.
The bridge, along with the Ten Mile Creek Bridge and the Wilson River Bridge, was rehabilitated in 1996 to increase the overhead clearance and add a cathodic protection
Cathodic protection (CP; ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded " sacrifi ...
system to protect the embedded steel reinforcement against the corrosive air. A project to replace the cathodic protection system began in February 2014.
