Siuslaw River Bridge Cathodic Protection

Overview 



 

The Siuslaw River Drawbridge, at the south end of Florence on U.S. 101 in Lane County,  is scheduled for rehabilitation work.  A cathodic protection system and structural repairs are needed to protect the bridge from deterioration due to age and the harsh coastal environment; these repairs will allow the structure to remain in service for many years to come.
 
 
 
 
ODOT Engineers are currently designing plans to repair damaged concrete, replace bridge railings and construct sidewalk features at the bridge ends.  One major component of the project is to install cathodic protection that includes a zinc surface coating to protect the structure from corrosion.

 

 

History 



The Siuslaw River Drawbridge was first opened to traffic in 1936, it is one of Oregon’s original historic coastal bridges designed in the Art Deco style by Oregon’s renowned state bridge engineer, Conde McCullough and is listed on the National Register of Historic Places.  The bridge cost $527,000 to construct. The federal Public Works Administration provided funding.
 
 
 
 
 
 

The Florence bridge was one of five major structures built as part of Oregon’s Coast Bridges Project. Like the other bridges completed on the Oregon Coast Highway in 1936, the Siuslaw River Bridge replaced ferry service across one of Oregon’s major rivers. The bridge was built by the Mercer-Fraser Company, Eureka, California.

 

 

Construction   

 

The project will be bid in 2015 and construction is expected to take three years.  Temporary work bridges are needed for construction and will be erected alongside the structure except in the center navigable water channel which will be kept open to accommodate boat traffic. Impact to traffic on the bridge will be minor.
