U.S. 101- Big Creek Bridge Cathodic Protection


Big Creek Bridge is located on U.S. 101 between Florence and Yachats at milepost 175.02.
This project will construct a new cathodic protection system to protect the bridge from the harsh coastal environment and extend its useful life.



Big Creek Bridge is one of Oregon’s original coastal bridges built in 193l and designed by renowned ODOT bridge designer Conde McCullough.  It was constructed by Union Bridge Company.  It is listed on the Historic Register.
The Big Creek Bridge is one of the first reinforced concrete tied arch spans to be constructed in this country.  It is very similar in design to the Tenmile Creek Bridge and Wilson River Bridge.
Big Creek Bridge was rehabilitated in 1996 when ODOT altered the entry portals, added a traffic rail, and constructed the original cathodic protection system.



The concrete surface of the structure will be sprayed with a sacrificial carbon based coating so that the steel reinforcements do not corrode.  The cathodic protection system consists of the carbon based coating and an electrical system on a low voltage impressed current.
A containment structure will be constructed around the bridge to facilitate the coating application and eliminate any environmental concerns.
