Description:
Oregon DOT owns and maintains a number of iconic bridges along scenic SR 101 designed by renowned bridge engineer Conde McCullough.  Many of these are designated as historic bridges and Oregon DOT has an innovative bridge preservation program to maintain and preserve these historic structures.  Cathodic protection is a key component of this preservation program and it has been used for over 30 years to effectively extend the life of these bridges.  The presentation will discuss the history of these historic bridges and the techniques which are being used to keep them in service for future generations to enjoy.
