Cathodic Protection for Viaduct

B. L. Martin, W A Kovatch

Abstract

It is described how the 3,400-ft long, concrete and steel viaduct, one of Salt Lake City's major arteries, was saved from corrosion by cathodic protection with minimal inconvenience to the public. The reasons for using this method over other conventional options are discussed and include its long term performance and cost savings. The details are summarized of the 2-phase rehabilitation program. Routine testing to monitor the performance of the protection system is described.
