The Florida Department of Transportation has used impressed current cathodic protection on bridge substructures for over 20 years. Several types of these systems have been evaluated and some have been modified to better meet the needs of the structures. This paper describes the most utilized applications and the long term performance, maintenance, and installation costs associated with the successful operation of the systems. The presented applications use titanium mesh anodes installed in various configurations to meet the cathodic protection requirements and conform the structures' geometry. It also describes the experiences using conductive rubber and polymer cable anodes installed for corrosion control of bridge pilings.
