Cathodic protection has become the preferred method for mitigating corrosion of steel reinforcement in concrete in Florida's marine bridge substructures. Over the past twenty years, the Florida Department of Transportation (FDOT) has installed a variety of cathodic protection
systems including both impressed current systems and sacrificial anode systems. An overview of the installation and long term performance is presented for cathodic protection systems comprised of: 1) conductive rubber anodes, 2) titanium mesh anodes cast into structural concrete,
3) titanium mesh anodes cast into grouted pile jackets, 4) sacrificial zinc mesh anodes cast into grouted pile jackets and, 5) sprayed zinc anodes. Additionally, an overview is presented on FDOT experience with the use of remote monitoring systems and alternate power supplies such
as solar power and battery power.
