The cathodic protection system on the Yakima River Bridge on SR-24 near Yakima was evaluated for proper operation. Three out of six reference electrodes and rebar probes were found to be non-functioning. One temperature sensing thermistor was also found to be non-functional. All three deck zones were found to be receiving the proper cathodic protection current. Recommendations were made to continue the monitoring at regular intervals and maintain the present rectifier settings.
