On the cathodic protection system for concrete structure, a galvanic anode system is recently highlighted as maintenance-free system. But, only some reports on the periodic or continuous monitoring of its performance can be found. The report covers the continuous monitoring of the performance on our galvanic anode system with “aluminum panel anodes”, applied to the concrete highway bridge. The external view on the bridge was kept in initial condition for eight months after application. Although more positive ON potential of the rebar and lower output current of anode per unit rebar surface area were observed at lower ambient temperature, the rebar potential was kept in sufficient protection level.
