Six bridges in Indiana were evaluated in terms of traffic, environmental and salt exposure conditions in order to assess the in-service condition of concrete bridge decks reinforced with epoxy-coated steel. In all the bridges, no signs of steel corrosion were found in the bar samples extracted from the cores. The chloride concentration levels at the level of the reinforcement for all but two of the bridges were well above the commonly accepted threshold value at the level of the reinforcement. Evaluation of the field data to data revealed that the combinations of adequate concrete cover and epoxy coating provided a good corrosion protection system in Indiana.
