The analysis performed in this study is theoretical and uses data found in the open literature rather than actual data for the bridge. The results presented indicate that the bridge is unlikely to meet a service life of an additional 20 years at reliability levels required by prevailing design codes while foregoing routine maintenance. In the light of the lower than typical reliability predicted by the analysis, more frequent bridge inspections will be needed to maintain safety in the event the bridge is repaired. vii The predictions are critically dependent on assumptions relating to the corrosion rate and statistical distributions …

This report summarizes findings from a 24-month study in which the performance of cathodic protection systems for substructures of two interstate bridges was remotely monitored. The two bridges #860050 and #860054 are located on the “Alligator Alley” toll portion of eastbound I-75 in Broward County, FL. Each bridge spans two pilesupported piers inside a drainage canal. The seven steel H-piles supporting the piers are jacketed in concrete to a level just below the water surface and are cathodically protected by three magnesium anodes spaced uniformly over their submerged length.
