Title Data Processing and Control System to Support Remote Infrastructure Monitoring.

Abstract The Hurley Bridge (Wisconsin Structure B-26-7) carries westbound traffic on US Route 2 over the Montreal River from Ironwood, Michigan to Hurley, Wisconsin. The bridge is a three-span continuous five-girder steel structure with a composite deck. In cooperation with WisDOT, the Research Engineering Group (REG) of ITI has installed a continuous remote structure health monitoring system on the bridge consisting of strain gauges, thermocouples, accelerometers and displacement transducers at selected locations, in conjunction with a weigh-in-motion system installed by a third-party contractor. The bridge is subject to heavy loads from daily truck traffic, many of which are believed to be overweight logging trucks travelling from Michigan into Wisconsin. WisDOT is concerned about that the observed traffic will cause premature degradation of the structure due to fatigue and overstress conditions.
