Erosion triggers most bridge collapses, so a Pitt engineer buried an alarm
Michael Rothfuss buried 15 PVC tubes packed with batteries and radios around a remote bridge that spans a small creek in Armstrong County more than two years ago.
He hasn't heard from them since.
Rothfuss, who has a Ph.D. in electrical engineering from the University of Pittsburgh, placed the tubes as part of a Pitt RFID Center of Excellence project. It was to help PennDOT improve erosion monitoring around underwater support structures of remote, rural bridges.
