When heavy trucks rumble across the Burlington-Bristol Bridge, new sensors detect the stresses they put on the 2,300-foot span and instantly transmit the information to computers in Philadelphia. Drexel University researchers in the city then use the stream of data to develop computer models that display the bridge's condition and its potential problems. Such measures, known to engineers as structural health monitoring, are commonly done for a limited period and confined to academic research. But Drexel and its partner, the Burlington County Bridge Commission, plan to use the system continuously to help the agency better allocate its resources for bridge maintenance.
