The Infrastructure Technology Institute (ITI) at Northwestern University has installed what is believed to be the first continuous remote monitoring system on a highway bridge in the world. The system was installed on a rolling bascule bridge over Sturgeon Bay in Door County, Wisconsin. It allows engineers located at ITI to closely monitor crack propagation and other conditions on the bridge which is near the end of its design life. The system is intended to serve as the prototype for a new method to monitor the condition of aging bridges in order to ensure public safety and allocate scarce rehabilitation and replacement funds in an optimal manner.
