A research project is currently under way on the Confederation Bridge, which links Prince Edward Island to mainland Canada. The purpose of the project is to study the short- and long-term performance of the 12.9 km bridge and develop strategies for operating, maintaining, and upgrading it. Campbell Scientific data loggers are used to monitor ice force, deformation in the bridge structure, thermal stress, traffic load, and vibration. Data is transmitted to Carlton University and the University of Calgary for further analysis.
