10 Year Review of Monitoring System on I-35W Saint Anthony Falls Bridge

Principal Investigator:

Lauren Linderman, Assistant Professor, Civil, Environmental and Geo-Engineering


  • Carol Shield, Professor, Civil, Environmental and Geo-Engineering

Project Summary:

The monitoring system for the I-35W bridge has been collecting data since the bridge's opening in 2008. Over 500 sensors were deployed on the bridge, including vibrating wire strain gauges, fiber optic strain sensors, thermistors, linear potentiometers, corrosion sensors, and accelerometers. The ten-year anniversary of the monitoring system is an appropriate moment to review the time-dependent bridge displacements, monitoring system performance, and sensor viability, and to provide insight on how monitoring systems might be used effectively in the future in Minnesota.
