A number of efforts had been sought to instrument bridges for the purpose of structural monitoring and assessment. The
outcome of these efforts, as gauged by advances in the understanding of the definition of structural damage and their role
in sensor selection as well as in the design of cost and data-effective monitoring systems, has itself been difficult to
assess. The authors' experience with the design, calibration, and operation of a monitoring system for the Kishwaukee
Bridge in Illinois has provided several lessons that bear upon these concerns. The systems have performed well in
providing a continuous, low-cost monitoring platform for bridge engineers with immediate relevant information.
Experiences learned from the design and installation of health monitoring systems for several major long span bridges in
Japan and China will be addressed.
