Bridges on military installations range from multi-lane steel and concrete structures on major roads to single-lane wood timber structures used in remote training areas.  All are critical to the daily operations on the installation.  However, given the age of most of these bridges, corrosion, fatigue, and overload conditions are concerns relative to their continued structural safety.  While inspections are performed biannually, concerns have been raised regarding the ability of standard inspection methods to detect hidden, critical cracking and/or materials degradation in aging bridges.  In addition, these inspection methods may not be effective relative to the use of innovative thermoplastic materials as a substitute for chemical-treated timber in wood timber bridge designs.  This paper will describe the demonstration and validation of state-of-the-art and emerging technologies for the remote structural health and corrosion degradation monitoring of steel and of thermoplastic timber bridges.  Sensors will be used to measure and monitor corrosion degradation, strain, acceleration, acoustic emission, displacement, and temperature on two steel bridges (one in the Midwest and one in the South) and a newly constructed thermoplastic plastic bridge (in the East).  Data will be monitored remotely via wireless communications and a smart data collection and analysis system would be developed and used on the steel bridges.
