Wooden bridges, such as historic covered bridges or modern railroad and highway bridges, can become susceptible to subterranean termite feeding. This can result in weakened structural integrity of the wooden members of these bridges, and possibly even structural failure if damage is not discovered early and control measures are not implemented. The goal of this study was to evaluate the use of various remote detection methods, including acoustic emission sound waves, interruption of light transmission, radar and microwave transmission, moisture monitoring, and changes in gas concentrations in detecting termite activity. Successful methods for remote termite detection would reduce the number of annual site visits required to assess these structures and provide an early warning for potential damage, which could significantly reduce repair costs.
