SENSORS DESIGNED TO PROTECT FAMOUS COVERED BRIDGES

Researchers at Iowa State University’s Bridge Engineering Center have been working cooperatively with the U.S. Department of Agriculture Forest Service’s Forest Products Laboratory in the design and installation of a three-component wireless monitoring device at one of the five remaining historic wooden bridges in Madison County, Iowa. This surveillance system, which is comprised of infrared, fiber-optic, and flame detection components, is connected with the local Iowan electrical grid to be monitored by the Madison fire department. Although the bridges are predominately ornamental, their cultural value warrants the most technologically advanced surveillance, in part because traditional, less expensive, methods prove less useful in rural outdoor areas. Since 2002, two arson attacks have destroyed one of the century-old bridges and damaged a second. Therefore, the location of the specific bridge that is being outfitted with the surveillance equipment is not being disclosed. In order to prevent tampering with the devices, the equipment, along with the power supply, they have been camouflaged in the nearby landscape.
