Abstract: The Teal River bridge was constructed in late 1989 in Sawyer County, Wisconsin, as part of the demonstration timber bridge program of the U.S. Department of Agriculture Forest Service. The bridge is a stress-laminated deck structure with a 9.91-m length and a 7.23-m width. The design is unique in that it is the first known stress-laminated timber bridge in the United States to be constructed of full-span glued-laminated timber beams rather than the traditionally used sawn lumber laminations. The performance of the bridge was continuously monitored for 2 years, beginning at the time of installation. The performance monitoring involved gathering data relative to the moisture content of the wood deck, the force level of stressing bars, the deck dead load deflection, and the behavior of the bridge under static-load conditions. In addition, comprehensive visual inspections were conducted to assess the overall condition of the structure. On the basis of 2 years of field evaluations, the bridge is performing well with no structural or serviceability deficiencies.
