DescriptionThis paper summarizes the field performance of three stress-laminated deck timber bridges located in Wisconsin, New York, and Arizona. The deck superstructures of these single-span highway bridges is comprised of full-span glued laminated timber (glulam) beam laminations manufactured with southern pine, hem fir/red maple combination, and/or Douglas fir lumber species. These bridge structures were evaluated as part of a National Timber Bridge Monitoring Program for 2-3 years following construction. Field data collection for these single-span bridges included moisture content, prestressing force, and static load tests. Based upon these collected field data and comprehensive visual inspections, the bridges have performed satisfactorily with no structural or serviceability deficiencies.
