Groenier, James Scott. 2020. Sustainable Trail Bridge Design. 2023 2805P. Missoula, MT: U.S. Department of Agriculture, Forest Service, National Technology and Development Program. 66 p.

The Forest Service manages more than 157,000 miles of trails and more than 6,700 trail bridges. Designing trail bridges based on trail-specific TMOs is essential for providing the desired trail experience, for ensuring user safety, and for maximizing bridge longevity. Managing a trail bridge for sustainability requires proper siting, good design details, routine inspections, and maintenance. This report focuses on designing new, short, single-span, wooden trail bridges that the Forest Service classifies as minor and major trail bridges and briefly discusses prefabricated steel bridges.

Keywords: trail bridge design, trail bridge construction, trail bridge inspection, trail bridge maintenance, trail bridge materials, trail bridge plans and specifications, trail bridge siting, trail bridge structure, trail bridge types
