The document is a set of detailed technical design drawings for a glued-laminated stringer trail bridge (Bridge #24-14.0) located in the Horseshoe Creek area of the Custer Gallatin National Forest's Beartooth Ranger District. The comprehensive 5-sheet design package includes project design criteria, isometric and plan views, deck and stringer details, connection specifics, and foundation alternatives using geocell or gabion foundation methods.

Key technical specifications include a 49'-0" span length, 36" overall width, glutam Douglas fir wood type for stringers, port orford cedar for running planks and decking, and designed to support an 85 psf pedestrian/equipment live load and 200 psf ground snow load. The bridge is configured with 5 glued-laminated stringers, no handrails, and will utilize two geocell or gabion foundation types at the abutments. The design is standardized for the Northern and Northwest Regions of the U.S. Forest Service, with detailed provisions for timber treatment, hardware specifications, and construction methodologies.
