These are engineering design documents for the Gilead Bridge Redesign project, located in the White Mountain National Forest in Oxford County, Maine, prepared by the USDA Forest Service's Eastern Region (R9). The project involves redesigning an existing bridge, with detailed technical specifications for a steel bridge featuring W24 x 68 steel girder beams, a 12-foot clear width, 4-inch laminated deck panels, and a complete railing system. The design includes specific construction requirements such as using AASHTO M270 Grade 50 steel, treated lumber, and precise attachment methods for deck panels, backing boards, and structural components. Technical details specify a 61.3-foot span, 60.3-foot bridge length, and 12-foot width, with additional specifications for foundation, abutment modifications, signage, and bridge identification placard installation.
