These are engineering design drawings for a 135' x 28' T-beam bridge project located at Ghiglione Creek in Denali, Alaska, developed by the United States Department of Commerce Bureau of Public Roads, Region 10 in March 1957. The detailed technical drawings include multiple sheets covering site location plans, topographical surveys, structural steel layouts, radial and half-radial sections, superstructure details, pier bearing details, and typical roadway cross-sections. The bridge is designed with specific engineering specifications, including concrete and reinforcement requirements, with construction completed in 1960. The project documents provide comprehensive engineering specifications for a single-span bridge, including detailed measurements, elevation views, structural components, and quantitative estimates for various construction elements.
