These engineering design drawings detail the Gibbon River Bridge replacement project located in Yellowstone National Park, Wyoming, as part of the Grand Loop Road infrastructure improvements. The comprehensive set of technical drawings, prepared by the U.S. Department of Transportation's Federal Highway Administration in April 1996, provides detailed structural specifications for a bridge rehabilitation project, including precise plans for wingwalls (A, B, and C), rail systems, footing plans, excavation limits, masonry details, and reinforcement requirements.

The drawings specify intricate construction elements such as concrete structural specifications, reinforcing steel configurations, anchor and dovetail details, rail post assemblies, and precise dimensional measurements for various bridge components. Key technical specifications include structural concrete class requirements, reinforcement steel grades, live load considerations, and specific detailing for elements like rail caps, splice details, and masonry anchor configurations. The documentation provides a comprehensive engineering blueprint for reconstructing the Gibbon River Bridge, ensuring precise structural integrity and adherence to federal transportation infrastructure standards.
