These detailed engineering drawings depict the Lower Cibola Bridge replacement project, located in Imperial County, California and La Paz County, Arizona. The comprehensive set of technical plans includes multiple sheets with detailed structural specifications for bridge superstructure, abutments, beams, pile bents, guardrails, deck configurations, and transition details. The drawings cover various technical aspects such as prestressed concrete beam designs, steel beam configurations, typical section views, elevation plans, and specific construction details for bridge components including bearings, joints, and reinforcement requirements. The plans are prepared for the Colorado River Front Work and Levee System, with multiple cross-sections and technical annotations indicating precise engineering specifications for bridge reconstruction or modification.
