The Strategic Highway Research Program 2 (SHRP2) Renewal Area is developing ABC products that help bridge owners upgrade their aging bridges rapidly, with minimum disruption, to last longer, and to do so consistently throughout the nation. A major project to develop such products is R04, “Innovative Bridge Designs for Rapid Renewal.” The presentation focuses on the ABC toolbox that has been developed in this project. The toolbox includes standard plans and details for designs that are as light, simple, and easy as possible to design, fabricate, transport, and erect. Spans range from 40 ft to 140 ft for one-piece installation, and up to 200 ft for multiple pieces to be assembled at the site. The standard plans and details for prefabricated modular abutments, piers, and superstructures are discussed. These modular sections were developed for erection with conventional equipment, including above-deck carriers and launching systems. The presentation also includes a design example using these products.
