TRB’s second Strategic Highway Research Program (SHRP 2) has released a project brief that provides an overview of SHRP 2 Project R04: Innovative Bridge Designs for Rapid Renewal, which developed standardized approaches to designing and constructing complete bridge systems.
SHRP 2 Project R04 created the SHRP 2 Accelerated Bridge Construction (ABC) Toolkit, which includes recommended design standards and design examples for complete prefabricated bridge systems for routine bridges with span lengths from 40 ft to 130 ft.
The Toolkit also includes recommended specification language for ABC systems for future inclusion in the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design and Construction Specifications.
The ABC design standards developed in this project were used in pilot projects in Iowa, New York, and Vermont.
