Plans, designs, and concepts to build and replace bridges faster.
Innovative Bridge Designs for Rapid Renewal (R04)
Transportation agencies must build or replace thousands of bridges in the coming years while balancing the need to reduce congestion and increase worker and traveler safety. Through programs like FHWA's Every Day Counts, agencies have learned about accelerated bridge construction (ABC) methods and prefabricated bridge elements and systems (PBES) and have mainly applied them on a bridge-by-bridge basis. There has not, to date, been an effort to apply standardized designs widely. A standardized approach could reduce the cost of PBES projects. If this type of construction were to become commonplace for bridges, standard sections and shapes for deck panels, columns, footings, abutments, and approach slabs could be fabricated economically and quickly to make prefabrication an even more appealing option for bridge owners.
The SHRP2 ABC Toolkit has concepts including sample plans, design examples, and specifications which will help bridge owners, designers, and contractors advance ABC projects.
This time-lapse video shows accelerated bridge construction (ABC) techniques being used by a local contractor with standard equipment to replace a three-span bridge on U.S. 6 over the Keg Creek in Pottawattamie County, Iowa.
The SHRP2 ABC Toolkit can be utilized to build or replace typical bridges faster and at a lower cost. The concepts can be incorporated into thousands of small to medium span bridge projects with minimal alterations, resulting in reduced onsite construction time, minimized traffic delay and community disruption, improved work zone safety, and improved quality when compared with conventional construction practices.
