Prefabricated Bridge Elements and Systems"Get in, get out, stay out." Why Use?Prefabricated bridge elements and systems may be manufactured on-site or off-site, under controlled conditions, and brought to the job location ready to install. Using prefabricated bridge elements and systems facilitates meeting key public needs:
Traffic and environmental impacts are reduced, constructibility is increased, and safety is improved because work is moved out of the right-of-way to a remote site, minimizing the need for lane closures, detours, and use of narrow lanes. Prefabrication of bridge elements and systems can be accomplished in a controlled environment without concern for job-site limitations, which increases quality and can lower costs. Prefabricated bridge elements especially tend to reduce costs where use of sophisticated techniques would be needed for cast-in-place, such as in long water crossings or higher structures, like multi-level interchanges. Prefabricated bridge elements and systems is one of FHWA's Priorities, Market-Ready Technologies and Innovations.
