Innovative Bridge Designs for Rapid Renewal

The nation’s aging bridge inventory, combined with increasing traffic congestion and increasing work-zone safety concerns, requires new approaches to how bridges are designed and built. Typical construct-in-place processes, such as erecting beams, erecting formwork, tying deck reinforcing steel, placing deck concrete, and allowing concrete to cure, are time consuming. On rapid renewal projects, these and other sequential onsite construction activities also disrupt traffic and degrade highway safety. Needed now are approaches to reform these sequential processes into complete bridge systems that come ready for immediate installation at the site, bridges that can be replaced in totality or incrementally with no impact to rush hour traffic, and bridges that can be readily moved to new locations for reuse to address traffic pattern changes and emergency replacements. Innovative construction equipment, such as self-propelled modular transporters (SPMTs), is now available in the United to move such bridge systems. The objective of this project is to develop standardized approaches to designing, constructing, and reusing (including future widening) complete bridge systems that address rapid renewal needs and efficiently integrate modern construction equipment.
