Two weeks? That really is accelerated bridge construction

Greetings!
Bridge designs developed in a SHRP 2 Renewal project are taking shape over the Keg Creek in Iowa this week and next. The designs combine several innovations into standardized approaches that can be easily adjusted to meet the requirements for nearly any bridge project, making the benefits of rapid renewal, economies of scale in manufacturing and construction, reduced traffic disruption, and increased safety widely available.
To demonstrate the design using accelerated bridge construction (ABC) techniques, SHRP 2 is working with Iowa DOT to replace a three-span 210 ft x 47 ft bridge steel/precast modular structure with precast bridge approaches on US 6. Using traditional construction methods would require road closures for several months, but using the SHRP 2 design with ABC techniques will limit the road closure to only two weeks. The Iowa DOT is hosting a project website that provides more information, including a live web camera of the construction, photos, videos, plan drawings, and technical information. SHRP 2 is also producing a documentary video to promote the innovations being demonstrated on this project.
