Accelerated Bridge Construction Promises Cost-Effective and Less Disruptive Replacement
Typical bridges can be replaced quickly and cost-effectively with accelerated techniques that do not require special equipment. The second Strategic Highway Research Program (SHRP 2) S2-R04-RR-1: Innovative Bridge Designs for Rapid Renewal documents the development of standardized approaches to designing and constructing complete bridge systems for rapid renewals. The report describes a demonstration project on US 6 over the Keg Creek near Council Bluffs, Iowa that was completed in 2011 using the accelerated bridge construction standards developed as part of Renewal Project R04.
ABC for Everyday Bridges highlights the specific techniques used to deliver a new bridge with only a 10-day closure in this Keg Creek bridge replacement project. The design tool kit used in the project was developed through the second Strategic Highway Research Program, a division of the Transportation Research Board.
SHRP 2 Renewal Project R04 also developed an Innovative Designs for Rapid Renewal Toolkit that describes standardized approaches to designing and constructing complete bridge systems for rapid renewals, as well as a case study on the accelerated bridge construction techniques used in the I-84 bridge project in New York. In addition, the project developed a half- and full-day presentations to help facilitate training on of the accelerated bridge process to interested parties.
