| Abstract | As part of a national initiative sponsored by the Federal Highway Administration under the Highways for LIFE program, the Wisconsin Department of Transportation (WisDOT) was awarded a $1 million grant to demonstrate the use of proven, innovative technologies to deliver a $12.5 million project in less time than conventional construction. This report discusses the use of multiple temporary bypass bridges to facilitate the reconstruction of a series of existing bridges. Through the use of bypass bridges to keep traffic flowing at minimal delay and at greater worker and public safety than traditional construction methods, this project surpassed the Highways for LIFE goals of fast, safe, and efficient reconstruction of structurally deficient bridges in an environmentally sensitive wetland. The bypasses enhanced the durability of the finished bridges by allowing for monolithic deck construction, which eliminated the longitudinal deck joint associated with traditional staged construction methods. This project also included innovations such as open pile bents, high performance concrete (HPC), precast bridge elements, and specially designed approach aprons, all of which added to the quality of the bridges. The construction time was reduced by 45 percent compared to traditional staged construction. In addition, an estimated $3.6 million was saved in the total costs of construction, user delay, and safety costs, with the bulk of the savings attributed to minimizing delay costs. In other words, the innovations used in this project had a 29 percent cost benefit over traditional methods. While not meeting every HfL goal, the innovations demonstrated on the project are a step forward for WisDOT in terms of implementing future bridge projects where multiple temporary bypass bridges can by utilized to increase safety, increase quality, and save time and money |
