42 | ASPIRE , Winter 2011 F H WA F H WA T he purpose of the Highways for LIFE Pilot Program is to advance Longer-lasting highway infrastructure using Innovations to accomplish the Fast construction of Efficient and safe highways and bridges. Innovation is key to finding our way out of the highway challenge. Innovation is an inclusive term used to convey all of the following: technologies, materials, tools, equipment, procedures, specifications, methodologies, and processes or practices used in the financing, design, or construction of highways. The first part of this article was published in the Fall 2010 issue of ASPIRE.™ It provided the background, objectives, project eligibility requirements, and availability of funding for the Highways for LIFE Pilot Program. In this article, the focus is on projects using accelerated bridge construction (ABC) technology and prefabricated bridge elements and systems. The Federal Highway Administration (FHWA) has sponsored workshops on these technologies in 11 states and more are being planned. Demonstration Projects The Highways for LIFE Pilot Program offers incentive funding for states to try innovative approaches. Between 2005 and October 2009, the program awarded approximately $25 million to 25 projects in 21 states, highlighting more than two dozen innovations, such as wider use of ABC techniques and innovative, performance-based contracting. FHWA encourages the states to work in partnership with the private sector to test and evaluate emerging highway technologies to move them closer to commercialization. The program capitalizes on private sector creativity by funding the best ideas already being developed by industry. The objective is for the states to gain valuable experience in using the innovations and be able to champion deployment of the innovations. Documentation is a valuable resource for decision makers and practitioners as they adopt innovation. For each demonstration project, FHWA is producing a summary report on success in meeting performance goals. The reports, which also compare the costs and benefits of using the innovation compared to traditional construction, will guide decision makers as they choose the best solutions for their projects. Information Dissemination Information dissemination is an essential c o m p o n e n t o f t e c h n o l o g y d e p l o y m e n t , both to help transportation stakeholders use innovations effectively and to expand awareness of the Highways for LIFE mission to improve the American driving experience. The initiative uses a full range of communications tools to tell the innovation story, including workshops, showcases, presentations, brochures, handouts, trade shows, DVDs, videos, reports, and articles in industr y publications. The following are examples of completed projects. Iowa DOT Project The Iowa Department of Transportation (IowaDOT), the Nebraska Department of Roads, and FHWA, in coordination with the city of Council Bluffs and the Metropolitan Area Planning Agency, proposed improvements to the interstate system around Council Bluffs, Iowa, with improvements extending across the Missouri River on I-80 into Omaha, Neb. The primary component of this project was to replace the existing four-span 24th Street Bridge over I-29/I-80 with a wider and longer two-span bridge. This project was completed in only one season under an accelerated construction schedule using contract and construction innovations. IowaDOT's approach realized a cost savings of about $1 million or 8% of the total project over conventional construction practices. A significant amount of the cost savings was from reduced construction time. A key feature was the use of full-depth, precast concrete deck panels. Detailed information about this project is provided at http://www.fhwa.dot.gov/ hfl/summary/ia/. Utah DOT Project The 4500 South Bridge on State Route 266 in Salt Lake City, Utah, was built in 1971. The four-span bridge crossed I-215 and served as an important access point for local businesses and residents. The bridge was in very poor condition. The Utah Department of Transportation (UDOT) needed to expedite the removal and replacement of the bridge. After exploring alternatives and evaluating project and user costs, UDOT selected innovative ABC and project delivery strategies. The biggest innovation was the removal and replacement of the bridge using self-propelled The Highways for LIFE Pilot Program by Kathleen Bergeron and Myint Lwin, Federal Highway Administration Seventy full-depth precast, high-performance concrete deck panels, 8 in. thick, 10 ft long, and 52 ft 4 in. wide, were used on the 24th Street Bridge over I-29/I-80 in Council Bluffs, Iowa.
