摘要：	As part of a national initiative sponsored by the Federal Highway Administration under the Highways for LIFE program, the Georgia Department of Transportation (GDOT) was awarded a $1 million grant to demonstrate the use of proven, innovative technologies to deliver an $81 million project in less time than conventional construction. This report documents the design-build project in Troup County to construct a new Interstate 85 interchange, 10 miles (16 kilometers) of four-lane frontage and access roadway, another bridge, and all other items associated with this large economic development project. The interchange includes prefabricated bridge substructure elements, used for the first time in the State. This report discusses the use of the design-build (D-B) contracting method, a first for Georgia, implemented under newly passed State legislation. The project also includes other firsts for Georgia, including requiring the D-B contractor to propose state-of-the-art methods to achieve performance expectations, the use of prefabricated elements to construct the bridge substructure and real-time traffic operations support through speed band monitoring on I-85. GDOT also set traffic incident response time goals for this project. Under conventional construction, the impact of this project on the traveling public was estimated at 30 months, but with the use of the D-B contracting technique and prefabricated bridge elements, the impact was reduced to only 16.5 months. / Supplementary Notes: Sponsored by Federal Highway Administration, Washington, DC.
