Abstract:As part of a national initiative sponsored by the Federal Highway Administration under the Highways for LIFE (HfL) program, the Oregon Department of Transportation (ODOT) applied for and was awarded a $1 million grant to showcase and demonstrate the use of alternate project delivery and innovative accelerated bridge construction (ABC) in removing and replacing five bridges on Oregon 38 between the towns of Drain and Elkton. This report documents the entire work, including the use of all the innovative ABC techniques employed by ODOT in rapid removal and replacement of the bridges. Also included in this report are construction details of the bridge superstructures built next to the old bridges on temporary supports over Elk Creek, prefabricated and cast-in-place bridge components, an innovative staged construction technique, the use of a temporary bridge, and the substructures built under the old bridges without interfering with traffic flow. Overall, the innovative features and accelerated elements of the ODOT HfL project included the following: Innovative public outreach program, Design-build method of project delivery, Construction of superstructures next to old bridges, Construction of substructures without interfering with traffic flow, Context-sensitive and sustainable solutions, Rapid bridge replacement technique using a hydraulic sliding system, Use of a temporary bridge, Use of prefabricated bridge components. Removal and replacement of the bridges on OR 38 was a great success and ODOT was able to meet the HfL program requirement related to the project goals of safety, construction congestion, quality, and user satisfaction
