Idaho Demonstration Project: Replacement of SH 75 East Fork Salmon River Bridges

As a part of the Highways for LIFE initiative, the Federal Highway Administration provided a $1.38 million grant to the Idaho Transportation Department (ITD) to replace two bridges on SH 75 in Custer County. One of the bridge structures crosses over the Salmon River, and the other crosses over the East Fork of the Salmon River, between mile post 226.6 and mile post 227.4. The project’s innovative aspects included the use of precast bridge elements and system (PBES) and accelerated bridge construction (ABC), which enabled completion of construction and opening of the new bridges to traffic in one construction season and provided ITD personnel with valuable experience in this technology. The project was let on January 14, 2014. The construction began in spring 2014 and was completed and open to traffic in fall 2014. The traffic volume on this rural roadway was very small, and because the two bridges were constructed on new alignments, there was minimal impact on the traveling public. The total construction cost incurred by ITD on this project, including mobilization, was $7,367,883. The overall experience of the project was positive, as it enabled completion of two bridges in one construction season with minimal change orders. As a consequence of the experience gained on this project, ITD plans to specify precast abutments and columns where practical in the future.
