Ralph L. Wadsworth is excited to work with the Idaho Transportation Department on yet another challenging project. The project site is located on I-84 over the Snake River just east of Burley, Idaho. The primary scope of the project consists of the demolition and replacement of two existing bridges, each spanning approximately 1,000’. These bridges are an integral part of both intrastate and interstate transportation, connecting numerous major cities throughout the region.
The original structures were built in 1960 and reconstructed 16 years later; Ralph L. Wadsworth will demolish and replace these aging structures with two new bridges continuing along the existing roadway alignment. Not only will the structures be replaced, but the aesthetics of the structures will be greatly improved as well, reducing the number of spans per structure from over twenty to only five. This will afford recreationists on the Snake River a much less obstructed view of the area.
Progress began in the spring of 2015, and as of late September the structure servicing the westbound lanes of I-84 has been completely demolished, with both eastbound and westbound traffic traveling on the eastbound bridge. A temporary work bridge has also been constructed across the majority of the river, affording crews and equipment safe access to work locations. As of October 2015, crews have begun preparing and drilling the foundations for the structure, some as deep as 40’ below the water’s surface.
