Sundt-Cannon Rebuilds $111M Interchange in Gem State
The joint venture of Sundt-Cannon recently began pile driving operations for new bridges on the I-86/I-15 System Interchange project in the Pocatello/Chubbuck metropolitan area of Idaho, a significant milestone on the massive $111 million project.
Construction crews are making solid progress on the I86/I-15 System Interchange project in the Pocatello/Chubbuck metropolitan area of Idaho. The joint venture of Sundt-Cannon is serving as the general contractor on the project. Crews recently began pile driving piers for the new bridges, a significant milestone on the massive $111 million project, in the beginning of November. The old interchange was built in the mid-1960s and the aging and obsolete bridges need to be replaced. In addition,
Pocatello and Chubbuck have grown significantly to the north of I-86 and east of I-15, resulting in more congestion on the interchange. “The aging bridges will continue to get closer and closer to the end of their design lifespan,” said Project Co-manager Greg Roberts, “They would still be functional, but weight limits would start to have to be imposed on truck traffic. That would negatively impact Pocatello’s economic future.” The Chubbuck Road overpass has been closed since August. The project consists of the removal of the existing
bridge, excavating new embankments and creating bridges for I-15 to pass over Chubbuck Road. The final Chubbuck Road design will be easier and safer to navigate for motorists, bicyclist and pedestrians. The area west toward Chubbuck from the Pocatello Creek onramp has been a particularly challenging spot for drivers travelling, which was the catalyst for needed improvements. “Drivers have just 2,400 feet to move from the right lane to the far left lane to exit to I-86,” said District Engineer Todd see INTERCHANGE page 6
