Modernizing Critical Interchanges for a Robust Transportation Network
The reconstruction of the I-86/I-15 system interchange in Pocatello, Idaho, is a monumental infrastructure project aimed at significantly improving connectivity and traffic flow. Managed by Tim Morgan, this project began in June 2022 and is expected to continue into 2025.
Atlas is providing inspection and leading all materials sampling and testing for the Idaho Transportation Department (ITD). This complex project involves substantial quantities of engineered fill and sub-base, alongside the construction of eight interstate bridges. Some staggering figures from the project include 4,374,794 pounds of steel bridge components, equating to nearly three miles of individual steel plate girders, and 4,408 linear feet of prestressed concrete girders.
The project demands 9,179 feet of steel pile, 286,888 cubic yards of granular borrow, 898,164 cubic yards of excavation, 227,888 tons of ¾” aggregate base, and 109,531 tons of hot mix asphalt (HMA).
Through meticulous planning and execution, Atlas ensures all quality assurance testing is completed to meet the minimum testing requirements of ITD. This project not only represents a significant improvement in regional infrastructure but also underscores Atlas’ commitment to excellence in engineering and construction.
