American Falls: Pocatello Ave / I-86 Business Loop

This project is expected to significantly improve efficiency and safety at the intersection.

The Idaho Transportation Department is designing improvements to the intersection of Pocatello Avenue and the I-86 Business Loop in American Falls. The intersection is located along ID-39, a primary route for trucking and agricultural traffic. It also provides a gateway to the American Falls community.

Project Update

Based on extensive technical work and community input, the Idaho Transportation Department has determined that the new intersection will be a Continuous Green T. The Continuous Green T has been designed to serve both trucks and local traffic. In addition, it allows traffic signals to be installed in the future. Construction is expected to begin in 2025.
