Interstate 86, Chubbuck Interchange to Pocatello Creek Interchange

Fast Facts

Location: Interstate 86 / I-15, Pocatello
Cost: $8.1 Million
bullet Jobs Created / Sustained: 145

Why it Matters

Traffic volume on major routes in the Pocatello urban area continues to grow, resulting in considerable congestion during morning and evening commutes. The need for a significant improvement was first identified in 1998 as part of an overall Urban Interstate system study. It was confirmed in a subsequent 2003 Yellowstone Avenue corridor plan.

Yellowstone, Alameda, I-86 and I-15 serve as primary routes for traffic within the urban boundaries of Pocatello, with each carrying about 30,000 vehicles daily. Existing conditions at the morning an evening commutes within the project area are of level of service F on surface streets and level C on the interstate. Construction of auxiliary lanes will elevate the level of service and vastly improve commuting for area motorists.

Project Description

This project consisted of adding an auxiliary lane on Yellowstone, between Lou Avenue and the Chubbuck Interchange. At that point, the additional lane will continue along the eastbound on-ramp, then along I-86 to the Wye Interchange with I-15 and continue south on I-15 to the Pocatello Creek interchange. It will progress along the southbound off-ramp onto Alameda Road and continue west to Jefferson Street.
