The Idaho Transportation Department (ITD) is working with the City of Idaho Falls and Bonneville County to study ways to improve I-15 and US-20 to better serve Idaho Falls and the growing region.
ITD is conducting a PEL study of six interchanges within a two-mile area that have outlived their usefulness and service capacity. Traffic volumes and congestion and aging infrastructure are impacting safety and travel for all users. This study is a necessary and important preliminary step in redesigning the corridor to provide a safe and reliable commute for the next 20 years and beyond.
