About this project
US-20 is the main transportation corridor for Rexburg and much of northeast Idaho. As the area continues to grow, delays at two interchanges (US-20/University and US-20/SH-33) are expected to reach unacceptable levels.
ITD has been working with the city of Rexburg, Madison County and BYU Idaho to evaluate and design possible improvements for both interchanges.
