Diverging Diamond Interchanges (DDI)
The Idaho Transportation Department (ITD) is making plans to reconstruct two US-20 interchanges in Rexburg in the summer of 2024. The interchanges are located at:
- University Boulevard (Exit 332)
- SH-33 (Exit 333)
The interchanges will be rebuilt using the Diverging Diamond Interchange (DDI} design. ITD anticipates closing each interchange, one at a time, during construction. The full closures will allow crews to construct the interchanges much faster and complete both interchanges in one construction season.

In the summer of 2024, construction will occur on two US-20 interchanges (Exits 332 & 333) in Rexburg! ITD is working to finalize construction plans and will host a meeting in the spring for the public to learn more about construction plans and anticipated impacts. Prepare for the new interchange design by visiting itdprojects.idaho.gov/pages/us20rexburg to see visualizations about how to drive a DDI.
ITD plans to build one interchange at a time so that both exits are not impacted at the same time. Each interchange is estimated to take 6 weeks of construction time.
