POST FALLS, Idaho — Drivers can expect some big changes at the I-90 and State Highway 41 Interchange in Post Falls early Friday morning.

The Idaho Transportation Department (ITD) announced on Wednesday that it plans to open portions of the new Single Point Urban Interchange (SPUI), which has been under construction since 2022.

ITD says for the first time, SH-41 traffic will be shifted to the west to run underneath the new bridges and connect to the heart of the SPUI. Drivers will also be able to use the new westbound I-90 on-ramp and eastbound off-ramp.

ITD notes that making the shift will require several large-scale closures throughout the interchange area overnight on Thursday to set up cones, barriers, and signs that will safely route vehicles through the new traffic pattern.
