POST FALLS, Idaho — Expect some big changes at the Interstate 90 and State Highway 41 early Friday morning in Post Falls.
The Idaho Transportation Department plans to open parts of the new Single Point Urban Interchange that has been under construction since 2022.
State Highway 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 on-ramp and eastbound off-ramp.
Several closures will be in place in the area overnight on Thursday to set up for these changes to go into effect early Friday morning.
From 7 p.m. to 6 a.m. on Thursday, drivers can expect SH-41 to be closed from 12th Avenue to Seltice Way. The I-90 eastbound off-ramp and westbound on-ramp will also be closed.
Additionally, Mullan Avenue will be closed from SH-41 east to October Glory Street. This closure could be in place for several days rather than just overnight.
ITD says there will also be temporary changes to side street and business access along SH-41 between 12th Street and Neufeld Lane while crews lower the ground and add gravel to build temporary road connections.
Drivers should pay close attention to signs and lane markings as they get used to the new layout, especially people driving south on SH-41.
“As we implement these traffic changes, we are asking drivers to please plan extra time and follow the signs and traffic control devices,” Project Manager Randy Durland said. “As drivers adjust to these changes, we appreciate everyone’s patience and extra attention in the work zone for the safety of both drivers and workers.”
