Drill crews will gather soil samples near the junction of I-90 and ID-41 in Post Falls through the month of October to gather data for the interchange’s redesign.
Sample collection will affect drivers next week (Sept. 30) as crews start working nights.
Nighttime work between 7:30 p.m. and 5:30 a.m. will require single-lane closures on the highway and Seltice Avenue for one week. Drills will then move to the interstate, with one to three weeks of nighttime, single-lane closures possible.
No work will take place on weekends, and on- and off-ramps will remain at least partially open.
The interchange is planned to start construction in 2023, with another opportunity for public comment scheduled for this winter. To learn more about the new design for the interchange, visit itdprojects.org/id41corridor.
