POST FALLS, Idaho — Construction at the I-90 and State Highway (SH) 41 Interchange in Post Falls is starting up again on Monday night. This means drivers should expect overnight lane closures on I-90, according to the Idaho Transportation Department (ITD).
Nighttime lane closures on I-90 will begin on Monday. In late March, SH-41 will be closed for several nights while crews work on a temporary bridge over I-90 and. Ultimately, crews will focus on building three permanent bridges for westbound I-90 and three permanent structures for eastbound I-90 this season.
Impacts to traffic are as follows:
- Two lanes will be open during the day with reduced shoulders on I-90.
- The speed limit will be lowered to 55 mph on I-90 and 25 mph on SH-41 and Seltice Way.
- Intermittent lane restrictions on I-90 at night. Nighttime work hours are generally from 8 p.m. to 5 a.m. Work will start at 10 p.m. during special events.
Drivers are asked to pay attention to signage in the work zone for the exact timing of traffic impacts.
“Everything we do is dependent on the weather, particularly in these next few months,” ITD Project Manager Shannon Stein said. “This work zone is complex, with crews planning to work on several areas of the interchange at the same time.”
ITD said bridge construction will be the main focus of the 2023 construction season. Specifically, crews plan to work on a temporary bridge on I-90 over SH-41 to maintain traffic during construction. Crews will also work on three permanent structures for eastbound I-90 and, later in the year, three permanent bridges for westbound I-90.
“Unlike last year though, drivers will see construction shift to other areas of the project, including the Seltice Way/SH-41 intersection and near Central Avenue to work on the future underpass for pedestrians,” Stein said.
