The Idaho Transportation Department advises motorists of an upcoming closure of the eastbound off-ramp on Interstate 90 at Cataldo scheduled to begin Monday. The closure is part of the ongoing bridge replacement project and is expected to last at least three weeks, depending on weather and construction progress.
During this time, eastbound drivers will not be able to exit at Cataldo. Travelers should use the Kingston Exit and return on I-90 westbound to access Cataldo.
The closure will allow crews to remove a temporary ramp and repave portions of I-90 and the existing ramp area needed to shift both lanes of eastbound traffic onto the new bridge for winter.
“We need a short window of decent weather to pave and stripe before winter conditions set in,” Project Manager Megan Koski said. “Our goal is to open the new eastbound bridge to traffic before Thanksgiving, but that will largely depend on how the weather cooperates.”
Because the eastbound off-ramp is part of the detour route for the adjacent Canyon Road Bridge replacement by the East Side Highway District, drivers in the area should expect an updated detour and follow locally posted signs. Questions specifically regarding the Canyon Road Bridge replacement should be directed to the East Side Highway District.
This closure is necessary to ensure safe travel through the work zone during the upcoming winter season. ITD appreciates the public’s patience, and safe driving, as crews complete this important milestone.
Depending on winter conditions, there may be work that is able to be accomplished through the snowy months that will set the stage for the next phase of construction. Drivers may expect to see short duration work zones set up through the area, including the possibility for intermittent single lane closures. Next spring large-scale work will begin to repeat the process of demolition and replacement of the westbound bridge to complete this project.
