I-90 ramp closure near Cataldo to cause multi-week detour

CATALDO — The Interstate 90 eastbound off-ramp at Cataldo will be closed for at least three weeks beginning today as part of the ongoing bridge replacement project, the Idaho Transportation Department announced.

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.”

During this time, eastbound drivers will not be able to exit at Cataldo and will need to use the Kingston exit to use I-90 westbound to access Cataldo.
