I-84 in Nampa will be detoured overnight Sept. 16-19 for work on Karcher Overpass
Interstate 84 will be closed overnight between the Karcher/Midland and Northside interchanges on Monday, Sept. 16 through Thursday, Sept. 19. The closures will allow crews to safely remove the wooden forms that temporarily supported the new bridge deck this summer.
* Westbound I-84 will be closed for two nights – Sept. 16 and Sept. 17. Each night I-84 will be closed from 10 p.m. to 6 a.m.
* Eastbound I-84 will be closed for two nights – Sept. 18 and Sept. 19. Each night I-84 will be closed from 10 p.m. to 5 a.m.
During the four overnight closures, motorists will exit I-84 at Karcher/Midland or Northside and follow a detour along Karcher Road. Flaggers will direct traffic.
Lane restrictions and flaggers will also be in place on the Northside Boulevard between the ramps each night while crews begin to work on the new bridge.
The new Karcher Overpass is on schedule to re-open later this fall. Reconstruction of the Northside Interchange has begun and will continue through early 2021.
