NAMPA, Idaho — A traffic alert for motorists in Canyon County that will last until December.
The Idaho Transportation Department announced a series of closures on Interstate 84 in Nampa beginning next week.
The Karcher Road overpass will be closed for nine months starting on Tuesday, March 12.
ITD is replacing the overpass, which was built in 1966, to clear the way for widening I-84 in Canyon County. The interstate widening is expected to begin this summer and take several years.
The new overpass will include one lane in each direction, wider shoulders and a sidewalk on the north side of the overpass.
I-84 will be widened to three lanes in both directions between the Karcher Road and Franklin Boulevard interchanges with auxiliary lanes between exits.
"This project is a significant step in our goal of improving I-84 in Canyon County. We have been working with the community for the last year in preparation for this closure," said ITD Southwest Idaho Transportation Program Manager Amy Schroeder. "Our analysis shows a full closure will significantly reduce the overall time to complete work on this area of I-84."
Officials say a detour will be in place on Karcher Road.
Eastbound I-84 will be closed overnight March 15 while the overpass is removed. A detour will begin at 10 p.m. Friday and end at 7 a.m. Saturday.
Westbound I-84 will be closed and traffic will be detoured from 10 p.m. Saturday to 7 a.m. Sunday.
Single-lane restrictions will be in place at night on I-84 from March 12-22. Nighttime work hours begin at 10 p.m. and end at 5 a.m. during the week and 7 a.m. on weekends. All lanes will be open during the day.
Business access on Karcher Road will be open throughout the project.
