Aug. 23 update: Weekend closures scheduled for Aug. 24-Aug. 27 have been postponed. New dates will be shared in the new future.
BOISE– Ongoing improvements to the Interstate 84/Karcher Interchange in Nampa will require two closures the week of August 20. Motorists should plan ahead and consider an alternate route on the following dates:
Wed., Aug. 22 at 8 p.m. to Thurs., Aug. 23 at 5 a.m.: The interchange will be closed while crews install new traffic signals at the Midland Boulevard/Karcher Bypass intersection and remove two overhead signs. Midland Boulevard, Karcher Bypass, Exit 33 A, 33B and the westbound entrance ramp will all be closed to traffic. Motorists will be detoured via Nampa/Caldwell Boulevard and the Karcher Connector.
Fri., Aug. 24 at 8 p.m. – Mon. Aug. 27 at 5 a.m.: Exit Ramp 33A will be closed to traffic while crews reconstruct and modify the ramp. Westbound I-84 motorists will be directed to use Exit 35 at Northside Blvd instead of Exit 33A during this closure.
The project includes the following improvements:
*Eliminating exit 33B and adding lanes at exit 33A/Midland Blvd.
*Adding a second southbound lane to Midland Blvd.
*Adding a second left turn lane from the Karcher Bypass to southbound Midland Blvd.
*Upgrading sidewalks and traffic signals
