NAMPA, Idaho — The Idaho Transportation Department has reached a milestone in the widening of I-84 in Nampa. Two travel lanes in each direction have been finished in the median, but ITD is advising drivers to plan for significant ramp changes and delays over the weekend as traffic shifts from the outside lanes to the new inside lanes.

Starting June 5 at 10 p.m. and going through June 6 at 10 p.m., eastbound traffic exiting in Nampa must exit at the Karcher/Midland Blvd (Exit 33.) The off-ramps at Exit 35 (Northside Blvd.) and Exit 36 (Franklin Blvd.) will be closed, while Exit 38 (Garrity) will remain open. Eastbound traffic can still access Northside and Franklin Blvd by exiting at Karcher/Midland Blvd. There will be a dedicated ramp running parallel to the interstate with a reduced 40 MPH speed limit. Traffic wanting to access eastbound I-84 will be detoured onto the parallel route to Franklin Blvd., where the on-ramp will be open. Eastbound traffic not exiting in Nampa will have a dedicated thru lane.

On June 6 starting at 10 p.m. and ending Monday at 5 a.m., Karcher and Midland Blvd. will exit and enter I-84 normally. The eastbound off-ram at Northside Blvd. will stay open and the Franklin Blvd. off-ram will be closed. Exiting traffic can access Franklin Blvd. by using the Northside off-ramp and traveling on a parallel route to Franklin. Traffic entering the interstate at Northside Blvd. will be detoured to the parallel route and enter at Franklin Blvd.

The eastbound I-84 traffic shift is part of a two-weekend process to shift all traffic to the new median lanes on I-84. Once traffic has shifted, crews will begin work on improving the outside lanes of I-84. ITD asks all motorists traveling through the work zone to use extreme caution, follow directions on signage, and adhere to the reduced speed limit.

The I-84 Corridor is a vision of current and future improvements to the freeway in Canyon County. Three thru-lanes in each direction and auxiliary lanes between interchanges in Nampa will improve safety and mobility to this congested section of the interstate. Construction in Nampa is expected to be completed in early 2021.
