Karcher Overpass construction continues
The old Karcher Overpass has been removed and crews are building the foundation for the new center pier and abutments (walls on the side of the bridge). Crews are driving steel rods (called "piles") into the ground during this process. Pile-driving is noisy and causes vibrations similar to a garbage truck. Pile driving will be completed by the end of April.

Traffic update: I-84 will be reduced to one lane in both directions at night between Karcher/Midland and Northside interchanges this week while the contractor pours concrete for the center pier.
Utility work begins on Northside Boulevard

Idaho Power is working on utility lines on Northside Boulevard. The overhead transmission lines will be moved underground as a part of the new interchange design.

Traffic update: Idaho Power and their subcontractor may close lanes on Northside Boulevard . Please contact (208) 334-8002 or 84corridor@itd.idaho.gov if you have questions about the utility work.



Overnight I-84 detours planned this week

Idaho Power is installing a new transmission line for the Skyway substation in Caldwell. This work is not related to I-84 improvements.

Traffic update: I-84 will be closed at night April 22-26 between the Franklin Road Interchange and Karcher/Midland Interchange. A detour route will be in place from 10 p.m. to 5 a.m. each night.
