BOISE— Segments of the Interstate 84 Karcher Interchange in Nampa will be closed overnight Oct. 23 and 24 as crews install new overhead signs.
Detours will be in place during construction.
- On Tues., Oct. 23, the Midland Blvd. bridge over I-84 will be closed at 8 p.m. and will reopen to traffic Wed., Oct. 24 at 5 a.m. Crews will be installing a new overhead sign structure. Pedestrians will need to use an alternative route while the structure is installed.

Reconstruction of the interchange will be complete in early November and is designed to improve traffic flow and safety in this highly traveled area. Project improvements include:
*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
*Permanently removing the westbound off-ramp (Exit 33B)
The I-84 corridor in Nampa is a very active construction zone with multiple projects occurring in the same vicinity. ITD encourages drivers to slow down, pay attention, and give construction crews space to safely work.
