Construction Update

Bridge Maintenance

The Idaho Transportation Department is maintaining on several bridges between 11th Ave and Franklin Blvd in Nampa.

ITD will improve the overpass on 11th Ave., the road above the Phyllis canal, and the overpass at Franklin Blvd. The maintenance work is expected to extend the lifespan of each bridge.

This work was paused for the winter and will resume in spring of 2022. Click here to learn more.

Northside Boulevard Interchange - SPUI

The interchange at Northside Boulevard has been replaced with a Single Point Urban Interchange to accommodate more traffic and reduce delays.

A SPUI, or Single-Point Urban Interchange is traffic configuration controlled by a central traffic signal. The Northside SPUI is underneath I-84 with a signal directing all turning movements from a single point.

ITD reopened the SPUI on Sunday, May 9 at 6 a.m. Watch on FACEBOOK LIVE.
