I-84 Projects in Canyon County
The Idaho Transportation Department is beginning to construct improvements to Interstate 84 between the Karcher Interchange and Franklin Boulevard Interchange in Nampa.
Work on I-84 is in multiple stages of design and construction. An environmental study and design plans are also underway for I-84 between Caldwell and Karcher.
Construction plans
Plans for I-84 between the Karcher and Franklin Boulevard interchanges include:
- Adding a third lane in each direction of I-84.
- Adding auxiliary lanes in each direction of I-84 between interchanges.
- Replacing the Northside Interchange with a Single Point Urban Interchange for safer, more efficient travel.
- Rebuilding the Karcher Road Overpass, railroad/irrigation canal bridges and the Mason Creek Structure.
- Widening the eastbound off-ramp at the Franklin Boulevard Interchange and modifying signals to allow two left-turn lanes onto the westbound on-ramp.
