I-84 Projects in Canyon County
Work on I-84 is in multiple stages of design and construction. Construction in 2019 and 2020 will 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.
Design plans and an environmental study are also underway for I-84 between Caldwell and Karcher/Midland.
What to expect during construction
- All lanes of I-84 will be open during the day.
- One lane may be closed at night in each direction of I-84.
- Eastbound lane restrictions will be in place from 10 p.m. to 5 a.m. on weekdays and from 10 p.m. to 7 a.m. on weekends.
- Westbound lane restrictions will continue until 6 a.m. on weekdays and until 7 a.m. on weekends.
- Traffic will be shifted around the work zone from week to week.
