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.
- Construction may be noisy at night.
- Occasional nighttime restrictions may be scheduled on interchange ramps.
- Additional closures will be scheduled at the Northside Interchange in 2020.

Transportation is an essential service during this pandemic. It is critical that we have a reliable highway network to keep goods and services moving. Connecting you with healthcare providers, and making sure your grocery stores can restock daily, are some of our state’s highest priorities.
At this time, construction is continuing. I-84 is an important corridor and we are committed to delivering these essential services. All lanes of I-84 are open during the day. No road closures on I-84 are currently planned. We will continue to monitor the situation and make changes as needed.
The COVID-19 pandemic has created a dynamic, ever-evolving situation for all of us . We will continue to monitor and make changes to ensure we can safely conduct our essential work. Even now, we are committed to our Mission: “Your Safety. Your Mobility. Your Economic Opportunity.”
Thank you. Stay healthy, stay well, and wash your hands!
Extended single-lane closures
As a result of the statewide stay-home order, ITD will extend single-lane closures on I-84 during the weekdays for construction. Decreased traffic volumes provide crews with additional opportunities to work in the corridor.
What to expect:
- Eastbound I-84 single-lane closures: Mon. – Fri., 7 p.m. to 6 a.m.
- Westbound I-84 single-lane closures: Mon. – Fri., 8 p.m.to 7 a.m.
- One travel lane in each direction will remain open 24/7.
