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.

Updates
New traffic pattern on westbound I-84 at Franklin Blvd exit.
On August 4, the Idaho Transportation Department will reconfigure lanes near the Franklin Boulevard Interchange.
In the new configuration, the left lane will no longer merge and will remain a travel lane. The far right lane will end, becoming an off-ramp to Franklin Blvd. View a map of the new traffic pattern.
The new configuration will keep two travel lanes open on I-84 during construction in Canyon County.
