CALDWELL - The Idaho Transportation Department will close the eastbound ramps at the Interstate 84 10th Avenue Interchange beginning March 25. The closures will allow crews to rebuild the ramps and connect them to the new lanes on I-84.

The 10th Avenue eastbound on-ramp will close Wednesday, March 25. The eastbound off-ramp is expected to close in early April. Each ramp will remain closed for approximately three months while crews rebuild the connections. During this time, motorists will detour using the Centennial Way or Franklin Road interchanges on I-84.

"Closing the eastbound ramps allows crews to focus on rebuilding these connections as quickly as possible," Resident Engineer Styles Salek said. "We know this will be a big change for drivers, and we appreciate the public planning ahead and using the detours while this work is underway."

The I-84 widening project in Caldwell began in November 2023 and includes:

• Widening I-84 to three lanes in each direction with auxiliary lanes between interchanges.
• Replacing the 10th Avenue Interchange.
• Removing a westbound on-ramp at the 10th Avenue Interchange.
• Refurbishing the pedestrian overpass.
• Building a sound wall along Hannibal Street.
• Adding a signal at the westbound ramps at the Centennial Way Interchange.

The speed limit in the I-84 work zone is 55 mph. With crews, trucks and heavy equipment operating close to traffic, ITD urges motorists to slow down, stay alert and follow all posted signs.

Construction on I-84 in Caldwell is expected to be complete in 2027. For more information, visit itd.idaho.gov/project/84-centennialtofranklin or call (208) 334-8002.
