New I-84 lanes in Caldwell ready to open following ramp closures Friday night

CALDWELL - The Idaho Transportation Department will shift traffic onto the permanent eastbound lanes between Centennial Way and Franklin Road on Friday night. This will allow motorists to drive on the new eastbound Interstate 84 lanes, including the new side of the 10th Avenue Interchange bridge, in Caldwell.

To complete the traffic shift, three eastbound ramps will close Friday, Oct. 9, at 10 p.m. to Saturday, Oct. 10, at 6 a.m.

What to expect:

The 10th Avenue and Franklin Road eastbound off-ramps will close. Motorists will detour to Centennial Way (Exit 27). If you miss this exit, drivers will need to continue to Karcher Road (Exit 33) in Nampa.

The 10th Avenue eastbound on-ramp will close. Motorists will detour to the Centennial Way eastbound on-ramp to enter I-84.

Motorists may remember a similar shift onto the new westbound lanes in June 2024. This time, crews will shift traffic on the eastbound side. Only one night of ramp closures is needed to move traffic onto the new lanes.

"The shift marks a major step toward finishing the project." Resident Engineer Styles Salek said. "Crews have been building the 10th Avenue Interchange bridge since 2023. Now, motorists will get to drive on it."

The project began in November 2023 and is expected to finish by summer 2027. The project includes:

• Widening I-84 to three lanes in each direction with auxiliary lanes between interchanges.

• Replacing the 10th Avenue Interchange.

• Removing one westbound on-ramp at the 10th Avenue Interchange.

• Updating the pedestrian overpass.

• Building a sound wall along Hannibal Street.

• Adding a traffic signal at the westbound ramps at the Centennial Way Interchange.
