The Idaho Transportation Department will close 10th Avenue under Interstate 84 for three nights starting Wednesday, Sept. 23.

  • Sunday and Monday, Sept. 27 and 28:Flaggers will direct traffic at the 10th Avenue ramp intersections from 8 p.m. to 5 a.m. each night while crews paint lane lines.

The closures will allow crews to pave the roadway underneath I-84 and install overhead sign structures on the ramps.

“By Tuesday morning, drivers will have two lanes in each direction and a center turn lane on 10th Avenue with a new driving surface,” Resident Engineer Styles Salek said. “We are excited to get these lanes open and know the community has been looking forward to this.”

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 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.

Construction on I-84 in Caldwell is ahead of schedule and all lanes are expected to be in their final configuration by early 2027.
