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.
