Canyon County, ID – Drivers along westbound I-84 are facing significant delays today after a two-vehicle injury crash near milepost 40, according to the Idaho State Police. Troopers remain on scene, and traffic is heavily backed up as emergency crews work to clear the roadway.
According to Idaho State Police, the crash happened earlier this morning along the westbound lanes near the Parma and Caldwell area, creating a slowdown that stretched through the surrounding corridor. Officials said motorists should expect major delays and be prepared to reduce speed when approaching the scene.
Troopers reported that at least one person was injured in the collision, though no additional details about the extent of injuries were immediately released. Emergency responders are continuing to direct traffic while managing the crash investigation and medical needs.
Drivers are being advised to use alternate routes whenever possible to avoid long backups along I-84. The agency emphasized the importance of staying alert, keeping a safe following distance, and giving first responders plenty of room to work as they clear vehicles and debris.
The slowdown is expected to continue for some time as lane restrictions remain in place. Commuters heading toward western Canyon County or approaching from Caldwell and Nampa may experience extended travel times.
Motorists who are familiar with the corridor are encouraged to detour through local surface roads until the interstate fully reopens. Officials have not yet provided an estimate for when normal traffic flow will resume.
