A traffic collision involving a semi truck with double trailers occurred today on Interstate 10 West near Singleton Road in Calimesa, CA. The incident took place during the morning commute, leading to significant traffic disruptions. The big rig left the roadway and impacted nearby areas, resulting in the closure of eastbound lanes on Calimesa Boulevard, which were blocked by cones. Additionally, Calimesa Boulevard was closed at Cherry Valley to facilitate emergency response efforts.

Despite the challenges, westbound lanes on Interstate 10 remained open, allowing some traffic to continue moving. California Highway Patrol (CHP) units were dispatched to manage the scene and direct traffic around the affected area. A tow truck was requested to assist with the semi truck, which was reported to be blocking Calimesa Boulevard after leaving the westbound lanes of Interstate 10.

Motorists are advised to expect delays and potential backups in the area as crews work to clear the scene and restore normal traffic conditions. The CHP is actively managing the situation to minimize congestion and ensure a safe environment for all drivers. Updates will be provided as the situation develops.
