A traffic collision involving three vehicles occurred today during the evening rush hour along the transition from eastbound Interstate 210 (I-210) to southbound State Route 57 (SR-57) in Glendora, CA. The vehicles involved included a grey Toyota Tundra, a white 2025 Buick, and a third vehicle that remains unidentified.

The incident led to significant traffic disruptions, with two lanes on the transition road closed, causing delays and congestion for commuters. Multiple units from the California Highway Patrol (CHP) were dispatched to manage the scene and direct traffic. A signal alert was issued for approximately one hour, warning drivers of the backups in the area.

Tow trucks were called to assist with the vehicles involved in the collision, further impacting traffic as they worked to clear the roadway. The transition from I-210 to SR-57 was temporarily blocked, leading to frustration among drivers navigating through the area.

By 8:23 PM, the CHP announced that the transition road had reopened, allowing traffic to resume its normal flow. However, motorists should remain cautious and aware of potential residual delays as the area clears from the earlier incident.

Drivers are encouraged to seek alternative routes if possible to avoid congestion in the vicinity of the traffic collision.
