A significant traffic collision occurred today on the eastbound lanes of Interstate 210 (I-210) near North Rosemead Boulevard in Pasadena, CA. The incident involved two large vehicles: a white Amazon truck and a semi truck, which became jackknifed, leading to major disruptions in traffic flow.

As a result of the collision, multiple center lanes are blocked, causing considerable delays and congestion for drivers in the area. Although the high-occupancy vehicle (HOV) lane has been reopened, the #2, #3, and #4 lanes remain closed while emergency response teams work to clear the scene.

Emergency traffic management units are on-site to coordinate the response and restore normal traffic conditions as quickly as possible. Motorists are experiencing significant backups, particularly during the busy afternoon commute. Additionally, reports indicate that the semi truck is leaking a fluid, prompting precautionary measures to prevent any environmental hazards.

Drivers are advised to seek alternate routes to avoid delays and congestion in the vicinity. The situation is being monitored closely, and updates will be provided as the response continues.
