A major traffic incident unfolded in Rosemead, California, after a semi-truck crashed and overturned onto the Metrolink tracks alongside the westbound Interstate 10 Freeway, disrupting both highway traffic and rail service. Emergency crews responded during the early morning hours to secure the scene and begin recovery operations.

According to the California Highway Patrol, the crash was reported at approximately 3:00 a.m. near Del Mar Avenue. Initial reports indicate the semi-truck overturned onto the adjacent Metrolink tracks, prompting the closure of the westbound carpool lane and two left lanes of the freeway while crews worked to remove the vehicle and assess the damage.

Authorities have not confirmed what caused the crash, and the circumstances leading up to the incident remain under investigation. Early information indicates no other vehicles were involved, and the truck was not pulling a trailer at the time of the collision. The driver was able to exit the vehicle, though officials have not released detailed information regarding the extent of any injuries.

Because the overturned truck came to rest on the railroad tracks, Metrolink service through the area was temporarily affected while officials inspected the tracks and coordinated with emergency responders. Recovery crews worked to safely remove the truck before normal rail operations could resume.

Motorists traveling through the area experienced significant delays as traffic was diverted around the lane closures. Drivers were encouraged to seek alternate routes, reduce speed near the emergency scene, and give first responders adequate space to work safely.

Investigators are expected to examine the crash scene to determine the factors that contributed to the incident. Additional information regarding roadway reopening, any injuries, and the official cause of the crash may be released as the investigation continues.
