A traffic collision involving a tow truck sent an unoccupied vehicle flying onto Bay Area Rapid Transit tracks along Interstate 580 in Castro Valley on Tuesday afternoon, prompting lane closures, transit interruptions, and hours of cleanup during the evening commute, according to authorities.
The California Highway Patrol said the incident occurred just before 3 p.m. on westbound I-580 near Eden Canyon Road and involved three vehicles. Preliminary findings indicate the car had been secured on the bed of a tow truck when the crash occurred. During the collision, the vehicle came loose and was thrown from the tow truck, landing on the adjacent BART tracks.
The tow truck driver sustained major injuries and was transported to a hospital. Authorities said his condition was not immediately known. No other injuries were reported, and the car that landed on the tracks was unoccupied at the time of the crash.

The collision caused significant traffic disruptions across the area. Several lanes of I-580 were shut down in both directions as emergency crews responded and worked to stabilize the scene. The closures contributed to heavy congestion during peak commute hours. Lanes were gradually reopened, with full access restored around 6 p.m.
BART service was also affected as a result of the vehicle landing on the tracks. Train service was initially halted between the Castro Valley and West Dublin/Pleasanton stations to ensure safety while crews assessed the situation. Service later resumed shortly after 6 p.m., though trains were limited to a single track through the affected area, resulting in major delays between the two stations.
Cleanup efforts continued for several hours. Crews ultimately used a crane to safely lift and remove the vehicle from the tracks, allowing transit operations to partially resume while repairs and inspections were completed.
Authorities said the cause of the crash remains under investigation. The incident highlights the ripple effects a single roadway collision can have across multiple transportation systems, particularly in heavily traveled corridors shared by highways and rail infrastructure.
