Where the Collision Happened: Westbound I-580 Near Strobridge Ave
The Strobridge Avenue off-ramp connects westbound Interstate 580 with the local Castro Valley and Hayward street network. Drivers approaching the exit may be slowing, changing lanes, or positioning their vehicles while through traffic continues along the interstate.
A blockage in the first lane can affect traffic well beyond the original collision point. Drivers approaching the scene may need to merge into neighboring lanes while responders work near moving vehicles.

Why Front-End Damage Helps Clarify a Crash Sequence
Damage location can provide investigators with important information about how two vehicles came into contact. Major front-end damage to the Honda Accord may help identify its direction of movement and the angle of impact.
Investigators can compare that damage with marks on the pickup truck and evidence found in the blocked lane. The initial dispatch information does not establish which movement led to the collision.
How This Crash Is Investigated
CHP investigators may document vehicle damage, debris, tire marks, lane positions, and where each vehicle stopped. Those details can help establish the point of impact and reconstruct the moments before the crash.
Statements from the drivers and witnesses may also be compared with the physical evidence. Because the collision occurred near an off-ramp, investigators may review whether either vehicle was exiting, changing lanes, or continuing westbound before contact.
