Industry, CA (June 20, 2026) – An early morning traffic collision involving multiple vehicles temporarily shut down southbound Interstate 605 near the Valley Boulevard off-ramp in the City of Industry.
According to dispatch records, the accident was reported at approximately 3:59 a.m. on June 19. Initial information indicated a silver Kia and a silver Lexus sedan were involved. Additional reports referenced a white sedan and a truck that had reportedly been stopped on the freeway before the collision occurred.
An automated crash notification from a mobile device was also received near the same stretch of roadway shortly after the initial reports. As crews worked in the area, all southbound lanes of I-605 near Valley Boulevard were temporarily held, creating significant traffic disruptions. Later updates indicated that lanes three, four, and five remained restricted before traffic conditions gradually improved.
Tow trucks were requested to remove the damaged vehicles from the freeway. By approximately 5:07 a.m., all lanes had reopened, and the vehicles had been cleared from the roadway.
The number of people involved and the extent of any injuries were not disclosed in the initial report. Investigators continue to review the factors that contributed to the collision.
We hope those affected recover quickly and fully.
Why Freeway Lane Closures Can Lead to Heavy Congestion
When a collision blocks freeway lanes, traffic patterns can change rapidly, creating backups that extend well beyond the immediate roadway section. Even a temporary closure can reduce traffic capacity enough to slow vehicles for miles, particularly during periods of increasing traffic volume.
Lane restrictions are usually necessary when damaged vehicles are being removed, and roadway conditions are being evaluated. In some cases, traffic may be briefly stopped altogether to allow equipment and personnel to work safely. Once lanes reopen, congestion can persist as vehicles gradually move through the previously restricted section.
Reviews of freeway collisions commonly include vehicle positions, traffic flow, roadway conditions, and available physical evidence. Examining these factors helps create a clearer picture of how the vehicles came together and the sequence of movements that followed.
