Compton, CA (July 2, 2026) – A three-vehicle accident brought all lanes to a stop on northbound I-405 near Wilmington Ave in Compton, California, on Tuesday, June 30, beginning around 11:29 a.m.
The collision involved a black Jeep Compass, a white Honda Accord, and a white BMW. The Jeep blocked the HOV and the number one lane, while other vehicles stopped in the middle lanes. At one point, the HOV and lanes one through five were all held, with all lanes coming to a full stop.
Both the black Jeep and the white Honda sustained broken front and rear axles and required tow trucks. Emergency units arrived, and fire personnel cleared the road. A Honda driver did not respond when contacted, according to information relayed at the time of the wreck.
No names, ages, or confirmed injury details were included in the initial report on the collision. Further details about those involved in the crash had not been made public as of this report. What caused the accident is still being examined, and more information will be shared as it becomes available.
We hope everyone involved is safe and receives any care they may need.
What Happens When All Lanes Are Blocked on a California Freeway?
A full freeway closure, even a temporary one, can create significant traffic backups within minutes on a heavily traveled corridor like I-405. When all lanes stop simultaneously, vehicles behind the point of blockage have no option to merge around the obstruction, which means the queue can extend for several miles before traffic managers or alternate routes can relieve the pressure. The longer the lanes stay blocked, the harder it becomes to clear the backup even after the road reopens.
Broken axles are among the more serious forms of vehicle damage seen in freeway crashes, because a vehicle with a compromised axle cannot be driven off the road under its own power. Each affected vehicle requires its own tow, and coordinating multiple trucks in a live lane environment takes time, especially when tow availability is limited.
Crashes in the middle lanes of a multi-lane freeway present unique clearance challenges, since emergency units and tow operators must work around active or partially active traffic on both sides while securing the vehicles and the people involved.
