405 Fwy Reopens After Crash Involving Big Rig Leaves Most Lanes Closed in Long Beach for Hours

All lanes have been reopened on the 405 Freeway in Long Beach hours after a multivehicle crash involving a big rig triggered the closure of nearly all lanes on Tuesday, snarling traffic in the area.

The crash took place just after 9:30 a.m. on the southbound 405 at the connector to the southbound 710 Freeway, according to the California Highway Patrol.

A total of three vehicles were involved in the collision, CHP's log stated. No injuries were immediately reported.

The big rig -- which ended of the center divider wall -- began leaking fuel, spilling about 75 gallons of Diesel onto the roadway as of 11:20 a.m., according to CHP. A hazmat team was called to the scene.

The semi was carrying a load of pipes on the truck's flatbed, many of which ended up on the freeway after the crash, Sky5 aerial video showed.

A SigAlert was issued around 9:45 a.m., and the southbound freeway plus four northbound lanes were shut down for hours. All lanes were reopened just before 3:30 p.m., according to CHP.

The lane closures triggered a massive traffic backup in the aftermath of the collision, according to the aerial footage. Traffic remained heavy in the area into the afternoon.

The cause of the crash was under investigation.
