An accident involving a tractor-trailer led to the closure of all the northbound lanes of the 405 Freeway for a period of several hours. This caused the slowdown of all the traffic in the San Fernando Valley area last Thursday, according to this report from NBC Los Angeles.
The big rig jack-knifed at about 4:40 a.m. on the 405 Freeway near the connector ramp with the 101 Freeway. The exact cause of the single-vehicle crash is not yet known. It’s possible that the truck’s driver tried to divert to the connector ramp at the last minute, causing the truck to go out of control and jack-knife.
The accident took up most of the northbound lanes of the 405. As a result, all those lanes had to be closed as the accident was investigated and the wreckage was removed. This means traffic on the northbound lanes of the 405 Freeway was stopped up near Ventura Boulevard.
Witnesses reported to the California Highway Patrol that the driver was spotted running away from the wreck, heading toward the Ventura Highway. Why he was fleeing the scene is not immediately known. This crash resulted in slow traffic in the San Fernando Valley region for most of Thursday morning.
