The National Weather Service tweeted out that snow was starting to stick on the freeway around 9 a.m. Monday.
CHP says it had to stop pacing while officers responded to several collisions in the area.
Several vehicles were stuck on the highway when the closure was ordered, and shortly after 4 pm, Caltrans announced that the snow had been cleared enough to release six or seven of the stuck vehicles at a time in the northbound direction.
