STUDIO CITY (KTLA) -- A big rig truck and a minivan collided on the eastbound Ventura (101) Freeway in Studio City early Tuesday, shutting down the freeway and creating a traffic tie-up that lasted for hours.

According to witnesses, a big rig hauling two trailers filled with sand slammed into the center divider of the eastbound 101 freeway just past the Laurel Canyon Boulevard exit around 6:10 a.m.

The truck partially went through the center divider, struck several vehicles on the westbound side, bounced back to the eastbound lanes and landed on top of a minivan.

The driver of the minivan was treated at the scene by paramedics and taken by ambulance to a hospital emergency room. The driver was first thought to be under the influence of drugs or alcohol and was taken into custody. However, he was later released and was not charged with any crime, according to Officer Miguel Luevano of the California HIghway Patrol.

The driver of the minivan was seriously hurt in the crash, according to officials.

The driver of the big rig was not injured however fire crews had to use a ladder to rescue him from the cab of his truck.

The drivers of several other vehicles were also treated by paramedics.

Their conditions are not yet known.

The 101 freeway in both directions in Studio City was backed up for several miles, adding more than an hour to the commute of thousands of frustrated drivers.

CHP investigators, looking into the exact cause of the crash, closed several lanes in both directions.

Chunks of concrete ended up on freeway lanes, and some other vehicles were damaged.

Authorities did not immediately release the names of the trucker or the minivan driver.

The freeway was re-opened at 10:30 a.m.
