All northbound lanes of Highway 101 re-opened at 6:00 p.m. Tuesday after a crash near the Marin-Sonoma County line shut down portions of the highway for hours.

A big rig loaded with cement flipped over just before Petaluma Boulevard.

Three other vehicles were involved in the crash and four people were seriously hurt.

Investigators are still piecing together what happened.

The CHP recommends drivers take Highway 37 to Lakeville Highway to avoid the backup.
