MARIN COUNTY, CA — If you attempted to drive on Marin's highways on Friday, chances are you were caught in heavier-thank-normal traffic. Local California Highway patrol officials say they responded to "numerous" incidents throughout the day.

"Between 6 a.m. and 4 p.m., we averaged one collision every 11 minutes," CHP Officer Andrew Barclay said. Barclay also offered the below recap of the day's major events:

The first real storm of the winter season made its way through Marin County Friday, leaving wet roadways and frustrated motorists behind. Officers assigned to the California Highway Patrol's Marin Area Office began responding to calls of collisions in the early morning hours before many of us were starting our wet and slippery commutes. At approximately 5:15 AM, officers received a call of an overturned van on US-101 southbound, north of the Spencer Avenue off ramp in Sausalito. Witnesses stated the van had lost control and collided with the center divide wall before overturning and coming to rest blocking the right lanes of the freeway. The driver, 31 year old Justin Hunter of Novato, was transported to Marin General Hospital with minor injuries. The van, which sustained major damage in the collision, was not able to be moved without a tow truck and even then proved to be difficult to remove from the scene. All lanes were cleared at approximately 6:53 AM.

As the commute rush got into full swing, officers began responding to numerous vehicle collisions throughout the county, many of them involving vehicles which had spun out on the roadways. At approximately 8:20 AM officers were dispatched to a call of a collision on US-101 northbound at North San Pedro Road in San Rafael. Responding officers were informed that a 26 foot box truck had collided with the cement center divide wall and then over turned, coming to rest with the box portion of the truck on top of the wall. The force of the collision propelled large sections of the center divide wall along with pieces of the truck and its cargo into the southbound lanes of traffic, striking at least one other vehicle.

Emergency personnel arriving on scene observed 4 of the 5 northbound lanes and 3 of the 4 southbound lanes of traffic were blocked by the truck, debris and vehicles that had stopped to assist. Officers, fire fighters, and tow truck drivers quickly began sweeping and shoveling the southbound lanes in order to clear the way as quickly as possible for commute traffic. All debris was cleared into the #1 lane within 20 minutes allowing some relief to the now stopped commute traffic.
