OAKLAND — A Bay Bridge toll collector was killed and the driver of a truck arrested Saturday after his box truck slammed into a line of vehicles, then crashed into the toll plaza, the California Highway Patrol reported.

Bay Bridge lane still closed in wreck’s aftermath The multi-vehicle wreck caused massive traffic delays throughout the day.

Daniel Berk, 32, of Foster City, who was ejected and seriously injured from the crash, was subsequently arrested on suspicion of driving under the influence and manslaughter, according to the CHP.

A statement by Gov. Jerry Brown identified the toll taker as Si Si Han, 46. Her city of residence was not released, but a public records search indicated that she lived in San Lorenzo.

Han was a California Department of Transportation employee for more than a decade and is survived by her husband, Ryan, and their 10-year-old daughter, Ashly, according to the governor’s statement.

Berk and his passenger were thrown from the truck when the box truck from Monarch Truck Rentals struck and demolished the No. 14 toll booth. Berk suffered serious injuries; the extent of the passenger’s injuries was not immediately known, CHP Officer Vu Williams said. The two people from the truck and four people from other vehicles were taken to Highland Hospital in Oakland, he said.

“Investigators were able to determine there were signs of impairment,” Williams said of the driver. “They obtained a warrant for a blood draw.”

The wreck occurred in the westbound lanes of Interstate 80 at the toll plaza about 5:15 a.m. and resulted in several other, non-life-threatening injuries, Williams said. The truck, described as a medium-sized rental box truck, slammed into the back of at least one line of vehicles waiting at the toll plaza, causing a chain reaction, Williams said. The truck then continued toward the toll plaza and destroyed the booth. Six vehicles, including the truck, were involved in the wreck.

“Based on the damage, it wasn’t a low-speed collision,” Williams said.

Immediately after the crash, toll lanes 14 to 17 were blocked, the CHP said. Ultimately, the toll plaza’s 10 rightmost lanes — six cash/FasTrak lanes, two FasTrak lanes and two bus lanes — were closed, Williams said. In addition, access from northbound Interstate 880 to the bridge was limited. The lanes were eventually opened late Saturday, according to the CHP.

The cause of the wreck was under investigation. As of midday, officers had not spoken to the driver of the truck, Williams said.

Despite a number of recent attacks using box trucks to strike pedestrians, authorities do not believe this was an intentional act, Williams said. “We haven’t developed any indication of that.”

A receptionist at Monarch said she was not allowed to talk to the media about the incident and took a message for her supervisor.

Berk’s Facebook page claimed that he was a member of the International Alliance of Theatrical Stage Employees Local 134 out of Santa Clara County. He posted numerous concert and music jobs he worked.

Capitol Corridor bus service from Emeryville to San Francisco was also suspended because of the crash, the agency said on Twitter.

Gov. Brown said flags at the Capitol will be flown at half-staff in Han’s honor.
