The driver of a truck that dumped a sticky material on the Bay Bridge has been cited after the mishap caused the closure of all westbound lanes during this morning's commute, leading to delays that are expected to last through the afternoon.

California Highway Patrol spokesperson Officer T.J. Shively says that they started getting calls about white paint, epoxy, and paint cans dumped across all the lanes of westbound Interstate 80 just west of the Fremont Street off ramp at around 4 a.m.

By 4:15 a.m., CHP had closed all westbound lanes into SF, and started to clean up what KRON4 reports is drywall spackle.

Caltrans crews dumped sand on the epoxy-like mess and used a sweeper truck in an effort to clear the roadway, as thousands of westbound commuters remained trapped, motionless, in their cars.

The effort went well enough that one lane was reopened by 5 a.m., and the remaining lanes were reopened by 6:45. According to Shively, however, the early-morning backup is expected to have repercussions that last all day and "into the afternoon," so if you're heading from the East Bay to SF at any point today, BART might be your best bet.

Shively says that the truck driver, who didn't stop at the scene of the spill, was eventually tracked down by CHP and cited for driving with an unsecured load.

He says the driver will be hit with a hefty bill, too, as “Whenever somebody spills some type of load, they are held responsible for the clean up."
