OAKLAND -- High tide Tuesday morning temporarily stranded a car parked on a frontage road near Bay Bridge, authorities said.

It was not clear if the two people associated with the car were inside and got a wet wake-up or found it underwater when they came to get it about 8 a.m.

The California Highway Patrol said the car was parked along the road north of the bridge metering lights either Monday night or Tuesday morning. The road leads to several radio towers.

It was not known how badly the car, believed to be a Toyota was damaged, but the motorists were able to drive it away as the tide went out, about 9:30 a.m.

No injuries were reported.
