A motorcyclist was killed Friday morning after slamming into the back of another vehicle on the Bay Bridge and was thrown from his bike.

The driver of the motorcycle, described as a male, was driving west on the Bay Bridge around 10:45 a.m. when he struck the back of a Toyota Corolla, according to California Highway Patrol Officer Tony Tam. The man was ejected from the motorcycle and hit the concrete railing on the north side of the bridge.

The man was pronounced dead at 11:05 a.m.

Traffic was backed up through Albany, according to the CHP. The two right lanes were blocked while emergency workers responded to the scene, Tam said. The two lanes were reopened at 12:30 p.m.

The incident occurred at the Bay Bridge S-curve and speed was a factor.

Some reports say the motorcyclist was traveling at 70 mph. The speed limit on the bridge is 50 mph. In the S-curve, the speed limit is 40 mph.

Tam is reminding drivers to be careful during the holiday season.
