2 killed in crash on westbound Bay Bridge; police activity causes traffic backup, CHP says

SAN FRANCISCO (KGO) -- Two people are dead after a crash between a car and a big-rig on the westbound direction of the Bay Bridge, the California Highway Patrol told ABC7 News.

The accident happened on the upper deck of the bridge on Westbound 80, just east of Treasure Island just after 11 p.m. Wednesday. It was a part of a series of incidents that stretched police activity into Thursday morning, causing a massive backup on the Bay Bridge heading into San Francisco.

Authorities confirm to ABC7 News that someone has been taken into custody and all lanes have been reopened.

However, traffic was backed up on the Bay Bridge and into the East Bay all throughout the morning.

Police activity began on the bridge at 10 p.m. Wednesday before the CHP says there were two crashes, both in the same area.

The first crash happened around 11:13 p.m., which involved three vehicles resulting in minor injuries.

The second crash occurred nearly ten minutes later at 11:21 p.m. The CHP said the second crash involved a vehicle and a big-rig where two people have died.

The situation on the Bay Bridge is also impacting AC Transit riders. The service tweeted to expect delays.

Commuters are advised to take BART into San Francisco to avoid the backup.
