A "big rig" semitruck rolled over on the Bay Bridge, causing major delays and blocking four lanes of the eastbound section, according to multiple agencies.
The incident occurred just before the Treasure Island exit on the lower deck, according to California Highway Patrol San Francisco and other agencies.
The resulting extra-heavy traffic seriously disrupted the evening commute for thousands of drivers. After putting out numerous updates about the overturned truck's status, CHP tweeted at 8:35 p.m. that the vehicle had been removed and all eastbound lanes were once again open. Drivers should still expect significant delays to continue for some time.
Elsewhere on the Bay, the Golden Gate Ferry was suspended as of 4:45 p.m. because of the bad weather.
Winds reaching speeds of 70 mph battered the Bay Area, as a rare system that fell just shy of bomb cyclone status made landfall Tuesday afternoon.
