We Californians just can't drive in the rain, period. According to Action News SF, "CHP now says accident on the lower deck of the Bay Bridge involves 5 vehicles, none of which are a bus." Which would explain the MASSIVE backup of angry vehicles outside SFist HQ on Third Street, (Seriously, every single driver has the heft of their weight on their car horns. Jerks.) So, there will be long delays getting back home, East Bay dwellers. Might want to re-think your route, or stay in the city for a bit longer.
