Westbound travelers going over the bridge, listen up: a Safeway big rig truck overturned on the Bay Bridge, which has since caused an INSANE amount of traffic back-up. According to KTVU, the big rig tipped over at the new s-curve portion of the bridge on the top part of the span. The accident happened around 2:30. It's blocking "4 out of 5 lanes."
Safeway products, it seems, are strewn all over the road.
Anyway, this won't be cleaned up for at least two hours. Instead, you might want to take the San Rafael Bridge or find your way to 101 as a detour if you're coming home to SF.
