As of 6:15 on December 13 there's a massive traffic jam on Arlington Avenue in Berkeley. A motorist on the scene, parked in the street since no cars can move, reports that a police officer attempting to direct the motionless traffic told her that a big semi has been blocking Arlington, a major artery. Cars have been diverted to the area's narrow twisting side streets, where they've been stuck, some for an hour and a half. Our reporter was marooned at Arlington and Yosemite.
