Newscopy: "Peak hour morning traffic on the lower deck of the Bay Bridge is paralyzed by three smashed mobile scaffolds - weighing six tons - which form a barrier across all lanes. Seven workmen were injured, one so seriously he may die. Accident occurred when brakes failed on one of the air-powered scaffolds, pushing the other two westward along the bridge.".
