Faulty bolts could lead to a delay in the opening of the Bay Bridge. Caltrans noticed problems with bolts and found that the bolts had cracked. Of the 98 bolts already tightened, 30 have failed. According to the San Francisco Chronicle, workers will be tightening all 288 bolts and then testing them. According to Tony Anziano, Caltrans’s toll bridge program manager, repairs could take one or two months. Mr. Anziano noted that the manufacturer might be responsible for part of the expense, but that the budget for the bridge also has funds set aside for unanticipated repairs.
The bolts were supplied by Dyson, an Ohio company, but it was clear whether Dyson manufactured the bolts or simply marketed them.
