Bay Bridge officials said Wednesday that the retrofit for broken anchor rods on the eastern pier of the new suspension span had been completed. Custom steel saddles replaced the function of the rods, which snapped in March after being placed under tension. The cost of the retrofit was about $25 million.
Controversy continues about why the rods fractured. A recent independent report by Yun Chung and Lisa Thomas, two Bay Area engineers, said that the official explanation by Caltrans and transportation oversight officials overlooked the effects of corrosion on numerous rods on the new span, which they say remain at risk. The report also said that bridge officials failed to account for irregular hardness profiles in some rods – a problem that could lead to future problems.
