You'll recall that we're spending $4 million to see what the hell is going on with the Bay Bridge's $6.4 billion eastern span. Well, in testing the over 400 steel rods that secure the tower to its foundation, Caltrans officials announced today that they've found one that has fractured.

The Chron reports that it's likely but not definitely because it's been "stewing" in water, causing the 25-foot rod to corrode. The rod has looked suspicious since ultrasonic tests conducted in April, and now we know for sure that it's broken.

Bridge authorities maintain that the span is perfectly earthquake safe, and that all they're doing is protecting against future corrosion and steel failure.
