A broken anchor rod rises up next to still-tensioned rods on a shear key on the new Bay Bridge Friday afternoon May 3, 2013. Caltrans showed off the rods and some of the techniques they are using to monitor and test other installed anchor rods as they design a fix for the compromised hardware.

I tap my anchor bolts with a small sledge hammer, they make a unique sound when the threads are pulled or the bolts are fractured, My anchor bolts are about 1 1/2’ diameter. They anchor tall silos.
I remember when Oldsmobile tried converting a gas engine to a diesel, we mechanics would literally pull the rocker covers off, tap each head bolt and often they would just pop up with a thunk, all it took was a hammer tap. Too much compression in a diesel for gasoline engine sized head bolts.

Ya see, in earthquake country, they want their bridges to collapse cleanly, so there’s no twisted mess afterward, like last time.....

They built the bridge because the old one “wasn’t safe” in an earthquake. $6.4 Billion and we are right back where we started, almost. We still have to pay off the $6.4 billion!

A new bridge and bolts are already breaking? I would take a different bridge.

Where were the bolts made? The same factory producing the made-in-China crap hardware sold at the big-box stores? You can easily snap the head off those screws by hand without any power tool.

The KSFO morning show was going over this a while back. Ironically the bolts weren't made in China even though a good portion of the metal work did come from China. These bolts were “Made in the USA”. The problems seem to stem from the casting process. They were reheated twice for some reason effectively destroying the temper of the metal making it brittle in some cases.

While that affair was being talked about a CHP officer called in. He claimed to have arrested 2 fellows in a stolen car, who were high as a kite on heroin. That in and of itself wasn't particularly odd. It was what they did for a living that he was concerned about. One fellow was a metal worker and the other was welder both workers on the Bay Bridge.

He took them in, booked them and went about his business. He said he checked in about them some weeks later. You guessed it they were back at work on the Bay Bridge and most likley still using heroin. They apparently got a slap on the wrist and the union helped them retain their jobs.

God help anyone caught on that eastern span during a good shaker. The stage is set for a potentially catastrophic failure with substantial loss of life depending on the time of day. To add insult to injury it was also brought out that corners were cut in the casting of the concrete for the pilings as in using substandard concrete etc.

There already have been small news stories surfacing now and then about Cal-Trans safety inspectors falsifying inspection reports but those seem to disappear quickly. That bridge has the record of being the longest public works project in the history of California.

I guess if you end up driving that span regularly it might be wise to carry a life preserver and something to aid your self in cutting your way out of your car if you survive the drop into the bay.
