OAKLAND, CA - JULY 12: Workers walk on the eastern span of the newly constructed San Francisco-Oakland Bay Bridge on July 12, 2013 in Oakland, California. Workers began paving the roadway of the newly constructed east span of the San Francisco-Oakland Bay Bridge just days after bridge officials announced that the opening of the span would be delayed once again as work continues to install large steel saddles over two seismic safety devices to fix a problem with broken bolts on two shear keys. The bridge has been under construction since 2002 with an estimated price tag of $6.3 billion and will have the world's tallest Self-Anchored Suspension (SAS) tower once completed.

OAKLAND (KCBS) – Caltrans is now performing stress corrosion tests on a random sampling of rods on the eastern foundation of the Bay Bridge.
The testing of 13 rods on the Bay Bridge was prompted by early breakage of bolts made from similar materials.
“The material that snapped was grade A354 BD bolts. These are also grade A354 BD bolts,” said engineer Bill Casey. “They’re estimated from a different time period.”
