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.”
