More Cracks Found In Rods On New Bay Bridge, Integrity Of 400 Remaining Fasteners Called Into Question
Engineers say the rods may need to be repaired or replaced if the problem is found to be widespread.
12 internationally-renowned experts have been assembled at a cost of $500,000 to help design a plan for further rod testing on the Bay Bridge.
The head of a panel overseeing the new $6.4 billion eastern span of the San Francisco-Oakland Bay Bridge is calling for an investigation of additional problems that have surfaced on the bridge.
Caltrans tests indicate that saltwater from the bay may be seeping into the foundation of the eastern span’s tower.
A committee overseeing the new Bay Bridge eastern span project is going to pay another $3 million to fix several mistakes with the span, including rust-stained paint, misaligned rods and now a new problem – malfunctioning maintenance scaffolds.
The corrosion tests are meant to see how the rods will perform over decades and under tension.
An expert says that more than 600 high-strength rods and bolts used to secure seismic equipment on the new span of the San Francisco-Oakland Bay Bridge are harder than the typical levels and are vulnerable to cracking.
