Regarding replacement of parts of the San Francisco Bay Bridge, above says
"Construction of the bridge decks and the materials that went into them are
a Made in China affair. California officials say the state saved hundreds of
millions of dollars by turning to China."

"Zhenhua put 3,000 employees to work on the project: steel-cutters, welders,
polishers and engineers. The company built the main bridge tower, which was
shipped in mid-2009, and a total of 28 bridge decks ? the massive triangular
steel structures that will serve as the roadway platform."

I'm sure that's some quality steel there.
