Bridge Comes to San Francisco With a Made-in-China Label... The assembly work in California, and the pouring of the concrete road surface, will be done by Americans. But 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...California decided not to apply for federal funding for the project because the “Buy America” provisos would probably have required purchasing more expensive steel and fabrication from U.S. manufacturers. China, the world’s biggest steel maker, was the front-runner, particularly because it has dominated bridge building for the last decade.
