The United States gave China 50 billion yuan to build a bridge for it in China. Do you dare to say that China made it badly?

San Francisco Oakland Bay Bridge. The title of infrastructure madman is not for nothing.

In March, 2006, California Department of Transportation invited public bidding for the construction of San Francisco New Bay Bridge to replace the San Francisco Bay Bridge damaged in the 1989 7. 1 earthquake. The New Bay Bridge is the largest single-tower suspension bridge in the world, all of which are steel structures. Its design strength can resist an earthquake of magnitude 8, and its service life exceeds 100 years. It is planned to be completed and opened to traffic in 2065,438+03. When completed, this bridge will become a landmark of San Francisco Bay together with the Golden Gate Bridge.

In 2006, Zhenhua Heavy Industry stood out from the competition with companies from developed countries such as Japan, South Korea and embroidery, and successfully undertook the construction of the steel tower of the bridge and all 45,000 tons of steel structures. It is the first time in the history of steel bridge construction in the United States that the United States handed over all the steel structures with extremely high quality requirements to Zhenhua Heavy Industry. This is also the first time that China enterprises have undertaken the construction of such a complex and large-scale bridge steel structure, which has made great contributions to improving the bridge manufacturing level at home and abroad.

2011In mid-July, all the steel structures of San Francisco New Bay Bridge built by China Zhenhua Heavy Industry were sent to the United States, several months ahead of the contract. As a reward, the United States will pay an additional $30 million. This is the first time that China's manufacturing industry has entered the world's large-scale steel structure market, and it is also the largest steel structure project undertaken by China Company overseas.
