2) Golden Gate Bridge, San Francisco
At the time it was completed it was the longest bridge in the world. Connecting Marin County to the north with San Francisco to the south, the project was first proposed in 1872. It didn’t get approved until 1924, when the War Department, which owned both sides of the Golden Gate straight, issued a temporary permit. Construction finally began in 1933. The cables are of the utmost importance in the engineering of such a massive suspension bridge. The cables for the Golden Gate were designed by the same company as the Brooklyn Bridge. Its famous international orange color is one of the most striking features, and makes for amazing photos against the blue sky or San Francisco fog. In May 1937, the opening was celebrated for a week. On its 50th Anniversary 50,000 people were expected. 800,000 people showed up and the arch flattened out from the excessive weight.
