2. Ponte Vecchio – Italy:
You don’t walk over the Golden Gate Bridge expecting to find a market or a shopping mall up there. But centuries ago, it was common for shops and even houses to stand one the second story of a bridge. The most prominent example that still exists is probably Ponte Vecchio in Florence, Italy. Rebuilt after a flood in 1345, a 1565 upgrade added a second story to the stone segmental arch bridge spanning the Arno River. It was in the second story that workshops and houses filled the extra space, stretching sometimes wider than the original bridge. Ponte Vecchio is the only one of its kind in Florence that survived World War II.
1. Golden Gate Bridge – San Francisco:
The four-year project to span the Golden Gate strait and connect San Francisco to Marin County culminated in what was the world’s longest (4,200 feet) and tallest suspension bridge when this Bay Area landmark opened in 1937. The Golden Gate would keep those records until the 1960s. The Joseph Strauss Art Deco suspension bridge design is famous today in large part because of something a bit out of the norm in the bridge world: color. Golden Gate was painted “International Orange” partly to match the warm coastal surroundings and also to stand out against the horizon for boaters.
