"Suspension bridges are among the most imposing and inspiring structures in the world. The engineering and design required to make these bridges span vast lengths is breath-taking, particularly when many are also built in regions where seismic activity is commonplace. Here, we list the world's Top 20 longest suspension bridges, in ascending order of length, and look at how these wonders of human endeavour came to be built."
"Perhaps the most famous suspension bridge in the world, the Golden Gate Bridge connects San Francisco and Marin County, California, in the US. As well as being the most recognisable suspension bridge to most people, the Golden Gate Bridge is the oldest of its type in this list. Built in 1937, it was built to replace a ferry service across the bay and work began in 1933. It took four years to complete and opened on 27 May 1937."
"A total of 1.2 million rivets were used in the construction of the bridge and its trademark colour is known as International Orange. A team of 38 painters work full-time to maintain the protective paint and prevent corrosion of the metal. A replacement of the bridge's deck was needed between 1982 and 1986 due to the salt in the regular thick fogs that surround the bridge rotting the concrete."
Suspension bridges rank among the most imposing and inspiring structures, requiring advanced engineering and design to span vast distances, often in seismically active regions. The Golden Gate Bridge links San Francisco and Marin County, completed in 1937 after construction from 1933; 1.2 million rivets were used and its trademark colour is International Orange. A team of 38 painters maintains protective paint to prevent corrosion, and the deck was replaced between 1982 and 1986 due to salt damage from frequent fog. The Verrazzano-Narrows Bridge spans the Narrows between Staten Island and Brooklyn, constructed starting in 1959 with the upper level completed in 1964; it carries 202,000 vehicles daily, reaches 211 metres high, and originally bore a single-'z' spelling.
