6. When It Opened, the Verrazano-Narrows Bridge Was the World’s Largest Suspension Bridge

At 4,260 feet, the equivalent to 14 football fields and four-fifths of a mile, the Verrazano-Narrows Bridge was the world’s largest suspension span when it opened in 1964. It lost its title in 1981 to Humber Bridge in London and is now the eleventh longest in the world. In the United States, however it still remains the longest. It was also the world’s heaviest bridge at the time it opened, weighing 1,265,000 tons.
