Before Franklin Roosevelt was elected to a third term in office in 1940, 5 of 10 longest suspension bridges in the US were built.
Before Marilyn Monroe sang Happy Birthday to JFK in 1962, 9 of the 10 had been open at least 5 years and the 10th, the Verrazano, had been under construction for nearly 3 years.

They were all built before I was born.
Throughout the years there have been retrofittings, additional spans built, and the original span of the Carquinez Bridge was replaced this century.
Here they are with their opening year:
Verrazano-Narrows Bridge, NY 1964
Golden Gate Bridge, CA 1937
Mackinac Bridge, MI 1954
George Washington Bridge, NY-NJ 1931
Tacoma Narrows Bridge, WA 1950
Carquinez Bridge, CA 1927, 1958, 2003
San Francisco-Oakland Bay Bridge, CA 1936
Bronx-Whitestone Bridge, NY 1939
Delaware Memorial Bridge, DE-NJ 1951
Walt Whitman Bridge, PA 1957
Is anyone else surprised that these bridges have been standing between half and three-quarters of a century?
I’ve been over 6 of the 10 – though obviously not driving. I’ve been over the NY-NJ- DE bridges many, many times, with the Verrazano being my least favorite. It also happens to be the longest suspension bridge in the US.
Which have you been over?
