Happy birthday to Benjamin Franklin, who was born on this day in 1706! We’re celebrating this occasion with these photographs of the bridge that’s borne his name since 1955.Construction on the Philadelphia and Camden-connecting Benjamin Franklin Bridge began in 1922 (these photos of its construction are from 1924 to 1925). At the time of its completion in 1926, it was the world’s longest single span suspension bridge, and it would remain so until the 1929 completion of the Ambassador Bridge connecting Detroit, Michigan to Windsor, Ontario. These photographs are from the Hagley Library’s Dallin Aerial Survey Company photographs (Acc. 1970.200) collection. To view more images from this collection, which includes over 7,800 aerial views of towns, cities, and notable landmarks (mostly in the Mid-Atlantic states), visit its page in our Digital Archives by clicking here.
