Today, the majority of Jacksonville's water based industry is located north of the Hart Bridge. During the mid 20th century, the downtown riverfront resembled cities like San Francisco, Seattle, San Diego and New York City. A bustling district filled with wharfs, seafood markets, shipyards, and wholesale water-based industry.
During this era, the Southbank had a street grid, shipyards like the Northbank, and marshland where MOSH and Friendship Fountain are now located. By the end of the decade, the Southbank had begun to see massive redevelopment with the construction of Prudential Tower (now Aetna), Baptist Medical Center and the Fuller Warren Bridge.
