In 1870, the Louisville and Nashville Railroad was constructed through the southernmost section of Harrison County, Mississippi, connecting New Orleans, Louisiana, and Mobile, Alabama. A northern transportation route into south Mississippi was provided by the Gulf and Ship Island Railroad at the turn of the 20th century. These railroads provided an inexpensive means for moving passengers as well as goods, and opened south Mississippi to both industrial and recreational development.Rapidly progressing lumber and seafood industries transformed the Mississippi Gulf Coast in the 1920s, and people arrived from throughout the United States to take advantage of the economic boom. Northern tourists were attracted to the Mississippi Gulf Coast because of mild winters and cool sea breezes in summer,
