Pontchartrain Beach:
Pontchartrain Beach was an amusement park located in New Orleans, Louisiana, on the south shore of Lake Pontchartrain. It was founded by Harry J. Batt Sr. and later mananged by his son, Harry J. Batt Jr. It opened in 1928, across Bayou St. John from an existing amusement resort at Old Spanish Fort. Pontchartrain Beach's original location is the present-day lakefront neighborhood of Lake Terrace. In the early 1930s, subsequent to the construction of a seawall extending from West End to the Industrial Canal that created a new shoreline for Lake Pontchartrain, Pontchartrain Beach was moved to a new location at the lake end of Elysian Fields Avenue, a location formerly offshore of Milneburg.
The park was originally racially segregated and earmarked for "Whites Only"; another lakefront resort was reserved for "Coloreds", Lincoln Beach. Pontchartrain Beach was integrated in the early 1960s, leading to the closure of Lincoln Beach.
Pontchartrain Beach included a beach, amusement rides (including a large roller coaster, the Zephyr), and concession stands. The park featured live music concerts, including many local musicians and touring national acts such as Elvis Presley.
Other rides included the Zephyr Junior, Smoky Mary, The Wild Maus, Musik Express, Log Ride, The Ragin' Cajun (a modern, looping steel coaster), The Bug, Paratrooper, Calypso, "The Airplanes", Haunted House, Ghost Train, bumper cars, Ferris wheel, the Monster, Trabant, Sky Ride, Hard Rock, Galaxie, Laff in the Dark, Magic Rainbow, Red Baron, and many others. In addition to rides, there were also the summertime shows which changed every few years (Skipper & Dolly dolphin show, Great American High Dive Show, Merlin's Magic Rainbow Show). For a few years there was also a fairly large petting zoo with many farm animals and a huge red barnhouse.
Just outside of "The Beach" gates was the "Bali Hai" south seas "Tiki" style restaurant. Another popular restaurant was the Ship Ahoy, which featured hamburgers and seafood.
Pontchartrain Beach was closed September 23, 1983, due to decreasing attendance, rising insurance costs, pollution concerns in the lake, and the impending competition of the 1984 World's Fair.
Several of the rides ended up in Gulf Shores, Alabama, at a small amusement park including the Airplanes and many Kiddieland rides which was subsequently wiped out by Hurricane Ivan in 2004.
The land formerly housing the park is now occupied by the University of New Orleans Research & Technology Park, home to the Navy's Space and Naval Warfare Systems Center (SPAWAR) and the UNO Advanced Technology Center office building.

Lincoln Beach amusement park:
Lincoln Beach was an amusement park in New Orleans, Louisiana, functioning from 1939 through 1965. The park was for the area's African American population during the Jim Crow era of racial segregation.
Lincoln Beach was located along the shore of Lake Pontchartrain near Little Woods, in a portion of the Eastern New Orleans section of the Ninth Ward of New Orleans that was little developed in the 1930s. The land where Lincoln Beach was located was deeded to the city by Samuel Zemurray in 1938 and purchased within a year by the Orleans Levee Board. The Levee Board first designated this section as a swimming area in the lake for "colored" New Orleanians, then built out additional land in the lake for the amusement park to be built on. The park was similar to the then "whites only" Pontchartrain Beach amusement park, only on a smaller scale. It featured various rides, games, restaurants, a swimming pool in addition to lake swimming, and frequent live music performances. In the last decade, Fats Domino was repeatedly a featured musical act.
Pontchartrain Beach was desegregated in 1964, and business declined rapidly at Lincoln Beach, which, having been rendered obsolete, closed soon afterward. Although there have been various proposals to redevelop the Lincoln Beach site, the decaying ruins of the park have remained vacant for decades.
