1984 Louisiana World Exposition New Orleans, May 12 - Nov. 11, 1984. Its 82-acre setting along the banks of the Mississippi River, will dazzle the imagination with a wonderland of fact and fantasy. For many people, the first glimpse of the 1984 Louisiana World's Fair will be looking down Canal Street toward the river. The familiar view of the International Trade Mart and the Spanish Plaza will be dramatically changed. Flags, banners, balloons, music, and entertainers lead you to the entrance area. At night, bright lights, fireworks, and even laser beams draw visitors down Canal Street to the Fair.
