The Trans-Mississippi Exposition was held in North Omaha from June 1 to November 1, 1898. The exposition drew more than 2 million visitors. It required the construction of attractions spanning 100 city blocks, including a ship-worthy lagoon, bridges and magnificent (though temporary) buildings constructed of plaster and horsehair. The Exposition also featured a number of sideshows, including Buffalo Bill's Wild West Show and the Everleigh House. Run by Ada and Minna Everleigh, the house continued operating until 1900, when the two women moved to Chicago.
