Construction crews continue to transform the former busiest train station in the world, into the new St. Louis Aquarium in St. Louis on January 17, 2019. The $187 million family entertainment facility will have more than 1 million gallons of water and feature more than 13,000 aquatic animals, including more than 60 sharks and rays. In the 1980's, the facility was transformed into a hotel, shopping center, and entertainment complex, until closure two years ago. The aquarium will open later this year. Photo by Bill Greenblatt/UPI
