NEW YORK CITY—The Empire State Building opened its new, second-floor galleries on Monday, completing the second phase of the $165 million project. Empire State Realty Trust finished the first phase which included a new entrance to the Observatory at 20 W. 34th St. in August last year.Several observation decks dot the city, including at Rockefeller Center, the World Trade Center and ones under construction at Hudson Yards and One Vanderbilt. But incorporating an experiential component, the Empire State Building's interactive galleries hope to lure visitors to the tourist site offering not only views but also drawing upon the building's history. The 102-story, 2.7 million-square-foot tower was designed by Shreve, Lamb & Harmon and originally completed in 1931.
