The New York Transit Museum and the New York Public Library join forces to present a two-location exhibition about New York City's underground infrastructure initiatives in the 21st Century. Examining the magnitude and historical context of eight massive building projects, the exhibition provides New Yorkers a behind the scenes glimpse at their changing city and how these improvements will affect their lives.

Projects explored at the Transit Museum include the Metropolitan Transportation Authority's four mega projects: Fulton Transit Center, East Side Access, the extension of the 7 subway line, and the Second Avenue Subway. At the Library, viewers can learn about the New York City Department of Environmental Protection's Third Water Tunnel and new water filtration plant, New Jersey Transit's new trans-Hudson tunnel, and transit hub beneath the World Trade Center site, spearheaded by the Port Authority of NY and NJ.
