New York City has a number of ambitious development and infrastructure projects underway.
Manhattan's most recent transportation upgrade came in the form of the glistening, $4.5 billion Second Avenue subway line, which opened on January 1.
On the other side of the island, Hudson Yards - the most expensive real estate development in American history - is under construction. And on an island in the East River, Cornell University is building a glassy tech campus with classrooms, a hotel, restaurants, and shops for future graduate students. By the middle of this century, the city will look different, and will likely attract even more new residents and tourists than today.
