In this artist rendering created by Visualhouse and released by Hudson Yards, the Hudson Yards redevelopment as it will be seen while looking northeast while on the Hudson River is shown. With the ceremonial groundbreaking on Tuesday, Dec. 4, 2012, the transformation of the largest undeveloped property in Manhattan from a railroad storage yard into a sleek new neighborhood of spiky high-rises and graceful parks has begun. The first office tower is expected to be completed in 2015. (AP Photo/Visualhouse via Hudson Yards)
