Before construction on the Hudson Yards megaproject officially kicked off in 2012, the area on Manhattan’s west side between 30th and 34th streets wasn’t home to much. There were apartment buildings (including a handful of high-rises), some office towers, the remnants of the elevated railway that became the High Line, and—crucially to the redevelopment story—the West Sid Yard, where Long Island Rail Road trains were stored and served.

Seven years later, the physical transformation of the landscape has made the neighborhood barely recognizable. The gleaming towers comprising Related and Oxford Properties Group’s Hudson Yards parcel have gone vertical, with more of the rail yard due to be decked over in the coming years. Many of those low-rise apartment buildings and small businesses are gone, and even more high-rises—a bunch of which are outside of the Related development—have sprouted throughout the neighborhood.

To get a sense of how profound the change is, take a look at the before-and-after shots below, taken by photographer Max Touhey, who’s been shooting the site since the beginning.
