The Viaduct RailPark is coming soon, which will transform sections of the long-abandoned stretch of rail line that runs through the Chinatown and Callowhill neighborhoods into a “grittier take on NYC’s High Line.” Construction is still slated to begin later this year, but starting right now, you and yours can get involved in the Viaduct’s metamorphosis, through a call for submissions for art installations that will adorn several locations of the public space.
