Located on the West Side of Manhattan on the scenic Hudson River shoreline, Riverside Park South is a massive, multiphase project of sweeping ambition and historic scope. Combining new green space, new infrastructure, and the renovation of landmark industrial buildings, the plan – originally devised by Thomas Balsley Associates in 1991 – is an extension of Frederick Law Olmsted’s famed Riverside Park, carrying it a further 13 blocks beyond its traditional southern boundary. At the same time, the scheme calls for the elevated Miller Highway (long a barrier between the city and its waterfront) to be replaced by an underground tunnel topped by lawns and surface streets, affording unimpeded access from new high-rise apartment buildings and upland neighborhoods to the parks and paths along the river.
