What it was
A proposed cross-Manhattan expressway, commonly associated with planner Robert Moses, linking the Hudson and East River crossings.
Multiple versions would have cut through or above dense neighbourhoods, displacing residents and businesses. The proposal received repeated official study and political support but faced growing community opposition.
Existence timeline

The road becomes part of a wider metropolitan motorway programme.
Officials study elevated and depressed alignments through occupied neighbourhoods.
Residents, businesses and preservation advocates organise against displacement.
The state removes the expressway from its plans.
Why it ended
Political support collapsed amid organised resistance, changing planning values and rising concern over displacement. New York State formally removed the route from plans in 1971.
Last confirmed trace
Planning maps, models, government records and the urban fabric it would have demolished preserve the conflict.
What it left behind
Its defeat became a defining episode in the shift from urban motorway construction toward preservation and community-led planning.
