Moses Gates took WNYC on a tour of some “ghost” subways sites in the city’s transit system.

The piece includes this cool interactive map of the system’s once-planned routes and abandoned stations. Most of the abandoned stations were taken out of service over time – the exception is the South 4th Street station, which was never completed. A few clicks around the interactive map show how different the Southside might have been if the Depression hadn’t stopped this major expansion (the 6th Avenue (F) and 8th Avenue (C?) lines both would have come out to Williamsburg, where they would have hooked up with Crosstown (G) service).
