South Williamsburg’s South Fourth Street Station has never been used. Its construction was halted by World War II and rails were never installed, leaving behind a big concrete shell of an underground structure. In recent years, dozens have been arrested trying to sneak peeks of the graffiti that now lives in the station, as provided by the Underbelly Project.
