The Metropolitan Transportation Authority has maps of the entire New York City Subway system showing all five of the city's boroughs at web.mta.info. The map allows users to zoom in on smaller areas. From the main map, users can access individual routes by clicking on the icons above the map.
From the map menu, users can get detailed maps showing landmarks and subway stops of particular neighborhoods. The menu also has a PDF version of the full map, a map showing weekend service changes and a map showing the full subway system in conjunction with New Jersey Transit buses and PATH trains that service the city.
