New York City’s best subway map just got better.

OnNYTurf‘s clickable, dragable, searchable Google mashup showing the subway and PATH lines in scale relation to the surface streets now shows — ready for this? — the exact locations of all the entrances to the 116 subway stations in Manhattan. (The four-platform, 22-entrance Fulton Street/Broadway-Nassau complex is shown above.)

Speed your ride by waiting at the right end of the platform. Choose your destination station with greater precision. Here’s how it works: Pull up the map, then zoom in as far as you can by clicking on the "+" sign at the upper left hand corner of the map and you will arrive at this level of detail.

This map won’t help answer questions such as why the West 4th Street station’s entrance is actually at West 3rd Street, but it does document that fact visually.
