Express Bus Services from The Bronx & Westchester

My latest creation is not a video, but rather, a diagrammatic map of express routes serving The Bronx and Westchester. It's a large PNG file, but if you know anyone who's been wondering about express routes in The Bronx (especially that elusive X32), check this out.

Original image: PNG, 637K, 5760×3600
Linked image: 1600×1000. I'll post the bigger one as soon as I find a way to do so.

EDIT
I've made a little something to fill the white space on the right side of the map.
