NYC subway fantasy map

When I have nothing better to do in the subway, I often imagine extensions to the subway system:

* the 2nd Avenue Line (T line).
* extension of the 7 train to the Hudson Yards development.

(these two are already in the city's official plans)

* a line under 125th St in Harlem, to solve the horrible traffic jams.
* access to La Guardia Airport.
* a way of crossing between UWS and UES, without taking a bus.
* better connectivity in Brooklyn (there are lots of line crossings without connections)
* better connectivity between Brooklyn and Queens. Currently, the G and JZ are the only direct connections... Actually, to be precise, many other trains cross over to Queens (AC, 23, etc.), but don't connect to the main Queens lines (namely, 7, E, F, M, NQR). You can imagine extending the Brooklyn M from Middle Village to Jackson Heights.

Somebody in Philadelphia made a PDF map with waaayy more stuff than I ever thought of.
