What is telling is how much of the city outside of Manhattan is not covered by more than one line — which means when that line fails or is out of service, that much more of the city is in a subway desert.

Lots of the “subway deserts” shown here aren’t actually transit deserts once you take bus service into account.

Manhattan's east side is a notorious subway desert.

@joshgreenman Slightly misleading because the "Queens" label is prominently in a subway desert. But yes, still underserved.
