"On August 5, we're launching two new overnight interborough bus routes: the Bx99, between Woodlawn in the Bronx and the West Village in Manhattan, and the M99 between East New York in Brooklyn and Hell's Kitchen in Manhattan. These two routes, along with the previously launched B99, will operate every 20 minutes from approximately 1-6 a.m."
