This time it’s for real. Maybe. On Thursday, the 14th St. Busway will go live, bringing with it an unknown amount of change and perhaps chaos the neighborhood. Once it’s in effect, the Busway will mean that the only way to get crosstown westbound without interruption will be on 13th St. since neither 11th St. nor 15th St. cut across town uninterrupted. Will 13th St. become a nightmare? We shall soon see.
