As it was two weekends ago, service between Brooklyn and Manhattan’s East Side, at least above 14th Street, will take on an almost “you cahn’t get theah from heah” quality. There will be no 4 train service in either direction at the Borough Hall station (5 trains don’t come to Brooklyn on weekends; this weekend, they won’t be operating anywhere south of 42nd Street/Grand Central). So, for destinations in lower Manhattan this weekend you have your choice of the 2, 3 (service in Brooklyn will be extended to New Lots Avenue), A, C, R, and (for the Lower East Side) F trains, all of which will be running normally within the affected area. To get to destinations on the East Side of Manhattan served by the 4 or 6 trains (the “Lex”), the MTA advises you to take a Brooklyn-bound 2 or 3 to Atlantic Avenue, change there for a special Manhattan-bound J shuttle (running on the Q track) to the Chambers Street-Brooklyn Bridge station in Manhattan, and change there for an uptown 4, which will be running local up to 125th Street and express north of there. This kerfuffle lasts from 12:01 a.m. Saturday until 5:00 a.m. Monday.
As it was last weekend, the northbound A and C will be running express from 59th Street to 125th Street in Manhattan (the A normally replaces the C for local service during late night-early morning hours). For service to 72nd, 81st, 86th, 96th, 103rd, 110th, and 116th streets, You can ride the A or C to 125th and change for a downtown train to the skipped station, or you can take the 2, 3 or 1 local to a nearby stop on Broadway. During the wee morning hours Saturday, Sunday, and Monday, Brooklyn-bound A trains (there is no C service during these hours) will be skipping 50th, 23rd, and Spring streets. Options for Brooklyn service are the 2 or 3 (or connecting 1 local) and the R.
