If you’re in town over the long July Fourth weekend, you’ll find complications in taking the subway to either the east or west side of Manhattan. Beginning with the East Side: there will be no service to or from Brooklyn on the 4/5 line from 12:01 a.m. Saturday, July 2 until 5:00 a.m. Monday, July 4. The 4 train will not be running south of the Brooklyn Bridge stop in Manhattan, and the 5 train, which normally does not run to or from Brooklyn on weekends, will not be running in Manhattan at all. For trips to or from lower Manhattan (Canal Street or below), use the 2, 3, A, C, F (for Lower East Side stops), or R. For trips to the East Side above Canal (except for Lower East Side stops on the F), take the R to Canal and change there for an uptown 4 or 6. Returning to Brooklyn, take the 4 or 6 to canal, and change there for the R.
As it has been for the past several weekends, there will be no service on the uptown A and C lines to the following Upper West Side stations: 72nd, 81st, 86th, 96th, 103rd, 110th, and 116th streets. Your best bet is to take a 2. 3, or 1 local to a nearby stop on Broadway. This only lasts until midnight Sunday. Service back to Brooklyn is not affected.
