This coming weekend–from 11:45 p.m Friday, July 18 to 5:00 a.m. Monday, July 21, Brooklyn bound F trains will be diverted to the A/C line from West 4th Street in Manhattan to Jay Street-MetroTech, so no service from Manhattan to York Street in DUMBO. If that’s your destination, you can either get off at High Street and walk down the hill, or ride to Jay Street and change there for a Manhattan bound F back to York. To get to Brooklyn from the Lower East Side stops on the F, take an uptown F to West 4th and change for a Brooklyn bound train there.
The following week (Monday, July 21 to Friday, July 25) there are no planned cancellations, route diversions, or station skips that directly affect service at any local stations. For planned service changes that may affect travel on other parts of the system, either during the weekend or the following week, see MTA Info or The Weekender.
