I’m declaring this weekend — late night Friday, April 14 to early morning Monday, April 17 — to be a “green light weekend,” as there are no planned cancellations or route diversions directly affecting service at any local stations. 2 trains will be running on a reduced schedule, every twenty minutes, on Saturday and Sunday, but 3 trains should be running normally except during late nights, when they don’t serve Brooklyn.
The following work week — early morning Monday, April 20 to late evening Friday, April 25 — late nights from Monday to Tuesday through Thursday to Friday, there will be no Manhattan bound service at High Street, as Manhattan bound A and C trains will be diverted to the F line between Jay Street-MetroTech and West 4th Street-Washington Square. 3 train service, which normally ends in Brooklyn at around midnight and resumes early the following morning, will be ending earlier, around 9:30 PM, each evening Monday through Thursday. 2 trains will make all 3 train stops in Manhattan and in Brooklyn to Franklin Avenue-Medgar Evers College, and 4 trains will make all 3 train stops between Atlantic Avenue-Barclays Center and New Lots Avenue.
Always check MTA Info for unplanned service changes that may affect local service or service on other parts of your trip, or for planned service changes that affect stations to or from which you may be traveling.
