The big news this weekend — late Friday evening March 18 to early Monday morning, March 21 — is that there will be no 2 or 3 train service to or from Brooklyn. This means that, apart from no service at Clark Street as elevator repairs continue, there will be no trains at the 2/3 platforms at Borough Hall. To make up for this, 5 trains, which normally don’t serve Brooklyn on weekends, will make all 2 stops between Borough Hall and Flatbush Avenue-Brooklyn College. Meanwhile, 4 trains will make all 3 stops between Atlantic Avenue-Barclays Center and New Lots Avenue. These are the only planned service changes directly affecting service at any local stations. If, now that it’s spring, you’re planning a jaunt to Coney, note that the F train will not be running between Church Avenue and Coney Island-Stilwell Avenue. Take the N, which should be running normally, instead.
The following work week — early Monday morning March 21 to late Friday evening March 25 — will see a couple of changes. Late nights Monday to Tuesday through Thursday to Friday there will be no 3 train service in either direction. During these times, 2 trains will make 3 stops between 96th Street in Manhattan and Franklin Avenue-Medgar Evers College, while 4 trains will make 3 stops between Atlantic Avenue-Barclays Center and New Lots Avenue. These same late nights there will be no Brooklyn bound service at High Street as A and C trains will be running on the F line between West 4th Street in Manhattan and Jay Street-MetroTech. Use York Street in DUMBO or Jay Street as options, or take the 2, 4, N. or R, all of which should be running normally.
These are the planned service changes directly affecting service at local stations. 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.
