The only planned subway service change this Memorial Day weekend directly affecting local stations is that from late evening Friday, May 27 to early Tuesday morning, May 30 there will be no Brooklyn bound service at High Street, as A and C trains will be diverted to the F line between 34th Street-Herald Square in Manhattan to Jay Street-MetroTech in Brooklyn.
The only planned subway service change directly affecting local stations the following work week — early Tuesday morning, May 31 to early Friday evening, June 3 — is that there will be no Brooklyn bound C train service at High Street as C trains will be diverted to the F line between West 4th Street-Washington Square to Jay Street-MetroTech in Brooklyn. A trains should be running normally, so there will be Brooklyn bound service at High Street.
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.
