From 11:45 p.m. Friday, February 20 to 5:00 a.m. Monday, February 23 there will be no 4 train service in either direction between Brooklyn Bridge in Manhattan and New Lots Avenue in Brooklyn. This means no service on the 4/5 platform at Borough Hall, as 5 trains don’t serve Brooklyn on weekends. To get to or from destinations on the East Side of Manhattan above 14th Street your best bet is to switch between the 4 and the R or (late night) N at 14th. For service to or from Manhattan below 14th, use the 2/3, A/C (but see below) or R/N. For those traveling into Brooklyn, 3 train service will be extended to New Lots. Also this weekend, Manhattan bound C trains will be re-routed to the F line between Jay Street and West 4th. A trains and Brooklyn bound C trains should be running normally, so there will be service in both directions at High Street. There are no other planned changes directly affecting service at local stations this weekend.
The following week, from 11:00 p.m. to 5:00 a.m. each night Monday, February 23 to Friday, February 27 there will be no G train service between Hoyt-Schermerhorn and Church Avenue. A and F trains will provide alternate service. There are no other planned changes directly affecting service at local stations during the week.
