Same old, same old. Just like last weekend, from 11:45 p.m. Friday, April 15 to 5:00 a.m. Monday, April 18 there will be no service in either direction at the 4/5 platforms at Borough Hall, as 4 trains will terminate and originate at Brooklyn Bridge/City Hall in Manhattan, and 5 trains do not serve Brooklyn on weekends (there will be no 5 train service anywhere on the system this weekend). During the same time period, A and C trains running in both directions will be diverted to the F line between Jay Street-Metro Tech and West 4th Street, so there will be no service in either direction at High Street. For service to or from Manhattan, use the 2 or 3 to or from Clark Street or Borough Hall, the R or (late night) N to or from Court Street, or the A or C to or from York Street or Jay Street-Metro Tech.
The following week, Monday, April 18 to Friday, April 22, there are no planned cancellations, route diversions, or station skips directly affecting service at any local stations, except that each night from 11:45 p.m. to 5:00 a.m. there will be no G train service between Hoyt-Schermerhorn and Church Avenue. Use the A or F as alternatives.
