A and C trains will be running normally to and from High Street and Jay Street-MetroTech this weekend, but once again, from 11:45 p.m. Friday, April 22 to 5:00 a.m. Monday, April 25 there will be no service in either direction at the 4/5 platforms at Borough Hall, as 4 trains will terminate and originate at Bowling Green in Manhattan, and 5 trains do not serve Brooklyn on weekends (there will be no 5 train service anywhere on the system this weekend).
The following week, each night Monday, April 25 to Friday, April 29, Brooklyn bound 3 train service will end at 9:30 p.m. and there will be no 3 trains running from 10:00 p.m. to 5:00 a.m. However, 2 trains will be running as normal, so there will be service at Clark Street and at the 2/3 platforms at Borough Hall. Also, each night from 11:15 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.
