Subway disruptions this weekend — Late Friday night, March 22 to early Monday morning, March 25 — are minimal. Late nights Friday to Saturday, Saturday to Sunday, and Sunday to Monday there will be no 4 train service at Borough Hall, as 4 trains will not be going to or from Brooklyn during these hours. 2 trains should be running normally, except that from early morning to early evening Saturday and Sunday they will be on a reduced schedule. 3 trains, which normally do not serve Brooklyn late at night, will fill in for the 4 during the late nights, running to and from New Lots Avenue. If you’re traveling to or from Manhattan you can switch between the 4 and the 2 or 3 at Fulton Street.
The following work week — Monday morning, March 25 to Friday evening, March 29 — there will be no late night service at Clark Street or at the 2/3 platforms at Borough Hall, as 2 trains will not be running between Chambers Street in Manhattan and Atlantic Avenue-Barclays Center, and 3 trains do not serve Brooklyn late at night (except on the preceding weekend). 4, A, C, N, and R trains should be running normally. Late nights Monday to Tuesday through Thursday to Friday there will be no G train service between Hoyt-Schermerhorn and Church Avenue. To get to or from G train stops, use the F train to or from Church Avenue. Coney Island bound F trains will be skipping all stations between Jay Street-MetroTech and Church Avenue. To get to these stations take a Coney Island bound F to Church Avenue and take a Manhattan bound F back to the skipped station.
These are the PLANNED service changes for this weekend and for the following week.
