Just like last weekend, this weekend, from 9:45 PM Friday, October 26 to 5:00 AM Monday, October 29 there will be no service in either direction at the 4/5 platforms at Borough Hall, as 4 trains are terminating and originating at Brooklyn Bridge station Manhattan, and 5 trains don’t serve Brooklyn on weekends. Use 2, 3, R or N trains for service to or from Manhattan, and into Brooklyn. 3 trains will be making 4 stops to and from New Lots Avenue.
The following work week, Monday, October 29 to Thursday, November 1, each night from 9:45 PM to 5:00 AM there will be no service in either direction at Clark Street or at the 2/3 platforms at Borough Hall. Use 4, R, or N trains as options. During these same late night hours each night there will be no Manhattan bound service at High Street, as A and C trains to Manhattan will be diverted to the F line between Jay Street and West 4th Street. Use Manhattan bound 2, 3, 4, Q (see below) R, or N trains as options. Each early morning, 12:01 to 5:00 AM, Tuesday, October 30 to Friday, November 2 there will be extra service in both directions at Court Street and at Jay Street, as Q trains are being diverted to the R/N line during those hours. Happy Halloween!
