This weekend, from 9:45 Friday evening, November 30 to 5:00 AM Monday, December 3 there will be no service from Manhattan to High Street, as Brooklyn bound A and C trains will be diverted to the F line between West 4th Street Jay Street-MetroTech. From 11:00 PM Friday to 5:00 AM Monday Brooklyn bound Q trains will replace N and R trains between Canal Street in Manhattan and 36th Street in Brooklyn, so use the Q (transfer at Canal) for service to Court Street or Jay Street-MetroTech. Service at other local stations should be normal.
The following work week — Monday, December 3 to Friday, December 7 — each night from 11:00 PM to 5:00 AM there will be no service from Manhattan to High Street, as Brooklyn bound A trains will be diverted to the F line between West 4th Street Jay Street-MetroTech, and C trains do not run late at night. During these same hours there will be no A train service between Jay Street and Utica Avenue; shuttle buses will provide alternate service. Each night from 10:45 PM to 5:00 AM there will be no Manhattan bound service at Court Street or from the N/R platforms at Jay Street. Use the 4 from Borough Hall, the 2 or 3 from Clark Street or Borough Hall, or the A from High street or Jay street as options. Each night from 11:00 PM to 5:00 AM Brooklyn bound Q trains will run on the R/N line from Canal Street to DeKalb Avenue, so will provide extra service to Court Street and the R/N platform at Jay Street.
