From 11:45 PM Friday, July 14 to 5:00 AM Monday, July 17 there will be no service in either direction at High Street, as A and C trains will be diverted to the F line between West 4th Street and Jay Street-Metro Tech. There will also be no 2 or 3 service at Clark Street or Borough Hall, so your options are to use the 4 or 5 to or from Borough Hall (the 5 will serve Brooklyn on weekends when there is no 2 or 3 service, which should be until sometime in 2018), the R or (late night) N to or from Court Street, or the A, C, or F to or from Jay Street or York Street. For those traveling into Brooklyn, the 4 and 5 will make all 2 or 3 stops.
The following work week (Monday, July 17 to Friday, July 21) there are no planned cancellations, route diversions, or station skips directly affecting service at any local stations, except that C train service will be ending at 10:00 PM.
For planned service changes that may affect travel on other parts of the system, either during the weekend or the following week, see MTA Info or The Weekender.
