This long Martin Luther King weekend, from 10:45 PM Friday, January 12 to 5:00 AM Tuesday, January 16, there will be no 2 or 3 train service (meaning no service at Clark Street or on the 2/3 platforms at Borough Hall), which will be a fact of life every weekend until sometime next summer. As usual, during the absence of 2/3 service, 4 and 5 (5 trains don’t usually serve Brooklyn on weekends) will provide alternate service to and into Brooklyn. From 9:30 PM Friday to 5:00 AM Monday (but not Monday night) F trains will not serve York Street in DUMBO or the F stations in the Lower East Side in either direction, with shuttle buses replacing the F between the LES stations and West 4th, where you can catch an A, C or D (which is being diverted to the A/C line to and from High street at Jay Street-Metro Tech), or change to a shuttle bus to the LES there. There will also be shuttle bus service between Jay Street and York Street.
The following week, Monday, January 15 to Friday, January 19, the following late night changes will be in effect. From 9:30 PM until 5:00 AM there will be no service in either direction at High Street, as A trains are diverted to the D line between 59th Street-Columbus Circle and the F between 34th Street-Herald Square and Jay Street-MetroTech and C train service ends early. Those traveling to or from the North Heights may use York Street in DUMBO (A and F service) or the 2 to or from Clark Street. There will be no 3 trains each night 9:45 PM to 5:00 AM; 2 and 4 trains will provide alternative service, with 2 and 4 trains making 3 train stops for those traveling to or from Brooklyn. R train service will be suspended each night from 9:45 PM to 5:00 AM; use N trains instead.
For planned service changes that may affect travel on other parts of the system, either during the weekend or the following week, and for unplanned disruptions, see MTA Info.
