Update: Although it’s not noted on the MTA website, we’re told that a sign at the Clark Street station says it will be closed all day today, November 23, Thanksgiving Day. Apart from that, today there are no planned cancellations, route diversions, or station skips directly affecting service at any local stations, although trains will be running on Sunday schedule. The remainder of the long weekend, from 11:30 Friday evening, November 24 to 5:00 AM Monday, November 27, there will be no service on the G train in either direction between Hoyt-Schermerhorn and Church Avenue. Once again, from 10:30 PM Friday to 5:00 AM Monday there will be no 2 and 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.
The following back-to-work week, Monday, November 27 to Friday, December 1, each night from 9:30 PM to 5:00 AM there will be no 2 or 3 service in either direction between Brooklyn and Manhattan, meaning no service at Clark Street. Alternative service will be provided by 4 and 5 trains, the former extending its run to New Lots early and the latter running to and from Brooklyn and making all local stops in Brooklyn.
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.
