Once again, this coming weekend — 10:45 PM tomorrow (Friday, December 8) to 5:00 AM Monday, December 11 — 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. 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. Apart from that, there are no planned cancellations, route diversions, or station skips that directly affect service at any local stations.
The following work week — Monday, December 11 to Friday, December 15 — each night from 9:45 PM until 5:00 AM, there will be no service in either direction at High Street, as A trains will be diverted to the F line between Jay Street-MetroTech and West 4th Street. During these same hours there will be no service in either direction between Court Street and Manhattan. Use the 2 or 4, as they should, barring any signal problems or the like, be running normally. N trains will, with the same precautions, be running between Court Street and 59th Street in Brooklyn. During rush hours (6:30 to 9:30 a.m. and 3:30 to 8:00 p.m.) each day, 2 and 3 trains will operate at reduced speed in the tunnel between Clark Street and Wall Street, so allow for additional travel time.
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.
