This weekend (Friday, September 16 at 11:45 p.m. to Monday, September 19 at 5:00 a.m.) A and C trains running in both directions will be re-routed to the F line between Jay Street-Metro Tech and West 4th Street, so there will be no service at the High Street station. For stops in Manhattan below West 4th, use the 2 (the 3 will not be running this weekend) from Clark street or Borough Hall), the 4 from Borough Hall, or the R or (late night) N from Court Street. For those traveling into Brooklyn, the 4 will make all 3 stops between Nevins Street and New Lots Avenue.
The following work week (Monday, September 19 to Friday, September 23) each night from 11:45 p.m. to 5:00 a.m., Manhattan bound A trains (there is no C service late at night) will be diverted to the F line from Jay Street to West 4th Street, so there will be no service to Manhattan from High Street. For stops in Manhattan below west 4th use the 2 from Clark Street or Borough Hall (the 3 will not be running), the N (which replaces the R late at night) from Court Street, or the 4 (the 5 does not serve Brooklyn late at night) from Borough Hall.
