This coming weekend there will be diversions affecting service at the Court Street, High Street, Jay Street-Metro Tech, and York Street stations. Service at the Clark Street (2 and 3 trains) and Borough Hall (2, 3, and 4), barring unforeseen problems, will not be affected. Just like last weekend, Manhattan bound A and C trains will be re-routed over the F line from Jay Street to West 4th Street, so there’s no Manhattan-bound service at High Street. To get to stops in lower Manhattan served by the A or C, take the 2, 3, or 4 to a nearby stop, or take an A or C to West 4th and catch a Brooklyn bound train back to the skipped stop. In a sort of subway do-si-do, Brooklyn bound F trains will be re-routed over the A and C line from West 4th to Jay Street, so twice as much Brooklyn bound service at High Street but none at York Street. To get to York from Manhattan either take an F to Jay and switch to a Manhattan bound F back to York, or take a Brooklyn bound A, c. or F to High Street and walk down the hill.
In a reversal of last week’s pattern, there will be Manhattan bound service on the R and (midnight through the wee hours) N service at Court and Jay, but no Brooklyn bound service at these stations, as all trains will be sent over the Manhattan Bridge. If you happen to be on one of these diverted trains, you can get off at DeKalb Avenue (the first stop in Brooklyn) and change to a Manhattan bound train that will take you back to Court or Jay.
The following week (Monday the 13th through Friday the 17th) from 10:00 p.m. to 5:00 a.m. there will be no 2 or 3 service to or from Brooklyn, so no service at Clark Street or on the 2-3 platform at Borough Hall. Use the A, C, R (N late at night), 4 or 5 as an option.
