A separate November 13–16 plan replaces part of the J route with free shuttle buses.
From November 10–13, 2026, J service in Bushwick and Williamsburg, Brooklyn, is scheduled to make local stops both ways from Myrtle Av to Marcy Av, 9:30 AM–3 PM.
Brooklyn Community Board 4 links the weekday changes and weekend disruption to the Marcy Av switch replacement. The work spans selected dates in October and November.
During the November 13–16 service period, J trains are scheduled to run only between Myrtle Av and Jamaica Center/Parsons Archer. Free shuttle buses replace J service from Myrtle Av to Delancey St/Essex St.
The M is scheduled to run in two sections: Metropolitan Av to Myrtle/Wyckoff Avs, and Myrtle/Wyckoff Avs to Myrtle Av-Broadway. The notice gives no exact weekend start or end times.
