As Labor Day weekend approaches, the MTA is informing riders this week about planned service changes across the subway system.

Starting Monday, August 26, nighttime service on the 2 Line between the Third Avenue-149th Street stop in the Bronx and 135th Street in Manhattan will be suspended from 9:30 p.m. to 5:00 a.m. daily through Friday. Free shuttle buses will be available while the MTA works on track replacements.

Due to track work, trains on the 4 line heading toward New Lots Avenue will also run from the Atlantic Avenue-Barclays Center station to the Crown Heights-Utica Avenue station overnight Monday through Friday, stopping only at Franklin Avenue. Service on the 3 line will be suspended during this time, with trains 2 and 4 stopping on the 3 line.

For anyone looking to get around the city this holiday weekend, the 2 train line between Third Avenue-149th Street in the Bronx and 96th Street in Manhattan will not run from 11:30 p.m. Friday to 5 a.m. Monday. However, free shuttle buses will once again be available.

Line 3 will also be suspended over the weekend; trains 2 and 4 will stop in Brooklyn.

Meanwhile, G train service between Bedford-Nostrand Avenue and Church Avenue stations in Brooklyn is expected to resume at 5 a.m. Tuesday after the third phase of repairs is completed during the line’s summer break. The work is designed to improve the G train’s reliability by upgrading signals, switches and tracks.
