The M train will resume regular service on April 30, running from Forest Hills-71 Avenue, Queens to Middle Village-Metropolitan Avenue in Queens, via Sixth Avenue in Manhattan.
On July 1, 2017, the reconstruction began, and was split into two phases:
Phase 1 (July 1 to September 2): M trains were diverted to Broadway Junction via the J line after Myrtle Avenue, while shuttle buses ran along three routes to replace the M to Metropolitan Avenue:
- Between Myrtle Avenue and Fresh Pond Road, making all M stops throughout its run.
- Between Between Myrtle Avenue and Metropolitan Avenue, skipping Fresh Pond Road.
- Between Flushing Avenue and Metropolitan Avenue, stopping at Flushing and Wyckoff Avenues, connecting with the L train at Jefferson Street.
Phase 2 (September 2 to April 30, 2018): M trains were still diverted to Broadway Junction after Myrtle Avenue, while a shuttle train service operated between Metropolitan Avenue and Myrtle-Wyckoff Avenues, connecting with the L train for a connection to the mainline M at Broadway Junction, and a shuttle bus making stops at Knickerbocker and Central Avenues (which were still closed), to Myrtle Avenue for the J, M and Z trains.
