In April 2019, the busway was added back to the plan. SBS was later pushed back to July 1, 2019. However, due to a lawsuit, the busway was not implemented as scheduled, and after another delay that August, went into effect on October 3, 2019. The busway was so successful on its first day that M14 buses had to be slowed down in order to keep from running ahead of their posted schedules.In late 2019, the M14A/D SBS were the launch routes for the MTA's new New Flyer Xcelsior XE60 buses.
