extra service was discontinued after completion of tunnel construction on April 27, 2020. Weekday evening service after 9:15 p.m. was also indefinitely cut back from Forest Hills to Essex Street to accommodate maintenance work for the installation of communications-based train control on the Queens Boulevard Line, Eighth Avenue Line, and Sixth Avenue Line. MJ service On March 5, 1944, 11 trains stopped running over the Brooklyn Bridge, instead ending at Bridge–Jay Streets on the Brooklyn side, and all 11 trains terminated there (with a free transfer to the IND trains at Jay Street–Borough Hall). In 1967, when the Chrystie Street Connection opened, the label MJ was assigned to the 11 service. The western half of the Myrtle Avenue Line closed on October 4, 1969, ending MJ service, which was replaced with a free transfer to the B54 bus. Several days before the scheduled closing date, some supports for the elevated structure were hit by a truck, temporarily suspending service. Timber reinforcement was applied to damaged members, allowing service to resume operation until the scheduled closing date.
