On March 5, 1944, the line west of Bridge–Jay Streets was closed coincident with the end of elevated service over the Brooklyn Bridge. On January 21, 1953, the Grand Avenue station was closed so that it could be torn down and therefore complete the demolition of the BMT Lexington Avenue Line. The rest of the line from Broadway to Jay Street closed on October 4, 1969 and was demolished soon after, ending the MJ service. A free transfer to the B54 bus replaced the MJ, and service was increased on that bus. The free transfer at Jay Street was also replaced with a bus transfer.
