on September 2, 1963, its southern terminus (and that of today's M2 and M3) was moved to 8th Street west of University Place, then turning on there to 9th Street towards Fifth Avenue. Next, on November 10, 1963 (the same day the NYCO's 5 was discontinued), the southern terminus of the FACCo's 5 was moved to Houston Street and West Broadway, and its route south of 8th Street extended to Broadway southbound and Sixth Avenue northbound (M2 and M3's southern terminus was moved further east to 8th Street and Fourth Avenue in the vicinity of Cooper Square as part of the same service change). The rest of the 5's northbound route below 57th Street was shifted to Sixth Avenue on January 14, 1966 following Fifth Avenue's conversion to one-way southbound. Then, its northern terminus was extended to 178th Street – George Washington Bridge Bus Station on January 10, 1971. Closures of Broadway in the Theater District south of 47th Street and around Herald Square in 2009 resulted in major changes to the M6's southbound service, with the northern half of the route shifting to Seventh Avenue before returning to Broadway in the vicinity of Union Square. On July 13, 2009, southbound M6 service was rerouted to run across 23rd Street instead of 14th Street to provide more consistent service. On June 27, 2010, due to budget problems, the M6 was discontinued and the M5 was extended to South Ferry via Broadway to replace former M1 and M6 service south of Houston Street. In January 2016, it was proposed to split the M5 into two routes. The uptown section would continue to operate as the M5, running between Washington Heights and West 37th Street in Midtown. The downtown section would be the M55, a new route between Midtown and South Ferry. In July, in response to public comments, the proposal was modified so the routes could have a 13-block overlap in Midtown. Under the modified proposal, the M5 would run between Washington Heights and West 31st Street near Penn Station and Herald Square; the M55 would run between West 44th Street, two blocks north of Bryant Park, and South Ferry, starting on January 8, 2017. The new route would provide 88% of M5 customers to have reliable service without transferring, since many customers from both ends wanted to retain service to Midtown (the area between 34th Street and 59th Street).
