the conversion of some two-way streets to one-way streets. Service began running north along Hudson Street and south along Seventh Avenue. On January 16, 1966, the branch of the M10 to Cortlandt Street was cut back to Vesey Street in anticipation of the demapping of several streets for the construction of the World Trade Center. Service used a terminal loop of West Broadway, Vesey Street, Church Street and Reade Street, with the terminal being located at Park Place. Previously service had traveled south along West Broadway, west on Cortlandt Street, north on the West Side Highway, east on Dey Street, and north on Church Street. The New York City Transit Authority proposed officially eliminating M10 Limited service along 145th Street and Lenox Avenue to Esplanade Gardens at 147th Street on December 30, 1986. Two southbound trips and three northbound trips had operated to this terminal, but due to passenger confusion and low ridership, this service was ended in late 1986 by the Surface Operations Department. The official change would reroute these trips to the usual northern terminal at 159th Street, and would take effect in March 1987. On April 22, 1987, the New York City Transit Authority proposed several modifications to bus routes in Lower Manhattan to serve Battery Park City to the MTA Board, including the extension of the M10. Southbound service was extended south along West Broadway, west along Vesey Street, south along West Street, west on West Thames Street, and north on Sound End Avenue to the terminal at Liberty Street. Northbound service then ran north along South End Avenue, east along Liberty Street, north on West Street, east on Harrison Street and north via Hudson Street before returning to the existing route. This change eliminated service at four stops along Church Street and Reade Street, and service along Hudson Street between West Broadway and Harrison Street, affecting fewer than 100 riders, and removed a bottleneck at Reade Street. This change was implemented at the end of 1987. In January 1999, the MTA issued a performance report on the M10 route, calling the route "extremely long and unreliable", with long headways between buses. On January 16, 2000, the M10 was split into two routes, with the northern section from Harlem to Penn Station still operating under the M10 designation, and the southern segment from Columbus Circle to Battery Park City being renamed the M20. The two routes
