Abingdon Square Park and Bleecker Park, Hudson Street feeds into Eighth Avenue, which the M20 follows into Midtown. At West 66th Street, the M20 turns west, then turns south on Broadway, terminating at West 63rd Street. History Streetcar service The Eighth Avenue Railroad opened the line from the north end of the trackage shared with the Sixth Avenue Railroad's Sixth Avenue Line at Canal Street and Varick Street along Canal Street, Hudson Street, and Eighth Avenue to 51st Street on August 30, 1852. It was eventually extended north to 159th Street, with a branch along Macomb's Lane to 154th Street, and another branch to the south along Canal Street east to Broadway. Bus service Buses were substituted for streetcars by the Eighth Avenue Coach Corporation in March 1936, a company owned by Fifth Avenue Coach Company. The New York City Omnibus Corporation took over operations of the route, known as Route 10, in 1951, and in 1956 it was renamed Fifth Avenue Coach Lines; the Manhattan and Bronx Surface Transit Operating Authority replaced it in 1962.

Initially, New York City Omnibus planned to reroute northbound Route 8 buses along Seventh Avenue to Hudson Street and Eighth Avenue for its entire route between 59th Street and Canal Street, and reroute a portion of southbound service from Times Square's east side to the west side starting at 47th Street on June 12, 1954. Instead, at the request of T. T. Wiley, the Traffic Commissioner, Route 8 was discontinued and combined with Route 10 on June 13. This change eliminated a u-turn at Central Park South and Seventh Avenue. In 1962, when the Surface Company bought the route they put one bus service for the entire length. This was given the route number 10, which then became bus M10. In Fiscal Year 1963, the route was modified due to
