overlapped between Penn Station and Columbus Circle. Riders transferring between the M10 and the M20 were given an additional free transfer. Since the M10 no longer served Abingdon Square, westbound M14 service was increased during the afternoon. Due to a budget crisis, M10 buses' southern terminus was truncated to Columbus Circle on June 27, 2010. On the same day, the M20 was extended to South Ferry, replacing the section of the M9 south of City Hall. The truncation, which saved $1.1 million annually, resulted in a significant drop in ridership on the M10, with riders instead using the M7, the M20, and the subway. M20 ridership increased with the truncation of M10 service and its extension to South Ferry. On April 3, 2011, however, M10 service was extended by two blocks to 57th Street, with the final southbound stop at 58th Street and Broadway and the first northbound stop at 57th Street and Eighth Avenue.
