subway service was restored one month ahead of schedule. The project cost $130 million, including replacing the tracks' support structure, signal systems and other equipment. From July 23, 2001 to February 22, 2004, work on the Manhattan Bridge subway tracks resulted in a midday extension back to Ninth Avenue, as well as an extension of the times that the rush hour service was provided to 10 p.m. This change preserved service between the West End Line and Chinatown for passengers that would have taken the to Grand Street. When full Manhattan Bridge service was restored, midday M service was cut back to Chambers Street. Neighborhood leaders in Chinatown were angered by the decision to terminate midday at Ninth Avenue, instead of running it to Bay Parkway. A spokesman for New York City Transit stated that it was easier to terminate trains at Ninth Avenue and that a signal upgrade project was going on further down the line. In addition, the temporary midday service to Brooklyn was lightly used, with an average of 50 to 60 riders per train during middays going to Brooklyn, and fewer than 50 riders per train during evenings going to Brooklyn. The September 11, 2001 attacks caused a temporary reduction of the M to a full-time shuttle until September 17. Then it was extended full-time over the BMT Sea Beach Line to Stillwell Avenue, replacing the , until October 28. 2007–2010 In December 2007, the MTA announced that it planned to set aside $27 million in 2008 and $60 million annually afterwards for service enhancements to help riders deal with increased fares. Extended weekday evening M service to Broad Street and weekend service to Chambers Street were part of the plan. However, on March 24, 2008, it was announced that because the agency received substantially less revenue from taxes on real estate transactions, the enhancements were reduced to $4.5 million in 2008 and $8.9 million annually afterwards. The plan to extend weekend service to Chambers Street was dropped. After several months' delay, weekday evening trains were extended to Broad Street on July 27, 2008. On November 20, 2008, in light of severe budget woes, the MTA announced a slew of potential service cuts; among them was the potential elimination of rush-hour M service which had extended beyond Chambers Street on the Nassau Street Line in Lower Manhattan to Bay Parkway on the West End Line in
