M5 would continue to have limited-stop service during the daytime, while the M55 would operate local at all times. Other ideas to improve reliability, which included restoring the M5 and M6 to their pre-2010 services and converting the M5 into a Select Bus Service route, were rejected. A three-legged transfer was provided to M5 and M55 customers along Fifth and Sixth Avenues. The split M5 and M55 services began on January 8, 2017.
