The route is redundant; seventh avenue is already covered by the M7, M5, and the M104 (up to 41st street) and Broadway doesn't need bus service because there are so many viable options in the area (M1, M2, M3, M5, and the N and R). On top of that it is being converted to a pedestrian plaza so bus service would end up being inefficient. Again that's why I said it would be better to bring back the old M1 to south ferry
