In many areas of the city, especially Downtown Brooklyn/Lower Manhattan, some subway lines are extremely close together as a result of their origins. So, an idea that I had was, in a consolidated system (aka the )--what if, some sections of some lines that are too close to another line were terminated in order to focus on building projects in outer areas, or streets that are not so close to each other? E.g. in Lower Manhattan btwn Broad and Kenmare the (), (), and are all pretty close to each other. So, for example, what if the rerouted from Lower Manhattan and went northbound on 2 Av instead, or southbound via Chrystie and Park Row like the proposed would? (They could also be part of the 's route, idk). Ofc, I understand that sometimes bc of population density it is good for multiple routes to be part of the same area (e.g. and , and proposed Northern Blvd line) though I think that there is an excess in some areas of Lower Manhattan in particular, esp since subway service there is typically just a block away from another.
