The tunnels were built with TBMs. The actual stations were cut and cover.

You can't really build stations any other way. New York is way too expensive to buy property alongside the road as an access shaft, and in any case you need to be able to access both tracks from any given entrance. So either you have an island platform directly under the middle of the street or two side platforms on either side, both of which would need a connecting passageway the width of the street, from street to platform.
Even with the tunnel boring they did on the Upper East Side of NYC for the 2nd Ave Subway, half the avenue was dedicated to construction entrances and other above-ground activities. Ultimately, may stores did go out of business. My point is, tunnel boring is also quite disruptive to what happens at the street level.
