In contrast the 2nd Avenue Subway will be built using a TBM, the world standard nowadays. But it will use just one TBM that will go south from 96th Street to 63rd Street to carve out one tube and backtrack up to 96th Street to complete the second tube. The analogy I make is "typing out War and Peace...one hand at a time."
In the meantime, business close or barely skim the bottom. The city as whole pensively waits to see if this thing will actually get done and if this is the way subway construction will be from now on.
