Reply to comment by Wowzlul in East Side Access won't be finished by 2022, but trains to Grand Central still planned for this year by sulaymanf

Same way the 2nd Ave subway was built, you cut a tunnel and build a station. It would cost about the same per mile.

Things are pretty busy down there already. You'd need to tunnel quite deep, right? And I'm not sure that's as simple in Lower Manhattan as it was for SAS Phase 1 which was mostly solid rock. I know they're already worried about working in soft soil for SAS Phase 3/4. Lot of additional concerns about water intrusion, for one.
