The Vox article [1] specifically cites depth as a contributor to the Second Avenue Line's increased cost:
"the majority of the Second Avenue subway’s price tag actually comes from the stations rather than the tunnels. The line is being built unusually deep for a subway tunnel, which doesn’t do much to change the basic logistics of boring a tunnel, but does make excavation of station caverns unusually difficult."
