MTA figures out how to save $500M on Second Ave. Subway by using 1970s tunnel

The tunnel stretches from 110th St. to 120th St. in East Harlem — and Janno Lieber, head of MTA construction, said he and his colleagues recently discovered they could build a planned 116th St. station in the underground space, which was not intended to house a stop when it was first dug up decades ago.
