Beneath Second Avenue on Manhattan�s Upper East Side, a 485-ton monster is chewing its way through bedrock, mining tunnels for New York City�s first new subway line in 50 years.
When completed in 2016, the Second Avenue line will run from 96th to 63rd Streets, where it will hook up with the existing 63rd Street and Broadway lines. Three new stations will be built at 96th, 86th and 72nd Streets along with new entrances to the existing Lexington Avenue/63rd Street Station.
