The MTA is celebrating a Second Avenue subway milestone.
Officials from the transit agency were on hand Thursday as a subway tunnel boring machine was completing its second run from 92nd Street and Second Avenue.
It was headed for a big break through at the existing tunnel at the Lexington Avenue-63rd Street station.
This marks the completion of more than two miles of new tunnels that will provide service from 96th Street to 63rd Street as an extension of the Q train.
The first phase of the Second Avenue subway goes into service around December 2016.
The MTA says the subway eventually will serve more than 200,000 people per day. It will reduce crowding on the packed Lexington Avenue line.
The neighborhood lost its Second Avenue Elevated in 1940.
