MTA completes tunneling for first phase of subway project
advertisement
Earlier this week, the New York Metropolitan Transportation Authority (MTA) completed tunneling for the first phase of the Second Avenue Subway in New York City when a tunnel-boring machine broke into the existing tunnel and reached the Lexington Avenue-63rd Street station.
The completion of the tunneling marks “a major milestone” for the $4.5 billion project, which will establish service from 96th to 63rd streets as an extension of the Q train, MTA officials said in a prepared statement.
The 485-ton, 450-foot long tunnel-boring machine mined a total of 7,789 linear feet, averaging 60 linear feet a day. The average depth of the tunnel is 70 feet.
Phase I of the Second Avenue Subway will serve more than 200,000 riders daily, reducing crowding on the Lexington Avenue Line and restoring a transit link to a neighborhood that lost the Second Avenue elevated line in the 1940s, MTA officials said.
