2nd Avenue Subway: See rare photos of New York subway construction

New York City’s newest subway line reportedly is on track to open in December 2016

New York City has the most extensive subway system in the world, running 24 hours a day, seven days a week. And it's about to grow.

We will try to avoid the question of quality of the New York subway – if you want to hear a New Yorker complain, ask them about the MTA, the body that operates the city’s public transportation – but the quantity is soon to go up.

The first phase of the 2nd Avenue subway line is set to open in December 2016 – surprisingly on time – to the tune of some $4.5 billion. The line’s first phase is about 82 per cent complete and reporters were given a rare underground tour of the subway construction.
