The Second Ave line is a disaster like you'd expect in any multi-billion-dollar infrastructure in the US, but it's not fair to call it "100 years in the making"

The Second Ave line is a disaster like you'd expect in any multi-billion-dollar infrastructure in the US, but it's not fair to call it "100 years in the making". It was proposed and planned 100 years ago, but cancelled. Then they worked on it for three years in the 70s, but the recent work wasn't begun until 2007. Again, still a disaster, but an order of magnitude less than how "100 years in the making" makes it sound. They weren't working on it steadily since 1919 :)
