NYC Second Avenue Subway

From Curbed - nine U.S. transportation projects to watch in 2017:

"The first major MTA subway expansion in 50 years, the oft-delayed Second Avenue Subway line is set to start the new year off right with a January 1, 2017 opening. Originally discussed in the 1910s and subsequently delayed by the Great Depression and a lack of post-war funding, the Second Avenue Subway’s first bout of construction started in 1972 but was halted again in 1975 due to a fiscal crisis in the city.

Work on the line restarted in 2007 and the MTA promised transit riders the project’s first phase would be open by 2017. Now, it looks like the line will make its deadline, with full service of the $4.5 billion line beginning on January 9. Phase two—which would run from 96th to 125th streets—won’t begin until at least 2019 and could cost a staggering $6 billion to finish. Still, this moment can’t be overstated.

As Curbed NY writes, “Nearly a century after the idea of a Second Avenue line was first proposed, and a decade after construction actually began, the Second Avenue subway is this close to becoming a reality.” Head over here for more info."
