New York’s Metropolitan Transportation Authority announced plans to begin construction on the East Harlem extension of the Q Line, also known as the Second Avenue Subway, in September.

As Ramsey Khalifeh explains in Gothamist, “The nearly $2 billion deal covers the bulk of the work for the extension, which aims to add three new stations on the Q line that transit officials said would one day serve 110,000 daily riders.”

The MTA stopped work on the East Harlem extension in 1975, when the city was in the throes of a financial crisis. Now, the $7.7 billion project will include a new tunnel, the rehabilitation of an existing tunnel, and three new stations. “The awarded contract will also include designing and building a “state-of-the-art” tunnel boring machine that both excavates the earth in front of it and simultaneously installs concrete tunnel lining behind. The boring machine is expected to go into the ground in 2027.”
