The MTA is looking to move ahead with plans for the next phase of the Second Avenue subway. MTA Officials said that they have formally asked the federal government to cover a third of the project’s massive cost which would rely on money coming from Washington. MTA officials said Monday they hope to shave about a billion dollars from the project’s projected $6 billion cost. The work would extend the Second Avenue line north from 96th Street, where it now ends, to 125th Street and Lexington Avenue, with new stations at 106th, 116th, and 125th Streets. Sections of the line, from 110th to 120th Streets, were built in the 1970s, but the work was halted in 1975 because of the city’s financial crisis. Phase One of the Second Avenue line, from 63rd to 96th Streets, opened in 2017 at a cost of nearly $4.5 billion. The goal is for Phase Two to be completed in 10 years.
