The Second Avenue Subway is currently set to expand from its phase 1 completion, which wrapped up in January 2017 with the opening of the 72nd, 86th, and 96th Street stations. The decades-old project, which was originally proposed in 1920, moved into the next stage of the federal funding process earlier this year, that would make way for the extension of the line up to 125th Street in East Harlem. Three new stations would be built along this route. 

Now, according to documents released by the MTA this week titled the MTA’s 2025-2044 20-Year Needs Assessment, the Authority will consider extending the Second Avenue Subway even further. The line would move westbound along 125th Street, adding two to four new subway stations. Listed possibilities include the route ending at Broadway and 125th Street, turning north below Broadway to a connection at 137th Street, turning north under Riverside Drive to a connection at 137th Street, or turning north under St. Nicholas Avenue and continuing along the 8th Avenue line north of 135th Street. 

This, however, is just one of 23 proposals that MTA officials will evaluate before choosing a select few to receive funding in an effort to upgrade New York City’s transit system.
