Plans move ahead for Second Avenue Subway Phase Two in Harlem

It's round two for the Second Avenue Subway in the heart of Harlem.

When will it open? How will it be funded? What are the specific designs?

Phase Two would add three new stations at 106th and 116th Streets on Second Avenue and connect to the Lexington Line at 125th Street. Some of the tunneling has already been done during previous work on the project.

MTA Capital Construction officials have been making presentations to community boards, neighbors, riders and business owners along Second Avenue and 125th Street in Harlem and East Harlem.

Manhattan Community Board 10 Transportation Chairperson Raquel Vazquez looks forward to the project and wants to make sure small businesses are a part of the planning process.

By July, MTA officials say they expect to have completed the required Environmental Impact Review period. Design will get underway and there could be some construction by the end of 2019.

A document filed with the Federal Transit Administration says revenue service could begin between 2027 and 2029.

Significant federal funding for this project is expected to be available in 2020. More than a billion and a half dollars has been included in the current MTA Capital Plan for big projects.

The project has been a priority for the MTA since the opening of Phase One on the East Side in January 2017. After decades of starts and stops, construction on that portion had a ground-breaking in 2007.

There will be significant utility and road work required between the stations at 106th and 116th Streets. Deep drilling will happen along Second Avenue from 116th Street to meet up and create the station at 125th Street. Underground train storage tracks will stretch past that station to Lennox Avenue.

Ventilation facilties will be built near the new stations. Those specific locations are still being considered. MTA officials say the buildings along 125th Street will not be "blank walls." The vent and power facilities can also include retail and commercial space.

MTA Chief Development Officer Janno Lieber says lessons were learned from Phase One about community outreach and involvement.

A Neighborhood Center with information about the project opened in 2017 on 125th Street at Park Avenue.
