The feds have given the green light for the MTA’s plan to build four new Penn Station-bound Metro-North rail stations in the Bronx, Gov. Andrew Cuomo announced today.

The project, known as “Penn Station Access,” will be completed by 2025, Cuomo said during a press conference with Bronx pols. The federal thumbs up means officials can now conduct an environmental review of the plan, which has been years in the making.

“This is happening. It’s happening and it’s happening now,” Cuomo said. “The RFP goes out today, we do an environmental assessment, we’re going to aware the project next year, it’s going to be completed in four years, 2025.”

“It is going to be transformative for these communities,” he added.

The four new stations will be located along an existing Amtrak route in the east Bronx communities of Hunts Point, Parkchester, Morris Park and Co-Op City — connecting the busy New Haven Line to Penn Station.

New Haven-bound trains currently go in and out of Grand Central on Manhattan’s east side, and typically skip most local stops along the way.

The MTA plans to accept public comments on the plan for 45 days, the governor’s office said in a release.

“The most cost-effective capital projects are those that squeeze more mass transit service out of existing infrastructure, rather than always building something new from scratch,” MTA construction chief Janno Lieber said in a statement.

“By rebuilding this under-utilized Amtrak rail line to accommodate new Metro-North service, this project will give East Bronx residents better access to jobs, education and a full range of opportunities.”
