The Federal Transit Administration has approved the MBTA’s new cost estimate for a scaled-down version of the Green Line extension into Somerville and Medford, a critical milestone that effectively ensures the $2.3 billion project will move forward.

The federal government had previously awarded the MBTA a $1 billion grant for the 4.7-mile light rail project, but the long-planned project was put on hold for nearly a year when cost estimates ballooned. After the MBTA scaled down the project, the FTA had to review the new estimate before the MBTA could begin spending the federal funds.

“It’s an end to a long process,” John Dalton, the new project manager for the extension, said Tuesday. “It’s a huge step in getting us ready to getting to award construction contracts in the fall.”

The project, which will add seven stops, is scheduled for completion by the end of 2021.

Andrew Brennan, the MBTA’s director of energy and environment, said the approval showed the federal government’s confidence in Dalton’s work in scaling down the project and identifying funding.
