President Obama has included $100 million in funding for the MBTA’s Green Line extension to five new stops in Somerville and one in Medford in his budget proposal for the upcoming fiscal year. The proposal paves the way for agreement with the federal government for greater support for the project during the next several years, according to a press release from the state Department of Transportation. Earlier this year, Governor Deval Patrick’s administration requested that the federal government fund 50 percent of the $1.428 billion project, according to the state. The Green Line project will build a new Lechmere Station in Cambridge along with the six new stops. It was one of eight new transit projects included in the president’s budget proposal, according to a statement from US Transportation Secretary Anthony Foxx’s office.
