Construction of the the Green Line extension starts tomorrow in Somerville, breaking ground on the first phase of the long-awaited project.


While at a press conference today at Logan International Airport, State Transportation Secretary Richard Davey said he is "confident" about the first portion of the project, but that he is "not sure" how the project will be funded down the road.


"Well, certainly, with phase one we’re very confident. Phase one to go to Union Square and then north to Washington Street. We do have the funds in our capital bond program to pay for phase one. I’ve been clear that if we don’t solve our transportation finance crisis I’m not sure how we’re going to pay for it further north," Davey said.

"If we’re able to solve the T’s fiscal crisis, in fact our entire transportation crisis, we’re very bullish that the federal government will contribute upwards of a half a billion dollars to the Green Line extension. It’s not an insignificant number," he said.


Construction will begin tomorrow at 1:30 p.m. at the Medford Street railroad bridge in Somerville.
