Under a fare hike proposal announced Monday by the Massachusetts Bay Transportation Authority, riders on buses, subways and trains will see an average 6.3 percent fare increase.
Boston area transit officials say they are committed to connecting two city subway lines, a move advocates say will benefit the entire region.
The Massachusetts Bay Transportation Authority on Monday made a fresh commitment to building the Red Line-Blue Line connector.
The actual construction that would extend the Blue Line tunnel 1,500 feet under Cambridge Street to the Charles/MGH Station on the Red Line could be years away.
But the decision by the MBTA to prioritize the project was praised by transportation advocates, who say such a link would connect lower-income residents to jobs and medical resources, spur development, ease access to Logan International Airport, and reduce road traffic.
The T released a study last fall that put the cost of the rail tunnel at $200 million to $350 million.
