“Green Line project could be priciest effort for MBTA” (Boston Globe)
“Based on a $3 billion overall price tag, the 4.7-mile project would cost $642 million per mile. That would be significantly higher than the reported costs of four other major extension projects, a Globe analysis found.”
“The Green Line extension’s price tag is also high when compared with other similar projects around the nation, according to a recent analysis by the Arup Group, a consulting firm the T recently retained to help find ways to reduce the project’s cost.”
