The Patriot Ledger (Quincy) reports that a proposed route for MassDOT’s South Coast Rail project could open the way for a widening of the I-93 section called the Southeast Expressway. The department “suggested last week that I-93 could be widened from eight lanes to 10, at the same time as commuter rail was expanded.” The plan calls for building two managed toll lanes in the middle of the highway’s general purpose lanes. Public-private partnership is mentioned as a possibility.
