Metro reports that some East Boston state lawmakers and residents are unhappy about the MassDOT project involving the AET conversion of the Sumner Tunnel toll plaza. “Redesigning the . . . toll plaza to streamline traffic into the city has actually had the opposite effect of congesting traffic further into the city and causing much more pollution,” a state senator tells the newspaper. MassDOT has made a traffic pattern change in an effort to alleviate congestion.
