With about 600,000 new residents expected to join the state by 2040 — the equivalent of adding another Boston-sized city — traffic congestion will likely get worse unless action is taken, the head of a state transportation commission said Wednesday.
“With respect to the highway system in particular, the commission expects that keeping congestion at reasonable levels will rely more on the efforts to manage the demand for existing capacity than increasing its supply,” Steve Kadish, who chaired Gov. Charlie Baker’s Commission on the Future of Transportation, said during a Transportation for Massachusetts event that delved into the panel’s findings.
“While selective highway improvements will be necessary, the era of major highway construction is long gone,” Kadish said. “Congestion mitigation and better transit must go hand-in-hand, because neither building nor managing congestion by itself will work.”
