Sprawl and traffic congestion are high on the public agenda, even in the bucolic state of Maine where voters, in the past, have rejected plans to widen the Maine Turnpike. But as traffic jams grow worse each summer, some say the state should widen the turnpike from four lanes to six. The turnpike authority is expected to make an announcement about this plan in the near future. Still, many in Maine are against more lanes for the toll expressway and argue that before putting down more pavement, the state should try some transportation alternatives; like bringing back the passenger rail service to Boston which was cut off thirty years ago. John Rudolph has our report.
