Three months later, in November 2006, Romney cut $7 million from the maintenance budget for the state's parklands (the sixth largest state park system in the country). He also cut hundreds of thousands of dollars from the budget for environmental law enforcement, efforts to promote cleaner water in communities, and hazardous waste cleanup. Transportation policy and the "Big Dig" During his campaign for governor, Romney proposed merging the Massachusetts Turnpike Authority, the government agency that managed the massive "Big Dig" project in Boston, with the Massachusetts Highway Department."Romney set to propose break on tolls: By Scott S.
