Seattle Can Learn From Boston's Big Dig

"Now in its final stages, [Boston's Big Dig] has been saddled with allegations of mismanagement, misleading the public about rising costs and a host of other ills. At the center of the debate are official cost estimates that went from $2.6 billion in 1983 to $14.6 billion today. The heart of the Big Dig may sound familiar: replacing an elevated highway through the middle of downtown with a tunnel — a project similar to plans to deal with the aging Alaskan Way Viaduct in Seattle."
