The 20-mile elevated rail line on the Hawaiian island of Oahu was originally projected to cost $4.6 billion. Currently under construction, and two years behind schedule, the rail line may now cost up to $7.1 billion. Hawaii state officials believe the project must be completed, regardless of the potential for multi-billion dollar cost overruns often associated with projects of this magnitude, much like Boston’s Big Dig or California’s high-speed rail.
