The estimated costs for Honolulu's planned elevated rail have climbed to between $4.28 billion and $5.34 billion in today's dollars depending on the route, according to a new study released this morning.

Those costs, which include financing charges, were not included in an executive summary of the report released by the city on Thursday. Lower project cost figures released by the city Thursday excluded finance costs.

Those costs are up from a prior projected cost of $3.7 billion in 2006 dollars for a 20-mile elevated route running through Salt Lake. According to a draft environmental impact statement released today, the cost of the Salt Lake route now is projected to cost $4.28 billion.

A combined Salt Lake and Honolulu International Airport route is expected to cost $5.34 billion. The inflation-adjusted costs of the two routes are now $5.28 billion and $6.48 billion, respectively.
