HONOLULU (AP) - Honolulu Mayor Kirk Caldwell has been encouraging state lawmakers to extend a tax to keep the city's rail project progressing but says he can't provide more details on the project's final price tag.
The city has internal cost projections for the project but Caldwell says he can't share them because the work hasn't been put out to bid.
He says disclosing the figures would tarnish the process.
The Honolulu Star-Advertiser reports Oahu's .5 percent general excise tax surcharge supporting the rail project is due to end it 2022.
Rail advocates want it extended in perpetuity. They say the revenue is needed to pay for work on final bids opened next year.
Some legislators say the lack of details on the projects final costs is complicating their decision.
