Honolulu’s rail project is now expected to cost taxpayers $6.9 billion, about $1.6 billion more than the original price tag for the 20-mile rail line.

Colleen Hanabusa, chairwoman of the Honolulu Authority for Rapid Transportation Board, shared a confidential document with the Honolulu Star-Advertiser on Thursday detailing budget estimates as of March 1.

The document shows the estimated cost of building the rail line shot up by nearly $350 million from last October to March.

The increases are due to updated estimates of the cost of building the final 10 miles of the line from Honolulu International Airport to Ala Moana Shopping Center.

Hanabusa said in a phone interview Friday that the need to relocated utility lines underground helped drive up the costs. She expects the price tag of the rail project to continue to rise.

The final cost won’t be known until bids for the final contracts are opened.
