"Honolulu’s rail transit project could now cost $200 million more to build — bringing its projected shortfall to more than $1 billion — and take about a year longer to complete," according to the Honolulu Star-Advertiser.

The news comes via a letter sent by Don Horner, the Honolulu Authority for Rapid Transportation's new board chairman, and HART Executive Director Dan Grabauskas. The letter also shared the bad news of the projects delay—pushed back to 2021 instead of the first quarter of 2020. The article also lists other changes and challenges described by the letter.

The letter arrives, according to the article, "as the City Council considers its final vote on a five-year rail tax extension to help the project climb out of its current budget hole." The 800-pound gorilla in the room: "The letter makes clear that the Council still lacks a lot of the latest facts on the project, ahead of that vote later this year."
