The Honolulu rail project, officially known as Skyline, is facing yet another major hurdle. Hitachi Rail Honolulu Joint Venture (HRH), the primary contractor responsible for the design, build, operate, and maintain (DBOM) aspects of the project, has initiated legal action against the Honolulu Authority for Rapid Transportation (HART). The lawsuit, filed on November 17, 2025, in Oahu’s First Circuit Court, seeks approximately $320 million in damages, accusing HART of “gross mismanagement” and alleging that the agency's actions have led to substantial project delays and cost overruns.

The complaint details the extensive delays, which have plagued the project for “six years and counting,” according to the original reporting from Hawaii Free Press. The Skyline project, envisioned as a vital component of Honolulu's public transportation infrastructure, already experienced considerable setbacks. The first segment of the project opened in June 2024, after many delays, as reported by Hawaii Tribune-Herald. These delays have not only impacted the timeline but have also significantly increased costs, placing a heavy burden on private companies like HRH and the public purse.

The lawsuit's implications extend beyond the immediate financial claims. The prolonged disputes over the contract could discourage future investments in local infrastructure projects and potentially impact other ongoing construction ventures in Hawaii. Construction Dive also reported on the lawsuit. For local construction firms, the uncertainty surrounding project completion and payment schedules can pose significant challenges, affecting their cash flow and ability to bid on new projects. Investors, too, may become wary of the risks associated with public-private partnerships if disputes between contractors and government entities become commonplace.

This legal battle could set a precedent for how future infrastructure projects are managed in Hawaii. It underscores the importance of clear contractual terms, effective project oversight, and transparency in financial dealings. As the lawsuit progresses, it will be crucial for the local business community to monitor developments closely and assess the potential impact on their operations and investment strategies. The outcome could reshape the landscape for businesses involved in infrastructure and development across the Hawaiian Islands, potentially influencing future projects and financial decisions.
