Honolulu Rail Transit Route Map, Status, & Cost Update 2026
The Honolulu Rail Transit project is an active 18.9 mi automated rapid transit network stretching from East Kapolei to Kakaʻako's Civic Center, establishing the primary honolulu rail transit line across Oʻahu. Developed by HART in coordination with the FTA through a joint federal-local funding model, the system links vital urban centers including Pearl City, Honolulu International Airport, and Downtown Honolulu. Official plans dictate a fully elevated right-of-way alignment designed after thorough environmental review processes to bypass severe arterial traffic congestion. Operating four-car steel-wheel automated light metro trains, the transit system aims to streamline regional mobility across major residential and commercial districts. Civil engineering progress continues across final urban segments toward the target completion date. Strategic route map documentation and updated environmental disclosures highlight ongoing structural work, utility relocation, and station delivery along this essential Pacific infrastructure corridor for regional public transit.
Project information is compiled from official agency documents, federal records, environmental reviews, and verified public announcements.
