Construction Overview
The Honolulu Rail Transit Project, excluding park-and-ride facilities, is currently divided into three construction segments.
Operating Segments
Segment 1
West Side Stations and Guideway (WSSG) | East Kapolei to Aloha Stadium
- Includes the first nine stations and 10.75 miles of fully completed guideway:
Kaualakaʻi (East Kapolei), Keoneʻae (UH-West Oʻahu), Honouliuli (Hoʻopili), Hōʻaeʻae (West Loch), Pouhala (Waipahu Transit Center), Hālaulani (Leeward Community College), Waiawa (Pearl Highlands), Kalauao (Pearlridge), and Hālawa (Aloha Stadium). - On June 9, 2023, HART transferred 10.75 miles of guideway, nine stations, the 43-acre Rail Operations Center, and twelve four-car trains to the City and County of Honolulu’s Department of Transportation Services (DTS).
- Skyline’s Segment 1 opened to the public on June 30, 2023.
Segment 2
Airport Guideway and Stations (AGS) | Aloha Stadium to Middle Street Transit Center
- Includes four stations and 5.2 miles of fully completed guideway:
Pearl Harbor (Makalapa), Daniel K. Inouye International Airport (Lelepaua), Lagoon Drive (Āhua), and Middle Street (Kahauiki). - On October 1, 2025, HART transferred 5.2 miles of guideway, four stations, and 7 four-car trains to DTS.

For information on fares, schedules, safety, and operations, visit the City’s Department of Transportation Services or call the Skyline Hotline at 808-848-5555.
Segment 3
City Center | Middle Street Transit Center to Civic Center
- Includes 3 miles of elevated guideway and six stations at Kalihi, Honolulu Community College-Kapālama, Iwilei, Chinatown, Downtown, and Civic Center.
- Drilling of the first column shaft along Nimitz Highway began on October 16, 2025
- Column construction expected to begin late 2025.
- Downtown utilities is nearly complete, clearing the way for column construction.
- Dillingham utility relocation is expected to be completed late 2026.
- Neighborhood Station Design Workshops are underway for preliminary station designs in this segment.
Construction of Segment 3 is anticipated to be completed in 2030, with transfer to DTS by 2031.
City Center Utilities Relocation involved moving critical infrastructure including storm drains, sewer lines, water mains, gas and fuel lines, electrical systems, and communications lines along with roadway improvements. These relocations are necessary to support the construction of columns, elevated guideway and stations.

HART 2022 Recovery Plan
Construction Simulation: Dillingham Boulevard
HART’s 2022 Recovery Plan proposed an amendment to the original Full Funding Grant Agreement (FFGA), a contract between the City and County of Honolulu and the Federal Transit Administration (FTA) executed in 2012. The initial FFGA provided $1.55 billion in federal funding and outlined the project scope, 20 miles and 21 stations from East Kapolei to Ala Moana. However, when the project encountered challenges, HART submitted a 2022 Recovery Plan to the FTA, which proposed to truncate the project scope from the original 20 miles and 21 stations to 18.9 miles and 19 stations from the East Kapolei Station to the Civic Center Station; the FTA accepted this plan in September 2022.
The 2022 Recovery Plan also proposed the deferral of the Pearl Highlands Parking Garage. The scope change required an amendment to the Full Funding Grant Agreement (FFGA), which was necessary to maintain the funding needed to complete the remainder of the project.
Throughout 2023, HART collaborated with the FTA on amending the FFGA document, requiring approvals from various entities such as the U.S. Department of Transportation, the U.S. Congress, Governor’s Office, HART Board, City Council Committee on Budget, and Full City Council. By February 2024, the FFGA was executed, enabling the release of $125 million of the remaining $744 million federal funds, marking a significant milestone — the first appropriation from the FFGA in almost ten years.
