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).
The rail system, officially named Skyline, opened to the public on June 30, 2023.

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 2

Airport Guideway and Stations (AGS) | Aloha Stadium to Middle Street Transit Center

Includes 5.2 miles of elevated guideway and four stations located at Pearl Harbor, Daniel K. Inouye International Airport, Lagoon Drive, and Middle Street.
Train testing is underway. A trial run is expected to begin in July 2025, followed by safety certification in partnership with City, State, and federal agencies.
Once ALL requirements are met, Segment 2 will be transferred to DTS for passenger service. The anticipated opening date is October 1, 2025, as announced by Mayor Blangiardi.

Important Safety Reminder:
Although stations in this segment may appear complete, they remain active work zones. The third rail, which powers the trains, is energized and carries 750 volts of electricity, posing a fatal risk if touched.

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.
Guideway construction is anticipated to begin in summer 2025, starting with shaft construction in Iwilei.
Geotechnical boring is currently underway.
Downtown utilities is nearly complete, clearing the way for column construction.
Dillingham utility relocation is expected to be completed mid-2026.

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.

The “HART Dillingham Construction Sequencing” video rendering is a visual guide to the planned utility relocation, guideway, and station construction along the Dillingham Corridor. While the video is representational and not an exact depiction of the work, it provides a general overview of the expected construction sequencing through project completion in March 2031.
