The construction of the first segment of the Project from East Kapolei to Aloha Stadium, has been completed. On June 9, 2023, HART officially transferred 10.75 miles of rail guideway, 9 rail stations, 12 four-car trains, and the 43-acre Rail Operations Center and to the City Department of Transportation Services (DTS). This segment is now open for operations, and opened to the public on June 30, 2023.
The construction of the second segment, which includes approximately 5.2 miles from Aloha Stadium to the Middle Street-Kalihi Transit Center is progressing.
- The guideway and trackwork construction is completed.
- Construction of the 4 stations in this segment is expected to be completed in the fourth quarter of 2023.
- Core Systems equipment installation for electrical, communications, train control, and signaling has begun in this segment.
City Center Utilities Relocation work in the third segment from Middle Street-Kalihi Transit Center to the Civic Center Station in Kakaako has been continuing along Dillingham Boulevard and through the Downtown area.

HART’s 2022 Recovery Plan was submitted to FTA June 3, 2022 and accepted by the FTA, without changes, on September 30, 2022. The Recovery Plan was required by the Federal Transit Administration (FTA) to document HART’s plans for the completion of the rail project within the amount of funding that is forecast to be available. With the acceptance of the Recovery Plan, HART is now eligible to receive the remaining $744 million in federal funding under the Full Funding Grant Agreement (FFGA).
The next step will be to amend the FFGA based on the Recovery Plan scope and financial plan. Completing an amended FFGA will be the first funding-related milestone upon which the FTA will release $125 million in withheld funds.
The accepted Recovery Plan includes:
A temporary rail terminus at the Civic Center Station, located at the intersection of Halekauwila Street and South Street, and deferral of the Pearl Highlands Parking Garage. The FTA is currently conducting an environmental reevaluation of the truncated scope.
HART remains committed to completing the full scope of the project to the Ala Moana Transit Center in a subsequent phase of the project.
The destination of reaching Ala Moana is important because of the location of the Ala Moana Transit Center, the City’s largest bus transit center. More than 1,500 daily bus routes pass through Ala Moana Transit Center, where rail riders will be able to easily transfer to frequent bus service and continue their trips to Waikiki, UH, Hawaii Kai or elsewhere.
Ala Moana is also the Locally Preferred Alternative as approved by the Honolulu City Council. Despite the proposed plan to have a temporary rail terminus at the Civic Center Station, the overall goal of reaching Ala Moana Transit Center does not change.
The goal is still for the rail project to reach Ala Moana Transit Center. When the temporary rail system terminus is at the Civic Center Station, enhanced bus service will be provided to get riders to their final destinations. The City’s Department of Transportation Services (DTS) operates TheBus and Handi-Van and will also be operating the rail system. Frequent bus service will be available for rail riders at both the Downtown Station and the Civic Center Station, some with direct bus service to Waikiki, UH and to the Ala Moana Transit Center, where connections to other buses can be made.
It is interesting that, in the original ridership forecast for the Project, only 10 percent of the anticipated rail passengers were expected to have Kakaako or Ala Moana as their final destinations – meaning that 90 percent of the anticipated passengers would have exited rail before, or at, the Civic Center Station or would have boarded a bus at the Ala Moana Transit Center to get to their final destinations. Boarding a bus at the Downtown Station or the Civic Center Station will provide very comparable transit service to those passengers whose travel extends beyond Ala Moana.
There are several reasons that a street-level rail system would not be feasible at this point of the Honolulu rail project, including:
- One significant reason is that the rail system is powered via a “third rail”, which is literally a separate rail that runs alongside the tracks. The trains receive electricity from the third rail, which carries 750 volts of electricity. Having a street-level system would require significant barriers to protect the public from the dangers of the third rail, which is currently achieved with the elevated guideway system.
- Another reason that a street-level system would be problematic is that the trains are expected to have approximate 6-minute headways (the time between trains) during peak hours of operation. That means, for a street-level system, certain intersections all along the route would need to be closed to traffic and pedestrians at least every 6 minutes for a train to pass. This would create additional traffic congestion on our streets that is avoided with the elevated guideway.
The planned 1,600-stall parking garage at the Pearl Highlands station will be deferred due to the excessive cost of building it at the originally planned location. However, HART and the City’s Department of Transportation Services (DTS) are committed to working together to find an alternative location for a garage. Several potential options have been discussed but much more research will need to be done before a plan can be developed.
In the meantime, DTS will add additional and enhanced bus service from North Shore and Central Oahu locations that will enable passengers to board the rail system at a planned bus transit center that will be built directly adjacent to the Pearl Highlands Station.
HART has, and continues to be, diligent in searching for ways to reduce the funding shortfall – and ultimately to get the Project to Ala Moana. Some ways that the shortfall is being addressed:
- Internal Cost Reductions: HART continues to look for ways to reduce its internal costs, including ways to improve efficiencies of internal processes, eliminate redundancies and better manage costs. An example is a 2021 streamlining of the organizational structure that will save $150–200 million over the remaining life of the project.
- Efficient Construction: Ways of reducing construction-related costs are also being evaluated. An example is the decision to implement a shift of a section of the guideway route along Dillingham Boulevard from the middle of the street to the mauka side, thereby eliminating the need to relocate certain utilities. This “mauka shift” will save approximately $150 million.
- Risk Mitigation: Risk reduction actions have been implemented, and are evaluated on an on-going basis, which will reduce future costs of procurement. A good example of risk mitigation is the work by HART to get the utility designs completed and approved before awarding the two recent utility relocation contracts. This work will save construction costs and also shorten the work schedule, adding to the construction savings. In the past, HART had awarded contracts without approved final designs, which is a considerable risk to the contractors proposing on the construction work.
- Seeking New Funding: In addition to the Recovery Plan, HART continues seeking new revenue sources for the Project.
The Mauka Shift refers to a plan to move a section of the rail guideway from the center of Dillingham Boulevard to the mauka side of the street. This mauka shift saves time and money for the Project by eliminating the need to relocate certain utilities.
Currently there is a complex web of electricity, water, sewer and fiber optics lines that run under Dillingham Boulevard. There are also two 138-kilovolt power transmission lines above ground on either side of Dillingham Boulevard. On the makai side, there are also 12- and 48-kilovolt power lines. For HART to move all of these power lines underground would be extremely difficult as there is not enough room to provide the clearances needed to service existing utilities. Moving the guideway to the mauka side of the street eliminates the need to bury all of the power lines on the makai side and avoids the need to move other existing underground utilities, thereby improving the Project schedule and reducing costs by approximately $150 million.
“City Center” is a term used to describe the last construction in the third segment of the Rail Project, comprised of the Dillingham Boulevard, Iwilei, Downtown, and Kakaako areas.
The major scope elements for Utilities Relocation include the movement of storm drainage facilities, sewer facilities, water main, gas/fuel, electrical and communications infrastructure, and roadway improvements to facilitate the installation of the guideway columns in the subsequent phase of work. The City Center Guideway and Stations construction work, a design-build and contract award, is to be procured and anticipated to be awarded in 2024. Once the utility relocation work is completed in these areas, the City Center Guideway and Stations construction work will begin.
The City Center Utilities Relocation project consists of (3) three separate contracts:
- Downtown Utilities Relocation: This project is underway from Kaaahi Street to Cooke Street, along Nimitz Highway and Halekauwila Street, ending at the at the intersection of Coral Street and Halekauwila Street. The contract was awarded to Frank V. Coluccio Construction Company (FVCCC), and the roadway work began in June 2022. Completion is expected in late 2024.
- Dillingham Utilities Relocation: Work is ongoing in the Kalihi-Palama area beginning on Kamehameha Highway from Middle Street to the corner of Dillingham Boulevard and Kaaahi Street. The contract was awarded to Nan, Inc., and the roadway work began in December 2022. Completion is expected in early 2026.
- • The Design-Build Contract procurement for the construction of the City Center Guideway and Stations has begun on April 4, 2023, with the issuance of Request for Proposals Part 1. The contract award is expected in mid-2024.
Once the City Center Guideway and Stations contract has been awarded and the utility relocation has been completed, construction of the elevated guideway and 6 stations from east of the Middle Street-Kalihi Transit Center Station to the Civic Center Station will begin.
About the utilities relocation construction work:
Construction crews will “pothole” to confirm the location of the underground utilities, “jet grout” to control groundwater during construction, excavate and place new utility infrastructure, switch the services over to the new infrastructure, remove the old utility lines, and backfill and repave the street.
Yes, steel plates will likely be used in some areas. For example, HART’s contractor for the Downtown Utilities Relocation, Frank V. Coluccio Construction Company (FVCCC), will place cold mix asphalt around the edges of the steel plates to provide a smoother transition. Also, FVCCC will tack weld multiple road plates together to avoid an abrupt edge to help minimize the noise from vehicles driving over steel plates.
Downtown Utilities Relocation work takes place during two shifts Monday through Saturday from 7:30 am to 5:30 pm and 8 pm to 5 am.
Dillingham Utilities Relocation work is ongoing on Kamehameha Highway and Dillingham Boulevard, from Middle Street to Kaaahi Street, and will operate with one traffic lane in each direction 24 hours a day, 7 days a week.
- Left turns from Kamehameha Highway and Dillingham Boulevard, from Middle Street to Kaaahi Street, will be restricted. Left turns from driveways will also be restricted.
- Through lanes and turn lanes along cross streets at the intersections of Kamehameha Highway and Dillingham Boulevard may be closed during weeknights from 7 pm to 5 am.

A hammerhead is a cement “cap” that is built on the top of the rail guideway columns at the location of the rail stations. The hammerhead extends from the guideway column and supports the rail station platform girders.
Hammerhead Repair Update:
All of the hammerhead repair and retrofit work that was done to protect against corrosion, add additional structural strength, and protect against any future cracking was successfully completed on May 21, 2023.
Trial Running began on August 29, 2022, and was the final series of testing before the rail system is ready to be put into operation. Trains have been moving along the tracks from Kualaka‘i (East Kapolei) Station to Hālawa (Aloha Stadium) Stations—24 hours a day, 7 days a week. The 144 scenarios of normal and emergency operations were tested and the scenario testing was successfully completed in February 2023.
As a part of the comprehensive testing of all aspects of the operations, the Trial Running phase involved simulating various normal and emergency operating scenarios, including:
System Demonstration phase
- Simulated the system’s operation as if it was open to the public.
- To meet the required reliability standards during revenue-like operations, a 30-day rolling average of 98.5% reliability had to be achieved.
- This milestone was successfully achieved on April 2, 2023.
Rail System Completion Update
- In preparation for the initial opening of rail, the Trial Running test phase was completed in early April 2, 2023. This comprehensive testing program was the final series of tests before the system can be put into operation.
- HART finalized the safety certifications of all required operational and safety testing to ensure a smooth turn-over of assets to the Department of Transportation Services (DTS).
- The Honolulu rail system, officially named the Skyline opened on June 30, 2023.
The trains are powered by a “Third Rail” that runs alongside the rail tracks and carries 750 volts of electricity 24 hours a day, seven days a week. Touching the third rail will result in death. The public should avoid the rail tracks at all times. Entry to all rail stations that are still under construction, the Rail Operations Center, the rail guideway and all work sites is strictly prohibited.
Additionally, when driving near the rail guideway, look ahead, not overhead. Do not watch the trains or photograph the trains while driving. Keep your attention on the road.
In late 2020, it was discovered that there was a misalignment of the wheels and rails in the double-crossovers (also known as “frogs”) due to the wheels being too narrow. As a precaution, speed restrictions were put in place for all trains traveling through the double-crossovers. An independent industry expert was engaged to evaluate the situation and recommend a solution. The recommendation, that was agreed to by HART, DTS and HDOT, included a short-term solution of performing a weld of the double-crossovers to fill the gap caused by the narrow wheels. The permanent solution is to replace the wheels. The welding work has been completed. Wheel replacements on the fleet of vehicles has begun. All trains will eventually be fitted with the new wheels.
It was also discovered that the track gauge in certain areas of the double crossovers was too tight. The tracks have been adjusted and the gauge issue has been resolved. Based on the work that has been performed, tested and approved, the speed restrictions for the trains has been lifted and normal testing operations are underway.
Benefits of the elevated guideway include an exclusive right-of-way, free from street-level hazards such as cars, pedestrians, bicyclists, and other modes of transportation along the east-west corridor. Grade separation is also necessary to maintain and support the goal of having a consistent and reliable schedule because train vehicles are not subject to street-level congestion, which can cause delays. An elevated guideway also minimizes the “transit footprint” of the system by minimizing the land that would be needed to build a street-level system in the midst of current traffic lanes.
The Overall Construction and Design Project Progress is based on the Estimate at Completion for the 2022 Recovery Plan scope to Ka‘ākaukukui (Civic Center) Station and the March 2031 Operational Readiness date.
