The Hawai‘i Department of Transportation, Goodfellow Bros. Inc. and all project team members have announced that Queen Ka‘ahumanu Highway Phase 2 construction will resume Monday, Jan. 30, 2017.

The work will involve excavation of retaining walls near the national park; traffic signal, interconnect and street light foundation and conduit installation at multiple locations on the north end of the project; and reclaimed water utility installation and testing. This will be followed by subgrade preparation for aggregate base course and pavement and further utility work.

HDOT is coordinating the protection of the State Inventory of Historic Place (SIHP) #10714 and SIHP #00002 sites affected by the prior breaches and has been able to lift stop-work orders in those areas.


The redesign of the project on the south end between Kealakehe Parkway and Hulikoa Drive for the Section 106 and Section 4(f) process is nearing completion. Retaining wall designs are being submitted and reviewed with the drainage design to follow.

HDOT continues to work with the appropriate parties to revise the project Area of Potential Effect (APE) and expects resolution in a matter of weeks. Once the revised APE is accepted by the State Historic Preservation Division, the construction of the utility crossing at Kealakehe Parkway can be scheduled.

This specific work will occur during nighttime hours in an attempt to limit impacts to traffic.


HDOT and GBI anticipate beginning construction of the pavement structure at the Hulikoa intersection in the near future. The additional work at this intersection includes the installation of temporary traffic signal heads on the existing Queen Kaʻahumanu Highway lanes, temporary pavement and new striping for that intersection as it currently is not signalized.

Retaining wall construction is anticipated to take multiple months to complete. As retaining walls are completed on the north end of the project, subgrade, aggregate base course, and pavement will follow.

The construction end date has not been finalized as first priority has been to resolve the issues attributable to the work stoppage to allow GBI to recommence construction. Now that construction is resuming, HDOT, GBI and the Project Team members are examining schedule impacts as well as opportunities that will allow for expedition of the project with the goal of keeping the completion date as close to the initial contract date as possible. Additional details will be given once rescheduling is done.


Mahalo for your patience, and we look forward to a successful and safe construction project. Future announcements will be issued as work progresses.

Message boards, HDOT news releases, and notices posted to the website will alert the public to upcoming work.
