City and County of Honolulu and Hawaii Department of Transportation are collaborating on several improvement projects along Pali Highway.

  • Dowsett Highlands Relief Sewer
  • Street lighting (Vineyard to Kamehameha)
  • Highway resurfacing
    (Waokanaka to Kamehameha and Vineyard to Waokanaka)


The City and County of Honolulu (City) and the Hawaii Department of Transportation (HDOT) are working on several improvement projects on Pali Highway including street lighting, resurfacing and sewer system upgrades. To minimize impact on local communities and commuters, the City and HDOT are collaborating on scheduling, planning and overall project coordination.

Project 1: HDOT’s Pali Highway – Street Lighting & Resurfacing

Scheduled to Begin: July – September 2017
This project involves replacing the lights from Vineyard Boulevard to Kamehameha Highway with an LED lighting system, and street resurfacing from Waokanaka Street to Kamehameha Highway.

Project 2: City’s Dowsett Highlands Relief Sewer

Scheduled to Begin: June 2018
This project involves a significant upgrade in Nuuanu Valley. A new sewer main will be installed along Dowsett Avenue, Pali Highway and Nuuanu Avenue to relieve two under-capacity sewer mains (the Waolani Stream and Nuuanu Stream sewer mains).

Project 3: HDOT’s Pali Highway – Street Resurfacing

Scheduled to Begin: December 2018
Once the sewer main project is finished, street resurfacing from Vineyard Boulevard to Waokanaka Street will commence. The improved corridor will increase safety and provide a smoother driving experience.

The City and HDOT are collaborating to ensure projects are scheduled accordingly so work is seamless and coordinated. As part of Project 1, HDOT will install work zones and traffic lane modifications in order to complete the street lighting project. These areas will also be used by the City for its sewer main project. HDOT will maintain all three Honolulu-bound lanes in the work area during peak travel hours for the duration of work in Nuuanu Valley.
