Commuters take note.
Around-the-clock traffic adjustments are coming to Kamehameha Highway and Dillingham Boulevard as construction of the Skyline rail progresses.
In the coming weeks, HART, or the Honolulu Authority for Rapid Transportation — the public transit authority responsible for planning and building the rail system for the City and County of Honolulu — and Tutor Perini Corp., its contractor for the City Center Guideway and Stations, or CCGS, project, will implement a revised traffic plan for the roadways, beginning with a section of road between Middle Street and Pu‘uhale Road.
The traffic adjustments will be in place 24/7 from March 2026 through December 2030.
HART says that as work along Kamehameha Highway and Dillingham Boulevard moves from utility relocation to guideway and station construction, “traffic plans will be adjusted to accommodate the work.”
“For this first section, between Middle Street and Pu‘uhale Road, one travel lane in each direction will remain open on the mauka side of the street, with barriers installed to safely separate the construction zone from the travel lanes, and the current left turn restrictions will remain in place,” HART notes. “Driveway modifications may be needed, however access to all properties will be maintained.”

HART, broke ground in August on the CCGS portion of the rail project.
The CCGS project includes the construction of nearly three miles of elevated guideway and six rail stations, starting near Kahauiki, or the Middle Street Transit Center station, and ending at the Civic Center station, just east of the intersection of Halekauwila and South streets, ASD previously reported. Construction is expected to be finished by 2030.
HART awarded a $1.66 billion contract for the design and construction of the CCGS project to Tutor Perini Corp. in August 2024.
The first segment of the rail opened in June 2023 and spans just under 11 miles from East Kapolei to Aloha Stadium. Meanwhile, the second segment — 5.2 miles of guideway that runs from Aloha Stadium to the Middle Street Transit Center — opened last October.
Skyline ridership numbers have climbed since the second segment opened and in January, there were a total of 299,961 rides compared to 92,310 rides in January 2025. You can find more ridership data here.
Projected ridership numbers have fluctuated over the years, but a 2022 recovery plan submitted by HART to the Federal Transit Administration — which shortened the scope of the project by postponing 1.25 miles of guideway, the last two stations at Kaka‘ako and Ala Moana, and a garage at Pearl Highlands — the authority estimated about 84,000 daily boardings for the truncated scope.
