Updated on Nov. 6, 2026 in Construction
The Honolulu Authority for Rapid Transportation began guideway construction on Halekauwila Street on October 26, with the first section running between Richards and Punchbowl Streets. Work on that section is expected to last about one month.
Why it matters
The start of guideway work marks a visible step forward for the Skyline transit project as segments move from utility relocation into structural construction. Residents and drivers near the corridor will see changing traffic patterns as crews advance.
Skyline Segment 3 has completed 38 of 148 shafts, 23 of 148 columns, and 6 of 148 caps, showing early-stage progress across the segment. Utility relocation between Kamehameha Highway and Dillingham Boulevard is 97% complete for dry and wet utilities and 74% complete for electric, with the full project timeline not yet specified.

October 2026: Skyline Segment 3 shaft, column, and cap progress was reported.
Market Landscape
The guideway start extends the Skyline elevated rail project, first authorized as part of Honolulu's long-running rail transit plan, from utility relocation into structural work on its planned route. Progress on Segment 3 places the project in the foundation and column phase that typically precedes deck and station installation.
Drivers on Halekauwila Street and nearby corridors should expect new traffic plans while crews work on the first guideway section over roughly one month. Commuters in the Kakaako and Iwilei areas may see lane changes and detours as construction continues.
The takeaway
Major infrastructure projects advance in stages, and short-term traffic adjustments are often the first visible sign of progress. Checking official project updates before commuting can help drivers plan around construction zones.
