Project Overview: The City and County of Honolulu began this roadway improvement project in the 1970s to increase the capacity of Salt Lake Boulevard to accommodate rapid growth in the Salt Lake Community. Implementation of the project was undertaken in phases. The eastern section between Puʻuloa Road and Ala Lilikoʻi Street was the first phase constructed. Phase 2 completed the western end from Kahuapaʻani Street to Maluna Street in 2005.

Phase 3 encompasses the remaining unimproved section of Salt Lake Boulevard from Maluna Street to Ala Lilikoʻi Street. Its completion will finally provide sidewalks and multiple travel lanes for the entire length of Salt Lake Boulevard. The project is being designed as a Complete Street, consistent with the City’s commitment to providing facilities for all roadway users. Other notable design features include green infrastructure to address stormwater quality and protected bicycle lanes for riders of all ages and abilities. The Salt Lake community has been waiting decades for this project and is eager for its completion.

Construction is now underway on Phase 3A, which will include sidewalks, curbing, curb ramps, and bikeway improvements on the makai side of the unimproved section. Additionally, “green infrastructure” will be incorporated to treat stormwater on-site and physically separate people riding bikes from vehicular traffic. The estimated completion of this phase is Fall of 2026

The final Phase 3B improvements will include all remaining elements: additional traffic lanes, completion of the drainage system, traffic signal changes, utility relocations, and the mauka-side curbs, sidewalk, and bike lane.
