The City Center Utilities Relocation project moves undergound utilties—such as water, sewer, gas, electrical, and communications lines—to prepare for construction of the rail guideway and stations in the Dillingham, Iwilei, Downtown, and Kakaʻako areas.

The work is divided into three contracts:

• Downtown Utilities Relocation (Kaʻaʻahi Street to Cooke Street): Ongoing since 2022; are nearly complete.
• Dillingham Utilities Relocation (Middle Street to Kaʻaʻahi Street): Ongoing since 2022; are expected to be completed mid-2026.
• City Center Guideway and Stations Construction: Contract awarded in 2024; guideway shaft construction in Iwilei is expected to begin summer 2025.

Crews are relocating utilities, then repaving roads to make way for the next phase of rail construction.
