Rehabilitation of Numana Bridge

The City and County of Honolulu’s Department of Design and Construction will begin rehabilitation work on the Numana Road Bridge No. 129, over Kalihi Stream in Kalihi Valley. The intent of the project is to improve the bridge's structural integrity, thereby enhancing its longevity and public safety. Work includes demolition and removal of select bridge and roadway elements, construction of new bridge deck, beams, curbs, railings, and guardrails, repairs to existing concrete spalls, cracks, and voids at the abutments and piers, and roadway resurfacing.

Construction is scheduled to begin on Monday, August 17, 2026, and is expected to continue for approximately seven (7) months, barring unforeseen conditions and 

weather events. Work hours will be Monday through Friday, from 8:30 a.m. to 3:30 p.m., excluding holidays.

Temporary traffic changes will be required throughout the project duration. Mid-August 2026: One travel lane will remain open during weekday work hours (8:30 a.m. – 3:30 p.m.), with vehicles alternating in both directions under the guidance of traffic control personnel. Late August through late December 2026: A full bridge closure will be in effect 24 hours a day, seven days a week to safely accommodate major construction activities. Traffic will be detoured using the approved detour route. Early January through mid-February 2027: The bridge will return to one-lane alternating traffic during weekday work hours (8:30 a.m. – 3:30 p.m.), with vehicles alternating in both directions under the guidance of traffic control personnel. No weekend lane closures are anticipated during the August and January through February one-lane traffic phases, weather and field conditions permitting. Motorists should allow extra travel time and follow all posted signs, traffic control devices, and traffic control personnel when traveling through the area.
