The Hawaiʻi Department of Transportation will close a single lane on Kaumualiʻi Highway (Route 50) in the vicinity of Kīkīaola Boat Harbor next week to allow crews to permanently replace three 54-inch culverts.
The closure starts on Aug. 26 at 8:30 a.m. and will continue through December. The single-lane closure will be continuous and travel in both directions will be maintained through alternating traffic control (contraflow) in the open lane.
Kaumualiʻi Highway, near Kīkīaola Boat Harbor, was declared a traffic emergency zone in early April due to the roadway showing signs of potential culvert failure. The state completed temporary repairs and roadway reconstruction.
This 24/7 lane closure will allow crews to replace the corrugated metal pipes with reinforced high-density polyethylene pipes and lift the traffic emergency zone designation.
During active construction, flaggers will provide alternating traffic control through the work zone. During non-working hours, traffic control will be provided by temporary traffic signals.
