Kuhio Highway closes at Haena Park as flooding hits north shore

Flooding at Manoa Stream shut Kūhiō Highway at Haena Park, cutting off the north shore road end that serves Hāena State Park, Kee Beach and the access corridor toward Wainiha and Hanalei. The closure also pulled beach protection off the line at Kee and Hāena, where lifeguard stations were shut as rainwater and runoff pushed into the shoreline.

The disruption came after emergency management reported ponding over Kūhiō Highway near Hāena on June 18, with rain falling at 1 to 2 inches an hour. The National Weather Service has said flooding on Kauai can quickly hit roads and low-lying ground, and the county again urged people to avoid all unnecessary travel when severe weather is driving conditions across the island.

Ocean users were also told to stay out of the water. The Kauai County Ocean Safety Bureau advised no swimming or other ocean activities at Hanalei Bay and all north-facing shores other than Anini Beach when runoff and brown water are present, a warning that matters most when the north shore is already cut off by a road closure.

Hāena State Park sits at the northwestern extent of Kūhiō Highway, and state parks officials have repeatedly closed Hāena State Park and the Nā Pali Coast State Wilderness Park during heavy rain, flash flooding and landslides. DLNR has said flood repairs at Hāena were accelerated after the 2018 flood event, a reminder that this stretch of Kauai is vulnerable every time the streams rise.

For now, the practical detour is to turn back before the flooded section, because there is no public through-route into Hāena from the south. In past north shore flood events, Kūhiō Highway reopened only after the National Weather Service canceled its warning and elevated water levels dropped enough for the road to be safe again, which leaves reopening tied to both stream conditions and the weather window.
