Road conditions
Every closure and crash Hawaii DOT is publishing, on one map with the route and mile marker. Below it: and what the season does to Hawaii's highways. For the whole country, see the US closures map.

ReportWhat the Hawaii DOT feed carried over the holiday weekend.
H-1 is Oahu's spine, from Kalaeloa past Pearl Harbor and the airport through downtown Honolulu to Kahala. H-2 heads north from H-1 toward Wahiawa, and H-3 crosses the Koolau Range to Kaneohe. On Maui, the Hana Highway, Routes 36 and 360, winds the Road to Hana. On the Big Island, Route 11 and Route 19 circle the island through Kona and Hilo.
Hawaii's hazards are tropical. Heavy rain floods the low crossings, rockfall and landslides hit the coastal cliff roads, and the Big Island sees the occasional lava-adjacent closure. On the Hana Highway and Kauai's north shore there is often exactly one way in and one way out, so a single closure changes the whole day's plan.
Over 25 daily snapshots from September 1 to 25, 2026, MileCheck's archive of the Hawaii DOT feed held 13 unique reports, including 13 work-zone reports. The routes with the most reports were HI-92 and HI-30. Counts reflect what the feed publishes, so a state whose DOT posts only closures shows only closures. Read the September Highway Report.
The map above shows every full closure Hawaii DOT is publishing as a red marker, crashes in orange, and weather and hazard alerts in blue and purple. Closures the DOT has posted for a future date are listed as scheduled, and ramp and lane closures sit under the toggle so the list stays readable. It reloads every five minutes. If the feed cannot be reached the page says so instead of showing an empty map. For the official list, open Hawaii DOT.
