Kamehameha Highway is one of the main highways serving suburban and rural O‘ahu in the U.S. state of Hawaii. Starting from Nimitz Highway near Pearl Harbor and Hickam Air Force Base in Honolulu, it serves the island's older western suburbs, turning north across the O‘ahu Central Valley to the North Shore. At the North Shore, Kamehameha Highway heads northeast around the northern tip of O‘ahu, then southeast to and just beyond Kāne‘ohe Bay on the windward coast. The road was named after King Kamehameha I. A short detached segment of the Kamehameha Highway exists for a few blocks in the Honolulu neighborhood of Kalihi. This segment runs as a short extension of Dillingham Boulevard from Puuhale Road to exit 18B on Interstate H-1. This section was contiguous with the rest of the highway before the construction of the H-1 viaduct.
As Route 99, Kamehameha Highway begins at its southern terminus at the Pearl Harbor interchange of Interstate H-1 near Pearl Harbor and Hickam Air Force Base. The highway runs north past the Pearl Harbor historic sites such as the USS Arizona Memorial and the, the Admiral Clarey Bridge to Ford Island leading to the, and Aloha Stadium. The highway then turns west through the suburbs of Aiea and Pearl City, passing Pearlridge Center, the state's second largest shopping mall. After passing Pearl City and the interchange with Interstate H-2 near Waipahu, Route 99 turns north through the central O'ahu suburbs of Waipio and Mililani. South of Wahiawā near Wheeler Army Airfield, the named Kamehameha Highway continues through Wahiawā as Route 80, while Route 99 bypasses Wahiawā on the west, rejoining Kamehameha Highway north of Whitmore Village. It then continues north through pineapple fields and former sugar cane fields to the junction with Route 83 near Haleiwa.
Route 80 (Wahiawa)
As Route 80, Kamehameha Highway begins at the interchange with Interstate H-2 and Route 99 and passes through central Wahiawā and passing Whitmore Village before rejoining Route 99 north of Wahiawa.
Originally, Kamehameha Highway continued as Route 83 at the junction with Route 99 at Weed Junction in Haleiwa, passing through Haleiwa up the North Shore. Since 1996, Route 83 begins inland from Weed Junction as the Joseph P. Leong Highway and bypasses Haleiwa town on the inland side, rejoining Kamehameha Highway north of Haleiwa. From Haleiwa, Kamehameha Highway passes Waimea Bay, Sunset Beach, and the Turtle Bay Resort at the northern tip of O'ahu before heading down the Windward Coast communities of Lai'e, Hau'ula, Punalu'u, and Ka'a'awa. At Kahalu'u, Kamehameha Highway follows the coastline through He'eia and the main commercial district of Kaneohe, while Route 83 continues as Kahekili Highway bypassing Kaneohe town to the west before reaching the junction with Likelike Highway. Route 83 rejoins Kamehameha Highway in Kaneohe and continues south to the interchange with Interstate H-3 and the eastern terminus at Route 61.
