Kamehameha Highway

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.

Note that Kamehameha Highway is a "fractured" roadway and that the discussion below is for its more well-known route as State Highway 99. Kamehameha Highway actually starts east of the southern terminus noted below, at the intersection of Dillingham Boulevard and Puuhale Road near the Oahu Community Correctional Center in Kalihi continuing west until the H-1 Viaduct. It is said that this very short segment of Kamehameha Highway is a remnant left over from the days before construction of the elevated H-1 Freeway Airport Viaduct. Indeed, some long-time locals will maintain that the east-bound section of roadway under the Viaduct is Nimitz Highway whereas the west-bound section is Kamehemeha Highway. Since there are no businesses or other addresses along the west-bound section under the Viaduct, there is nothing to support this assertion.

Route 99 (Honolulu to Haleiwa)

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 USS Bowfin, the Admiral Clarey Bridge to Ford Island leading to the USS Missouri, 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 (as Wilikina Drive and Kamananui Road) 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.

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 (this segment was formerly Route 836), while Route 83 continues as Kahekili Highway bypassing Kaneohe town to the west before reaching the junction with Likelike Highway (Route 63). Route 83 rejoins Kamehameha Highway in Kaneohe and continues south to the interchange with Interstate H-3 and the eastern terminus at Route 61.
