Kamehameha Highway

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.

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,[3] 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.

Hawaii Route 830 is a 5.5-mile-long (8.9 km) north–south route on the island of Oahu in Hawaii. Its northern terminus is with Route 83, near Kahaluu. It then continues southward along the shore of the Kaneohe Bay, until its southern terminus with Routes 63 and 83, only 1.5 miles away from Interstate H3.[4][5][6]
