Hawaii 30 - Honoapiilani Highway

Hawaii 30 represents the main access road between the tourist areas of Lahaina, Kaanapali and Kahana with Kahului and Kahului Airport via Hawaii 380 (Kuihelani Highway). The state route generally hugs the coastline from Kaanapali southward to Maalaea. This stretch includes a tunnel between Kamaohi and Mokumana Gulches.



Hawaii 31 - Piilani Highway

Hawaii 31 consists of just 7.15 miles of the Piilani Highway from Kihei south to Keawakapu. Piilani Highway east from Ulupalakua is an unpaved roadway designated as unsigned County Route 31, though the highway was originally Hawaii 31. Hawaii 31 also followed Kihei Road west to Hawaii 30 (Honoapiilani Highway), but that stretch was renumbered to Hawaii 310.



Hawaii 32 - Kaahumanu Avenue

Hawaii 32 connects downtown Wailuku with the central business district of Kahului along Main Street and Kaahumanu Avenue. The short state route is essentially unchanged from its original signing.



Hawaii 32A - Hobron Avenue

Hawaii 32A constitutes a short spur along Hobron Avenue, linking Hawaii 32 and 36 (Hana Highway) with the Port of Kahului.



Former Hawaii 33 - Kahekili Highway

Hawaii 33 was the designation for the Kahekili Highway that meanders northwest from Wailuku to Waihee and Honokohau. The unpaved section of this route is now a part of County Route 340, the paved portion was renumbered to Hawaii 340.



Former Hawaii 34 - Lower Main St / Kahului Beach Rd

Hawaii 34 originally comprised a loop north from Hawaii 32 along Lower Main Street to Kahului Beach Road. The Kahului Beach Road portion was retained in the state system as the eastern half of Hawaii 3400. Lower Main Street was turned back completely.



Former Hawaii 35 - Puunene Avenue / Mokulele Highway

Hawaii 36 - Hana Highway

Hawaii 36 follows the western third of the Hana Highway from Kahului eastward to Lower Paia, Pauwela and County Route 365 (Kaupakalua Road). The state route used to continue all the way to Hana and the north end of Hawaii 31, but that portion of the Hana Highway was renumbered to Hawaii 360.

Historically Hawaii 37 continued west from its current end point at Hana Highway to Hawaii 36 by Kanaha Ponds. A portion of Haleakala Highway through the airport was removed due to runway expansion at the airport. A stretch of Haleakala Highway remains west and east from Keolani Place ahead of the airport terminal. This includes a signed stretch of Hawaii 36A.



Former Hawaii 38 - Dairy Road

Hawaii 38 connected Hawaii 380 / former 35 (Mokulele Highway) with Hawaii 36 (Hana Highway) along Dairy Road in Kahului. Dairy Road is now a part of Hawaii 380.

Former Hawaii 40 - Waiko Road

Hawaii 40 existed in two segments on Maui. The first was an unpaved road connecting Hawaii 30 (Honopiilani Highway) at Waikapu with Mokuele Highway (Hawaii 35 at the time). A portion of this road remains today as Waiko Road.

The eastern Hawaii 40 followed Makawao Avenue northeast from Pukalani and Hawaii 37 to Makawao, Kokomo and Hawaii 360 (Hana Highway), east of Ulumalu. This route was renumbered to Hawaii 400 and later to County Route 365.
