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.

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.

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.
