Route 72, commonly known as Kalanianaʻole Highway, is the main highway serving southeast Oʻahu. Beginning at the eastern terminus of Interstate H-1 (H-1), the east–west highway travels along the southeastern shore of Oʻahu through various residential neighborhoods, including Hawaiʻi Kai. It turns northwest at Makapuʻu and runs through Waimānalo before terminating in Maunawili at an intersection with Kamehameha Highway and Pali Highway. The highway is named for Jonah Kūhiō Kalanianaʻole, a former prince of the Kingdom of Hawaiʻi.
