Beginning at the eastern terminus of Interstate H-1 (H-1), the eastâÂÂwest highway travels along the southeastern shore of Oahu through various residential neighborhoods, including Hawaii Kai. It turns northwest at Makapuu and runs through WaimÃÂnalo before terminating in Maunawili at an intersection with Kamehameha Highway and Pali Highway. The highway is named for Jonah Kà «hià  Kalanianaole, a former prince of the Kingdom of Hawaii.

The highway turns southeast near Hawaiûi Kai, crossing the inland waters of the Kui Channel and climbing part of Koko Crater.
The highway was named for Jonah Kà «hià  Kalanianaûole, a Hawaiian prince and later Congressman who attempted to restore Queen Liliûuokalani to the throne after the 1893 overthrow by American residents.
