Hawaii Route 61, often called the Pali Highway, is in Honolulu County, Hawaii, United States, that is the main highway connecting downtown Honolulu with the windward side of Oʻahu island. From downtown, it traverses up Nuʻuanu Valley and the residential neighborhood of Nuʻuanu, passes through the Nuʻuanu Pali Tunnels, and descends to the major windward communities of Kāneʻohe (reached by Kamehameha Highway, State Route 83) and Kailua.
