The Nuʻuanu Pali Tunnels are a set of four highway tunnels (two in each direction) on the Pali Highway (Hawaii Route 61) which pass through the Nuʻuanu Pali in Hawaii, United States. These tunnels serve as one of three trans-Koʻolau routes between Honolulu (leeward Oʻahu) and the communities of windward Oʻahu. Also, the Nuʻuanu Pali Tunnels serve as a major transportation route from Kāneʻohe and Kailua over to Honolulu. These tunnels and the Pali Highway were built to provide a safer route through the mountain ridge, replacing a narrow, winding, and dangerous road over the mountain.
