The Nuʻuanu Pali Tunnels are a set of four highway tunnels (two in each direction) on the Pali Highway (Hawaii State Highway 61) which pass through the Nuʻuanu Pali. These tunnels serve as one of three trans-Koʻolau routes between Honolulu (leeward Oʻahu) and the communities of windward Oʻahu. Also, the Nuuanu Pali Tunnels serve as a major transportation route from Kaneohe 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.
