Nuʻuanu Pali Tunnels
The Nuuanu Pali Tunnels are a set of four highway tunnels on the Pali Highway which pass through the Nuuanu Pali. These tunnels serve as one of three trans-Koolau routes between Honolulu and the communities of windward Oahu.
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.
