The H-3 Highway also known as John A. Burns Freeway on the island of O'ahu, is considered one of the most beautiful and most controversial freeway in Hawaii. Completed in 1997, the 16-mile H-3 connects Pearl Harbor Naval Base in Pu‘uloa, on O‘ahu’s southern coast, to the Marine Corps Base Hawaii on Mokapu Peninsula, on O‘ahu’s eastern coast. Interstate H-3 begins at the Hālawa Interchange with Interstates H-1 and H-201. The freeway then runs along a viaduct through Hālawa Valley for about 6 miles, tunnels through the Ko'olau Mountains, takes another viaduct built along the side of Haiku Valley until it reaches the town of Kaneohe. The freeway then continues to the Halekou Interchange finally terminating at the Marine Corps Base Hawaii.
