The Hospital Rock Tunnels are a small pair of highway tunnels passing through a ridge on the edge of the Ko‘olau Range on the island of O‘ahu. The tunnels are located on Interstate H-3, which connects Kaneohe with Interstate H-1 at Hālawa near Pearl Harbor, and are 354 feet (108 m) long Kaneohe bound and 353 feet (108 m) long Halawa bound. The tunnels are "cut and cover" tunnels, having no lighting system of their own.
