Route descriptionEdit

Route 50 southbound at Route 58 in Lihuʻe

Hawaii Route 50 begins in Lihuʻe and heads west. The road passes through the only major shopping center on the island at the intersection with Route 58. From there, the road passes through the countryside and several small communities. There are numerous agricultural farms and plantations set up along the route. The National Historic Landmark known as Russian Fort Elizabeth is located where the highway crosses the Waimea River.[4]

The last major sugarcane plantation on Kauaʻi is along the route west of Waimea.[5] West of Waimea, Route 50 serves only as an access road to 4 major sites: Pacific Missile Range Facility, Polihale Beach, Kekaha Town, and Waimea Canyon via Route 550. The only public services available west of Waimea are a collection of tourist shops and a convenience store at the base of Route 550. Route 50 is named after Kaumualiʻi, the last king of the island of Kauaʻi.
