Hawaii Route 31, also known as the Pi'ilani Highway, is a 38-mile road^[1][2] on the island of Maui in the U.S. state of Hawaii. The state road begins in at an intersection with Hawaii Routes 310 and 311 in the West Maui town of Kihei. The highway formerly ran parallel to the coast all the way to the southern terminus of the Hana Highway (Route 360), until developments in Wailea and Makena blocked access.. The Kihei section of the highway now terminates in Wailea, and the much longer Kaupo section, which is county-maintained as County Road 31, connects Route 37 near Kula to the Route 360 south of Hana (at the western border of Haleakala National Park).

Major intersections

The entire route is in Maui County.
