The Hana Highway (colloquially referred to as The Road to Hana) is a stretch of Hawaii Routes 36 and 360 which connects Kahului to the town of Hana in east Maui. To the east of Kalepa Bridge, the highway continues to Kipahulu as Hawaii Route 31 (the Piilani Highway). Although Hana is only about from Kahului, an uninterrupted car-trip takes about 2.5 hours to drive, since the highway is very windy, narrow, and passes over 59 bridges, of which 46 are only one lane wide. There are approximately 620 curves along Route 360 from just east of Kahului to Hana, almost all of it through lush, tropical rainforest. Many of the concrete and steel bridges date back to 1910 and all but one are still in use. That one bridge, badly damaged by erosion, has been replaced by a portable steel ACROW or Bailey bridge erected by the United States Army Corps of Engineers. In August 2000, the highway was designated as the Hana Millennium Legacy Trail by President Bill Clinton, with the trail start designated in Pāia. The Hana Highway was listed on the National Register of Historic Places on June 15, 2001. Route description Hana Highway consists of Hawaii Routes 36 and 360. Route 36 is a mixture of urban street, divided highway, and high-speed rural highway. Route 360 is a narrow and winding mountain road. Mileposts in tourist guides refer to mile markers on Route 360, not Route 36. Route 36 begins in Kahului and the junction of Routes 32 and 311, and the road named Hana Highway begins one block east. The highway runs east as a four-lane divided highway, intersecting with Routes 380, 3800 which serve Kahului Airport to the north and connect to Maalaea and West Maui to the south. A short distance east, it intersects Route 37, which serves Haleakala to the south. East of this point, the highway becomes a two-lane rural highway, passing through Pa'ia and Ha'iku. Highway 36 ends at Route 365 east of Haiku, while the Hana Highway continues as Route 360. Highway 360 is a narrow, winding, and low speed mountain highway. Its initial junction is marked as Mile Zero at Route 36, and the highway runs in a southeasterly direction toward Hana. This highway includes numerous one-lane stretches of roadway, including one-lane bridges. The road provides access to the community of Keanae, Wailua, and Nahiku, arriving at
