The Hana Highway (colloquially referred to as The Road to Hana) is a 64.4-mile-long (103.6 km) 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 52 miles (84 km) from Kahului, an uninterrupted car-trip takes about 2.5 hours to drive, since the highway is very winding, 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, was temporarily replaced by a portable steel ACROW or Bailey bridge erected by the United States Army Corps of Engineers until a permanent replacement was built in 2009.
In August 2000, the highway was designated as the Hana Millennium Legacy Trail by President Bill Clinton, with the trail start designated in Pāʻia. The Hana Highway was listed on the National Register of Historic Places on June 15, 2001.
