The Hana Highway 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, it takes about 2.5 hours to drive even when no stops are made since the highway is very winding and 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 That one bridge, badly damaged by erosion, has been replaced by a portable steel ACROW bridge erected by the United States Army Corps of Engineers.

The Hana Highway is a popular tourist attraction in Maui. Guidebooks often devote large sections to traveling the highway leading to the eastern side of Maui, documenting the many waterfalls and attractions that can be found along the way. Some of these attractions lie within or through private property and will often have "no trespassing" signs posted or even signs claiming that the attraction does not exist. All beaches in Hawaii are public. Some guidebooks document the "keep out" areas and ways past barbed wire fences and locked gates to reach attractions.
Occasionally the dirt road past Route 31 is closed to traffic due to landslides. However, although it is somewhat rough in places, it is by no means a daunting or particularly dangerous road if taken slowly.
Scenic turnouts abound, including one for Wailua Falls near the Seven Sacred Pools in Oheʻo.
in the sixteenth century, Maui's King Pi'ilani conquered East Maui and drew Hana into his political sphere. Pi'ilani built the Alaloa, the "long road," from West Maui, a road on which travelers reportedly swung themselves over East Maui's rushing streams with ropes made of vines. Later, Piilani's son, Kihapiilani, extended the Alaloa into the Hana District. When completed, the road was 4' to 6' wide, 138 miles long, and paved with hand-fitted basalt (lava) rocks. Modern road construction to Hana began in the 1870s, with an unpaved road built to facilitate the construction of the Hämäkua Ditch. Part of The East Maui Irrigation System, the Hämäkua Ditch brought water from the rainforests of Haleakalā to semi-arid central Maui to support the sugarcane industry.
Road construction continued in the early 1900s and was extended piecemeal until the full road to Hana was officially opened on December 18, 1926. Construction of bridges continued through the 1930s and the road was not completely paved until the 1960s.
The entire route is in Maui County.
