The alternate Road to Hana
The most frequently traveled Road to Hana is along the North Coast of Maui through the Rainforest.
Along the skirt of Haleakala volcano, the alternate Road to Hana (Piilani Highway) is across the barren, lava desert of the South Coast of Maui - pictured here. This route had been closed for nearly two years following the October 15, 2006 Kiholo Bay earthquake. The 6.7 earthquake caused rockfalls, destabilized cliff faces and undermined sections of the road.
The Hāna Highway (also known as the Hana Road or Road To Hana) is the name given to the 68-mile (109 km) long stretch of Hawaii State Highways 36 and 360 which connect the population center of Kahului with the town of Hāna in east Maui. On the east after Kalepa bridge, Hana Highway continues to Kīpahulu as Hawaii Highway 31 (Piilani Highway), the first section of which is unofficially considered to be part of Hāna Highway. Although Hāna is only about 52 miles (84 km) from Kahului, a typical trip to Hāna takes about three hours, as the road is very winding and narrow and passes over 59 bridges, 46 of which are only one-lane bridges, requiring oncoming traffic to yield and occasionally causing brief traffic jams if two vehicles meet head-on. There are approximately 620 curves along Highway 360 from just east of Kahului to Hana, virtually 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 paralleled by a portable steel Bailey bridge erected by the United States Army Corps of Engineers. Signs on the old bridge warn pedestrians to stay off due to imminent collapse. (Wikipedia)
