It begins in downtown Wailuku, extending south through Waikapu and Māʻalaea before turning west. This portion of the highway, between Māʻalaea and Olowalu, is also known as the pali (Hawaiian for "cliff"), as the highway winds between large cliff faces.[2][3] This part of the highway, which opened in 1951, replaced a one-lane road higher in the hills. The highway then passes through the 318 feet (97 m) long Pali Tunnel, located at mile 10.4.[4][5]
Following the terrain of the island, the highway continues to circumvent the West Maui Forest Reserve connecting Olowalu, Launiupoko, Lahaina, Kahana, through the regions of Kapalua and Honolua, and ending in Honokohau Bay. At this point the road continues as the Kahekili Highway, a "notoriously narrow and twisty" county-maintained road covering the northern coastline of West Maui and eventually terminating back in Wailuku.[6] The eastern part of Kahekili Highway is signed as Hawaii Route 340. The two highways together, plus a short stretch of Hawaii Route 32, complete the circular journey around West Maui.

Hawaii Route 3000, also known as the Lahaina Bypass, is a highway that bypasses the town of Lahaina. The bypass opened to the public on April 23, 2018.[8]
The bypass has its northern terminus in Downtown Lahaina along Keawe Street, before becoming the Lahaina Bypass, a four lane highway with occasional at-grade intersections, looping around the town, ending its at southern terminus at the Honoapiilani Highway.[8]
Hawaii DOT plans call for the bypass to be extended to the north for about 5 miles (8 km). There is widespread support in Lahaina for such an extension,[9] but as of 2025 there is no timeline for construction.[10]
