Hilo is the hub of the Big Island's east side, and every major road out of town starts here. Highway 11 runs south along Kanoelehua Avenue toward Keaau and climbs to Volcano and Hawaii Volcanoes National Park. Highway 19 heads north up the Hamakua Coast through deep gulches toward Honokaa. Saddle Road, now the Daniel K. Inouye Highway, crosses between Mauna Kea and Mauna Loa to the Kona side, and Highway 130 branches off at Keaau into the Puna subdivisions.
In town, Kamehameha Avenue follows the bayfront, Waianuenue Avenue climbs toward Rainbow Falls and Kaumana, and Puainako Street links the shopping corridor with the upper Waiakea neighborhoods. Hilo's older streets were laid out long before modern traffic, so downtown blocks are short and many side streets have no shoulder at all. Traffic is light by Oahu standards, but the distances are long. A breakdown near the Saddle Road summit or on a lonely stretch of Highway 130 can leave you far from help, which is exactly when an on-site repair beats a tow across the island.
Hilo International Airport sits on the east edge of town near Keaukaha, and Hilo Harbor beside it is where barges bring in nearly everything the east side uses, auto parts included. The Hele-On bus connects Hilo with Puna, Hamakua and Kona on limited schedules, so most people here depend on their car and want it fixed where it sits.
