Interstate H-2 winds northward from Pearl City and Waipahu to Wahiawa and Wheeler Army Airfield. The route primary serves commuting interests between central Oahu and and Honolulu while providing part of a through route with Hawaii 99 (Kamehameha Highway) to the north shore.

I-H2 starts out parallel to Panakauahi Gulch just east of Waipio. Beyond there, an undeveloped stretch ensues before the freeway curves west across Kipapa Stream through built up areas of Mililani Town and Waipi'o Acres. Crossing a viaduct above Waikakalaua Stream and Waikalani Drive, H2 winds northward through western reaches of Schofield Barracks to encircle Wheeler AAF and end as Wilikina Drive (Hawaii 99) ahead of Kunia Road (Hawaii 750).
Interstate H-2 was included in the 51.2 miles of freeway added to the Eisenhower Interstate and Defense Highway System in 1960.1 Construction on I-H2 commenced in 1972 and was finished in 1975.
