Oahu Hawaii - 1973
Interstate H-2 under construction in 1973.

Interstate H-2 replaced Route 99 as the through route between Wahiawa and Pearl City. The freeway is named the Veterans’ Memorial Freeway, with signs posted at each end.

I-H2 starts out paralleling 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 weaves northward through western reaches of Schofield Barracks to encircle Wheeler AAF. The freeway ends as Wilikina Drive (Route 99) ahead of Kunia Road (Route 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.
