Route 93 is a major east - west highway on the island of Oahu which begins as Interstate H-1 (H-1) terminates in Kapolei and ends at Kaena Point on the extreme northwest end of Oahu, just past Makaha. It is part of the Farrington Highway.
As H-1 ends near Kapolei and Ko Olina, it continues as a four lane, and then two lane highway up into the Waianae and Makaha area, the "Leeward Coast", of west Oahu.
In the 1960s, the state government studied the feasibility of a highway around Kaena Point, which would be 6.7miles long. A rough road around the point, following a disused railroad, had already existed but was not suitable for most vehicle traffic.[2]
