Hawaii Route 93

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.

Route description
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.

History
In the 1960s, the state government studied the feasibility of a highway around Kaena Point, which would be 6.7 mi long. A rough road around the point, following a disused railroad, had already existed but was not suitable for most vehicle traffic.
