Routes in Hawaii

Below is a partial list of state highways in Hawai‘i.

The current state (then territorial) highway numbering system was established in 1955. Route numbers are organized so that the initial digit corresponds to the island:

In general, two-digit numbers are primary highways, while secondary state highways are given three-digit numbers.

When referring to highways, Hawai'i residents usually refer to state highways by their names instead of their route numbers (e.g. Kamehameha Highway instead of Route 99).

The designations of Interstate highways in Hawai‘i are abbreviated using the "H" prefix instead of the "I" prefix (e.g. Interstate H-1 is called simply "H-1" for short, NOT "I-H-1").

Though marked with U.S. Route shields, these routes were not actual U.S. Routes. They were used to assist military personnel not accustomed to the Hawaiian street names during the time of Martial law in the Territory of Hawai‘i from 1941 to 1945. [1]
