Interstate H-1 (abbreviated H-1) is the busiest interstate highway in Hawaii, United States, located on the island of O‘ahu. Despite the number, this is an east-west highway—the 'H'-series (for Hawaii) numbering reflects the order in which routes were funded and built. H-1 goes from Kapolei at Hawai‘i State Rte. 93 (Farrington Highway) to Kāhala at State Rte. 72 (Kalanianaole Highway).

East of Middle Street in Honolulu (exit 19A), H-1 is also known as the Lunalilo Freeway and is sometimes signed as such at older signs in central Honolulu. West of Middle Street, H-1 is also known as the Queen Liliuokalani Freeway; this name is shown on some roadmaps. It is the westernmost interstate highway in the United States.

A portion of the Moanalua Freeway is designated as Interstate H-201. Until mid-2004, it was signed as Hawaii State Route 78.

[edit] Notes

This was the first freeway of any kind built in the Hawaiian Islands. The portion of H-1 that runs through downtown Honolulu opened in 1953 as the Mauka Arterial; it was added to the Interstate system when Hawaii became a state.
