Routes in Hawaii

Interstate H-1 (abbreviated H-1) is the busiest Interstate Highway in the US state of Hawaii. The highway is 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 Route 93 (Farrington Highway) in Kapolei to Route 72 (Kalanianaole Highway) in Kāhala. 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 Liliʻuokalani Freeway; this name is shown on some roadmaps. It is both the southernmost and westernmost signed Interstate Highway in the United States.

Interstate H-1 begins near the Campbell Industrial Park in the town of Kapolei, Hawaii. West of this point, Hawaii State Route 93 (Farrington Highway) continues toward Waianae. The freeway continues east, passing the community of Makakilo until reaching the junction with SR 750 (north to Kunia) and SR 76 (south to Ewa Beach).

H-1 then continues along the northern edge of Waipahu approximately 3 miles (4.8 km) until its junction with Interstate H-2. It then continues east through the towns of Pearl City and Aiea for approximately 5 miles (8.0 km) to the complex Halawa Interchange, where it meets Interstates H-3 and H-201. The highway then turns south for two miles (3 km), then east soon after the exits for Hickam Air Force Base and Pearl Harbor. At this point, the highway runs along a viaduct above State Route 92 (Nimitz Highway), passing to the north of Honolulu International Airport.
