'''Interstate&nbsp;H-1''' ('''H-1''') is the longest (27.16 miles = 43.71km) and busiest [[Interstate Highway]] in the US state of [[Hawaii]]. The highway is located on the island of [[Oʻahu]]. 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 [[Hawaii Route 93|Route&nbsp;93]] (Farrington Highway) in [[Kapolei, Hawaii|Kapolei]] to [[Hawaii Route 72|Route&nbsp;72]] (Kalanianaole Highway) in [[Kāhala, Hawaii|Kāhala]]. East of Middle Street in [[Honolulu]] (exit&nbsp;19A), H-1 is also known as the Lunalilo Freeway, after [[Lunalilo|the former Hawaiian king]], 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, after [[Liliʻuokalani|the former Hawaiian queen]]; this name is shown on some roadmaps. It is both the southernmost and westernmost signed Interstate Highway located in the US.
