'''Interstate&nbsp;H-1''' ('''H-1''') is the longest (27.16 miles = 43.71 km) 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.

==Route description==
[[File:Honolulu09.JPG|thumb|left|Aerial view of H-1 (looking east) from Daniel K. Inouye International Airport heading into Downtown Honolulu]]
H-1 begins near the Campbell Industrial Park in the town of [[Kapolei, Hawaii|Kapolei]]. West of this point, Route&nbsp;93 (Farrington Highway) continues toward [[Waianae, Hawaii|Waianae]]. The freeway continues east, passing the community of [[Makakilo, Hawaii|Makakilo]] until reaching the junction with [[Hawaii Route 750|Route&nbsp;750]] (north to [[Kunia Camp, Hawaii|Kunia Camp]]) and [[Hawaii Route 76|Route&nbsp;76]] (south to [[ʻEwa Beach, Hawaii|ʻEwa Beach]]).<ref name = maps/>

H-1 then continues along the northern edge of [[Waipahu, Hawaii|Waipahu]] approximately {{convert|3|mi|km|spell=in}} until its junction with [[Interstate H-2|H-2]]. It then continues east through the towns of [[Pearl City, Hawaii|Pearl City]] and [[Aiea, Hawaii|Aiea]] for approximately {{convert|5|mi|km|spell=in}} to the complex Halawa Interchange, where it meets [[Interstate H-3|H-3]] and [[Interstate H-201|H-201]]. The highway then turns south for {{Convert|2|mi|km|spell=in}}, then east soon after the exits for [[Hickam Air Force Base]] and [[Pearl Harbor]]. At this point, the highway runs along a viaduct above [[Hawaii Route 92|Route&nbsp;92]] ([[Nimitz Highway]]), passing to the north of [[Daniel K. Inouye International Airport]].<ref name=maps>[[Google Maps]] street maps and [[USGS]] [[topographic map]]s, accessed December 2007 via [http://mapper.acme.com/ ACME Mapper]</ref>

{{Convert|2|mi|km|spell=In}} past the airport exit, three lanes exit the freeway at exit&nbsp;18A to join Nimitz Highway toward [[Waikiki]], while, half a mile ({{Convert|0.5|mi|km|disp=output only}}) later, the remaining two lanes make a sharp turn south as H-1 reaches another major interchange with the east end of H-201. Access is provided by a left exit from H-1 east only. H-1 west does not have access to H-201 at this point.

From here, H-1 runs through the city of Honolulu along a series of underpasses and viaducts. A flyover interchange leading to [[Downtown Honolulu]] has a westbound exit and an eastbound entrance. H-1 ends in the Kāhala district of Honolulu near [[Kahala Mall]], where Route&nbsp;72 (Kalanianaole Highway) ends.

During morning commute hours on weekdays, an eastbound [[Contraflow lane|contraflow express lane]] is deployed from just east of exit&nbsp;5 to exit&nbsp;18A, where it connects to the beginning of the Nimitz Highway contraflow lane. The H-1 contraflow lane is often referred to as a "zipper lane" due to the use of a movable concrete barrier and a [[zipper machine]]. The H-1 and Nimitz Highway contraflow lanes are restricted to buses, motorcycles, and [[High-occupancy vehicle lane|high-occupancy vehicles]] with two or more occupants while in operation.

A set of Interstate Highways serving Oʻahu were authorized by the federal government in 1960, a year after Hawaii was admitted as a state. One of the corridors, connecting Barbers Point to Diamond Head, was designated as H-1 by the [[Bureau of Public Roads]] (now the [[Federal Highway Administration]]) on August 29, 1960.<ref name="FHWA-History">{{cite web |last=Weingroff |first=Richard |title=Interstates in Hawaii: ARE WE CRAZY??? |url=https://highways.dot.gov/highway-history/general-highway-history/rambler/ask-rambler-interstates-hawaii-are-we-crazy |work=Ask the Rambler |publisher=Federal Highway Administration |access-date=November 15, 2021}}</ref><ref>{{cite news |date=June 19, 1960 |title=Freeways To Be Extended |page=39 |work=The Honolulu Advertiser |url=https://www.newspapers.com/clip/88969133/freeways-to-be-extended/ |via=[[Newspapers.com]] |accessdate=November 15, 2021}}</ref> The portion of H-1 that runs through Downtown Honolulu had opened in 1953 as the Mauka Arterial and was incorporated into the new freeway. This section has been largely unchanged since its inception and its design suffers from having too many on/offramps, short distanced onramps, and onramps that enter the freeway almost immediately before an offramp (opposite of current design standards). The 'new' section of H-1 was, however, built to contemporary freeway standards.{{cn|date=November 2021}}

The Hawaiian Interstate shields have gone through several changes. Early shields contained the hyphen as per the official designation (e.g., H-1); however, these shields have been updated with the hyphen removed (e.g., H1). As in other states across the contiguous US, early Interstate shields also included the writing of 'Hawaii' above the Interstate route number and below the 'Interstate' writing.<ref>{{cite web |first= Oscar |last= Voss |date= June 2006 |title= Hawaii Road Sign Photos (Page 2 of 3) |url= http://www.hawaiihighways.com/hawaii-road-signs-page2.htm |work= Hawaii Highways |access-date= May 25, 2015}}{{self-published source|date=May 2015}}</ref> While the "Queen Liliʻuokalani" section of H-1 has signs designating it as such (one eastbound at exit&nbsp;1, the other westbound after exit&nbsp;19), there are no similar name signs for the Lunalilo Freeway portion (the remainder of the freeway).<ref name=interstate_guide>{{cite web |url=http://www.interstate-guide.com/i-h-001.html |work=Interstate-Guide |title=Interstate H-1 |access-date=November 24, 2010 |archive-date=June 22, 2011 |archive-url=https://web.archive.org/web/20110622033154/http://www.interstate-guide.com/i-h-001.html |url-status=dead}}{{self-published source|date=May 2015}}</ref>

In the 1960s, a fourth freeway that would have been '''Interstate&nbsp;H-4''' ('''H-4''') was proposed for the city of [[Honolulu]]. The intent of H-4 was to provide relief to the congested H-1 through [[Downtown Honolulu]]. Had it been built, the {{convert|6.5|mi|km|adj=mid|-long}} route of H-4 would have started at exit&nbsp;18 (H-1/Nimitz Highway interchange) and followed the Honolulu waterfront to the Kapiolani interchange (exit&nbsp;25B).<ref>{{cite report |date=October 1968 |title=Proposed Route H-4, Interstate and Defense Highway System Extension |publisher=State of Highway Department of Transportation |url=http://www.hawaiihighways.com/proposed-Interstate-H4-report.pdf |access-date=August 7, 2016}}</ref> The idea, however, was unpopular and the freeway was never built.<ref name=interstate_guide/>
