Despite the number, this is an east-west highway&mdash;the 'H'-series (for Hawaii) numbering reflects the order in which routes were funded and built. H-1 goes from [[Hawaii Route 93|Route 93]] (Farrington Highway) in [[Kapolei, Hawaii|Kapolei]] to [[Hawaii Route 72|Route 72]] (Kalanianaole Highway) in [[Honolulu, Hawaii|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 '''[[Liliʻuokalani|Queen Liliʻuokalani]] Freeway'''; this name is shown on some roadmaps. It is the westernmost interstate highway in the United States. ==Route description== [[Image:H1 freeway lapse.jpg|thumb|left|Time-lapse image of H-1 near Ward Avenue.]] 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, Hawaii|Waianae]]. The freeway continues east, passing the community of [[Makakilo, Hawaii|Makakilo]] until reaching the junction with SR 750 (north to Kunia) and SR 76 (south to [[Ewa Beach, Hawaii|Ewa Beach]]).<ref name=maps>[[Google Maps]] street maps and [[USGS]] [[topographic map]]s, accessed December 2007 via [http://mapper.acme.com/ ACME Mapper]</ref> H-1 then continues along the northern edge of [[Waipahu, Hawaii|Waipahu]] approximately 3 miles until its junction with [[Interstate H-2]]. It then continues east through the towns of [[Pearl City, Hawaii|Pearl City]] and [[Aiea, Hawaii|Aiea]] for approximately 5 miles to the complex Halawa Interchange, where it meets Interstates [[Interstate H-3|H-3]] and [[Interstate H-201|H-201]]. The highway then turns south for two miles, 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]].<ref name=maps>[[Google Maps]] street maps and [[USGS]] [[topographic map]]s, accessed December 2007 via [http://mapper.acme.com/ ACME Mapper]</ref> {| class="infobox" width="230px" !style="background: #ccf;"|<big>Major cities</big><br><small>'''Bolded cities''' are officially-designated [[control city|control cities]] for signs</small> |- | *'''[[Waianae, Hawaii|Waianae]]''' (via [[Route 93 (Hawaii)|Route 93]]) *'''[[Honolulu, Hawaii|Honolulu]]''' |} [[Image:Interstate H-1.jpg|thumb|left|H-1 eastbound into Honolulu.]] Two miles past the airport exit, three lanes exit the freeway at exit 18A to join Nimitz Highway toward Waikiki, while the remaining two lanes make an S-curve to join the east end of [[Interstate H-201]]. From here H-1 runs through the city of Honolulu along a series of underpasses and viaducts. H-1 ends in the Kahala district of Honolulu near Kahala Mall, where state route 72 (Kalanianaole Highway) ends. [[Image:Honolulu09.JPG|thumb|Aerial view of H-1 (looking east) from Honolulu Airport heading into downtown Honolulu.]] H-1 has a maximum posted speed limit of 60 mph (100 km/h) west of the Kunia-Ewa-Waipahu interchange; a 55 mph (90 km/h) speed limit for the remaining section running to the airport, and a 50 mph (80 km/h) speed limit on the Lunalilo freeway section that runs within the Honolulu area, with a few 45 mph (73 km/h) sections. ==History== 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. This section has been largely unchanged since its inception and its design suffers from having too many on/off ramps, short distanced on-ramps, and on-ramps that enter the freeway almost immediately before an off-ramp (opposite of current design standards). The 'new' section of H-1 was, however, built to modern freeway standards. ==Exit list== {| class=wikitable !County !Location !Mile<ref name=Delorme>{{cite map|title=Street Atlas USA|publisher=[[Delorme]]|year=2007|edition=Toggle Measure Tool|accessdate=2007-06-03}}</ref> ![[Exit number|#]] !Destinations !Notes |- |rowspan=49|[[Honolulu County, Hawaii|Honolulu]] |rowspan=4|[[Kapolei, Hawaii|Kapolei]] |0.00 | |{{jct|state=HI|Route|93|dir1=west|name1=[[Farrington Highway]]}} |Westbound exit and eastbound entrance; west end of H-1 |- |1.12 |1A |[[Campbell Industrial Park]], [[Barbers Point Harbor]] ([[Route 95 (Hawaii)|Route 95]]) |Signed as exit 1 westbound |- |1.18 |1B |[[Makakilo, Hawaii|Makakilo]], [[Kapolei, Hawaii|Kapolei]], [[Kalaeloa, Hawaii|Kalaeloa]] |Eastbound exit and westbound entrance |- |2.21 |2 |[[Makakilo, Hawaii|Makakilo]], [[Kapolei, Hawaii|Kapolei]], [[Kalaeloa, Hawaii|Kalaeloa]] ([[Route 901 (Hawaii)|Route 901]]) |Westbound exit and eastbound entrance |- |rowspan=5|[[Waipahu, Hawaii|Waipahu]] |6.49 |5 |{{jct|state=HI|Route|76|dir1=south|Route|750|dir2=north|city1=Kunia|city2=Waipahu|city3=Ewa}} |Signed as exits 5A (south) and 5B (north) westbound |- |8.20 |7 |[[Waikele, Hawaii|Waikele]], [[Waipahu, Hawaii|Waipahu]] | |- |9.40 |8 |{{jct|state=HI|Route|99|dir1=north|name1=[[Kamehameha Highway]]|city1=Waipahu|city2=Pearl City}} |Eastbound exit and westbound entrance; signed as exits 8A (south) and 8C (north) |- |9.74 |8B |{{jct|state=HI|I|2|dir1=north|city1=Mililani|city2=Wahiawa}} |Signed as exit 8A westbound |- | |8B |[[Waipahu, Hawaii|Waipahu]] ([[Route 7101 (Hawaii)|Route 7101]]) |Westbound exit and eastbound entrance |- |[[Pearl City, Hawaii|Pearl City]] |11.62 |10 |[[Pearlridge, Hawaii|Pearlridge]], [[Pearl City, Hawaii|Pearl City]], [[Waimalu, Hawaii|Waimalu]] | |- |rowspan=3|[[Halawa, Hawaii|Halawa]] |14.20 |13A |{{jct|state=HI|Route|78|dir1=west|city1=Aiea|city2=Pearlridge}} | |- |14.61 |13B |{{jct|state=HI|I|3|dir1=east|I|201|dir2=east|city1=Kaneohe|city2=Honolulu}} |Signed as 13A eastbound |- | |13B |[[Halawa Heights, Hawaii|Halawa Heights]], [[Aloha Stadium]] ([[Route 7241 (Hawaii)|Route 7241]]) |Eastbound exit and westbound entrance |- |rowspan=30|[[Honolulu, Hawaii|Honolulu]] |16.65 |15A |{{jct|state=HI|Route|99|dir1=west|city1=Arizona Memorial}}, [[Aloha Stadium]] |Westbound exit and eastbound entrance |- |16.85 |15B |{{jct|state=HI|Route|92|dir1=west|city1=Hickam AFB|city2=Pearl Harbor}} |Signed as 15 eastbound |- |16.06 |15 |{{jct|state=HI|Route|92|dir1=east|name1=[[Nimitz Highway]]}} |Eastbound exit and westbound entrance |- |17.77 |16 |[[Honolulu International Airport]] | |- |19.60 |18 |{{jct|state=HI|Route|92|dir1=west|name1=[[Nimitz Highway]]}} |Westbound exit and eastbound entrance |- |19.12 |18A |{{jct|state=HI|Route|92|dir1=east|name1=[[Nimitz Highway]]|city1=Waikiki}} |Eastbound exit and westbound entrance |- |19.34 |18B |Middle Street, Dillingham Boulevard ([[Route 7415 (Hawaii)|Route 7415]]) |Eastbound exit and westbound entrance |- |20.36 |19A |Middle Street ([[Route 7415 (Hawaii)|Route 7415]]) |Westbound exit only |- |20.36 |19B |{{jct|state=HI|I|201|dir1=west|city1=Fort Shafter|city2=Aiea}} |Westbound exit and eastbound entrance |- |20.56 |20A |{{jct|state=HI|Route|63|dir1=north|name1=[[Likelike Highway]]}} | |- | |20B |Houghtailing Street |Westbound exit only |- |20.80 |20B |{{jct|state=HI|Route|98|dir1=east|name1=Vineyard Boulevard}} |Eastbound exit and westbound entrance |- |21.35 |20C |Palama Street |Westbound exit only |- | |21A |School Street |Westbound exit and eastbound entrance |- |22.31 |21A |{{jct|state=HI|Route|61|name1=[[Pali Highway]]}} |Signed as exit 21B westbound |- |22.77 |21B |Punchbowl Street |Eastbound exit and westbound entrance |- | |22 |{{jct|state=HI|Route|98|dir1=west|name1=Vineyard Boulevard}} |Westbound exit and eastbound entrance |- |23.10 |22 |Kinau Street |Eastbound exit and entrance |- | |23 |Lunalilo Street |No eastbound exit |- |24.06 |23 |Punahou Street |Eastbound exit and westbound entrance |- |25.07 |24A |Bingham Street |Eastbound exit and westbound entrance |- | |24A |Wilder Avenue |Westbound exit only |- |25.30 |24B |University Avenue | |- |25.62 |25A |King Street - [[Waikiki, Hawaii|Waikiki]], [[Honolulu Zoo]] | |- | |25B |Kapiolani Boulevard |Westbound exit and eastbound entrance |- |26.10 |25B |6th Avenue |Eastbound exit and westbound entrance |- |26.83 |26A |Koko Head Avenue |Eastbound exit and westbound entrance |- |27.53 |26B |Waialae Avenue |Signed as exit 26 westbound |- |28.16 |27 |Kilauea Avenue |Westbound exit and eastbound entrance |- | | |{{jct|state=HI|Route|72|dir1=east|name1=[[Kalanianaole Highway]]}} |Eastbound exit and westbound entrance; east end of H-1 |} ==Auxiliary routes== *A portion of the '''Moanalua Freeway''' is designated as [[Interstate H-201]].
