A [[List of Hawaii state highways|system of state highways]] encircles each main island. Only O{{okina}}ahu has federal highways, and is the only area outside the contiguous 48 states to have signed [[Interstate Highway System|Interstate highways]]. Narrow, winding roads and congestion in populated places can slow traffic. Each major island has a public bus system.

[[Honolulu International Airport]] ([[International Air Transport Association airport code|IATA]]:{{spaces}}HNL), which shares runways with the adjacent [[Hickam Field]] (IATA:{{spaces}}HIK), is the major commercial aviation hub of Hawaii. The commercial aviation airport offers intercontinental service to North America, Asia, Australia and Oceania. [[Hawaiian Airlines]] and [[Mokulele Airlines]] use jets to provide services between the large airports in Honolulu, Līhu{{okina}}e, Kahului, Kona and Hilo. These airlines also provide air freight services between the islands. On May 30, 2017, the airport was officially renamed as the [[Daniel K. Inouye International Airport]] (HNL), after U.S. Senator [[Daniel Inouye|Daniel K. Inouye]].<ref>{{cite web|url=http://hidot.hawaii.gov/blog/2017/05/30/hawaiis-biggest-airport-officially-renamed-daniel-k-inouye-international-airport/|title=Department of Transportation—Hawaii's biggest airport officially renamed Daniel K.

The [[Hawaii Superferry]] operated between O{{okina}}ahu and Maui between December 2007 and March 2009, with additional routes planned for other islands. Protests and legal problems over environmental impact statements ended the service, though the company operating Superferry has expressed a wish to recommence ferry services in the future.<ref name="Alakai">{{cite news |newspaper=[[Honolulu Star-Bulletin]] |url=http://archives.starbulletin.com/content/20090329_Aloha_Superferry |title=Aloha, Superferry Alakai leaves Hawaii to find job |location=Honolulu, HI |publisher=[[Black Press|Black Press Group Ltd]] |issn=0439-5271 |id={{OCLC|9188300|433678262|232117605|2268098}} |date=March 29, 2009 |access-date=May 8, 2012 |archive-url=https://web.archive.org/web/20121013185707/http://archives.starbulletin.com/content/20090329_Aloha_Superferry |archive-date=October 13, 2012 |url-status=live }}</ref> Currently there is a passenger ferry service in [[Maui County]] between Lana{{okina}}i and Maui,<ref name="Lana'i Ferry">{{cite web |url= https://ssl.go-lanai.com/ |title= Expeditions: Maui—Lanaʻi Ferry Service |access-date= May 5, 2012 |archive-url= https://web.archive.org/web/20120509054306/https://ssl.go-lanai.com/ |archive-date= May 9, 2012 |url-status= live }}</ref> which does not take vehicles; a passenger ferry to Molokai ended in 2016.<ref>{{Cite web|url=https://www.mauinews.com/news/local-news/2016/10/molokai-ferry-ends-service-this-month/|title=Molokai ferry ends service this month &#124; News, Sports, Jobs—Maui News|access-date=October 28, 2019|archive-url=https://web.archive.org/web/20191028172749/https://www.mauinews.com/news/local-news/2016/10/molokai-ferry-ends-service-this-month/|archive-date=October 28, 2019|url-status=live}}</ref> Currently [[Norwegian Cruise Lines]] and [[Princess Cruises]] provide passenger cruise ship services between the larger islands.<ref name="NCL">{{cite web |url=http://www2.ncl.com/cruise-destination/hawaii/overview |title=Hawaii Cruises Cruise Overview &#124; Hawaii Cruises Cruise Destinations & Vacation Packages |website=Norwegian Cruise Line |location=Miami-Dade County, FL |access-date=May 5, 2012 |archive-url=https://web.archive.org/web/20120503161613/http://www2.ncl.com/cruise-destination/hawaii/overview |archive-date=May 3, 2012 |url-status=live }}</ref><ref name="Princess Cruises">{{cite web |url=http://www.princess.com/learn/destinations/hawaii/index.html |title=Hawaii, Tahiti, & South Pacific Cruises |website=Princess Cruises |location=Santa Clarita, CA |access-date=May 5, 2012 |archive-url=https://web.archive.org/web/20120505050333/http://www.princess.com/learn/destinations/hawaii/index.html |archive-date=May 5, 2012 |url-status=live }}</ref>

===Rail===
At one time Hawaii had a network of railroads on each of the larger islands that transported farm commodities and passengers. Most were {{RailGauge|3ft}} [[narrow gauge]] systems but there were some {{RailGauge|2ft6in}} gauge on some of the smaller islands. The standard gauge in the U.S. is {{RailGauge|4ft8.5in}}. By far the largest railroad was the [[Oahu Railway and Land Company]] (OR&L) that ran lines from Honolulu across the western and northern part of Oahu.<ref name="ReferenceA">{{cite book |title=Hawaiian Railway Album—WW II Photographs Vol 2 |author1=Norton Jr., Victor |author2=Treiber, Gale E. |year=2005 |publisher=Railroad Press |location=Hanover, PA}}</ref>

The OR&L was important for moving troops and goods during World War II. Traffic on this line was busy enough for signals to be used to facilitate movement of trains and to require [[wigwag (railroad)|wigwag]] signals at some railroad crossings for the protection of motorists. The main line was officially abandoned in 1947, although part of it was bought by the U.S. Navy and operated until 1970. {{convert|13|mi|km|spell=In}} of track remain; preservationists occasionally run trains over a portion of this line.<ref name="ReferenceA"/>

[[Skyline (Honolulu)|Skyline]] is an elevated passenger rail line operated by [[Honolulu Authority for Rapid Transportation|HART]], a semi-autonomous agency of the [[Honolulu County, Hawaii|City and County of Honolulu]]. It was built with the intention to relieve highway congestion.<ref>{{cite web |url=https://www.transit.dot.gov/sites/fta.dot.gov/files/docs/HI_Honolulu_HCT_Profile_FY17_0.pdf |title=High Capacity Transit Corridor Project: Honolulu, Hawaii |publisher= |date=December 2015 |access-date=26 June 2022}}</ref> A portion of Skyline opened for service in 2023, with the next phase expected to open in October 2025, and the final phase in 2031.<ref>{{Cite web |last1=Aquino |first1=Jamm |last2=Russell |first2=Cindy Ellen |date=2023-06-30 |title=Ridership commences on Honolulu's rail system |url=https://www.staradvertiser.com/2023/06/30/photo-gallery/ridership-commences-on-honolulus-rail-system/ |access-date=2023-07-02 |website=[[Honolulu Star-Advertiser]]}}</ref>
