Interstate H1 / Lunalilo Freeway / Queen Liliuokanai Freeway
Hawaii's oldest and most congested freeway, H-1 is the primary freeway along the south shore of Oahu. Beginning at the former Barbers Point NAS and Ewa plantation, it proceeds east around Pearl Harbor, dives south to serve Honolulu International Airport, then east through densely populated Honolulu and north of Waikiki Beach, to end short of Koko Head.
Portions of H-1 predate statehood, as an upgrade of Lunalilo Street, the freeway's namesake. The oldest section, from Punahou street east to King Street (Exits 23-25), was open before 1959. Originally signed as Hawaii 72, this section shows its age today, as it resembles freeways in downtown Los Angeles more than a present-day freeway.
H-1 is notoriously congested at all hours of the day, with little to no room for expansion. Hawaii DOT has some unique features on the western segment, including an HOV lane during morning rush hour where two westbound lanes are converted into an eastbound HOV lane. Some sections have been widened as time permits, but with the rapid growth of the Ewa area as a bedroom community for Honolulu, traffic will probably continue to worsen as time goes on.

The following timeline shows the general construction of Hawaii 72, later renumbered as H-1.
- 1953. First section of the Mauka Arterial opened. The Mauka arterial was approximately a mile section around University Avenue, present-day Mile 24.
- 1959. At statehood, the first section of what is now called the Lunalilo Freeway open between Punahou Street (Mile 23) and King Street (Mile 25). Maps show a proposed route from Punahou Street west to Middle Street (present H-1/H-201 interchange).
- 1960. Freeway extended west to Ke'eaumoku Street (approximately 1/2 mile west of Punahou Street). A section of present-day H-201 opened thru Fort Shafter, signed as Hawaii 72. Sections from Fort Shafter east to Houghtailing Street (Exit 20B) and the Pali Highway interchange (exit 21A/B) under construction.
- 1961. Open sections are Pu'uloa Road (present-day H-201) to Houghtailing Street (Exit 20B), the Pali Highway interchange, and Ke'eaumoku Street to King Street.
- 1964. The section from Kapahulu Street (Mile 25) east to Koko Head Ave (Exit 26A) under construction.
- 1965. Kapahulu Street to Koko Head Ave open. There is a gap in existing freeway sections between King Street and Kapahulu Street; this short 1/2 mile section is under construction.
- 1967. H-1 first appears on maps, cosigned with Hawaii 72. The freeway is continuous from Pu'uloa Road east to Pele Street (just east of Pali Highway, Hawaii 61), as well as the existing sections from Ke'eaumoku Street to King Street and Kapahulu Street to Koko Head Ave. The western section between Kunia Road and Kamehameha Highways (Exits 5 through Exit 8A) is open, with the section between Miles 0 and 5 under construction.
- 1968. The gap between King Street and Kapahulu Street is opened. H-1 is extended east to its present terminus east of Kilauea Ave. There is still a gap between Pele Street and Ke'eaumoku Street.
- 1972. H-1 is open from Kamehameha Highway (Western terminus) to Kaimakani Street, immediately west of the Halawa interchange. The Hawala interchange and sections of H-1 to Middle Street are proposed. From Middle Street east to Kilauea Ave is completed freeway. Hawaii 72 is trunced at the eastern end of H-1; the orphaned section between Pu'uloa Road and Middle Street is re-signed as Hawaii 78.
- 1986. H-1 is completed between Nimitz Highway and Middle Street (Miles 18-19), completing H-1. The through lanes of H-1 east use the Middle Street tunnel, completed in 1961 for the Middle Street off-ramp.
