Interstate H-1 (H-1) is the longest and busiest
Route description
H-1 begins near the Campbell Industrial Park in the town of
H-1 then continues along the northern edge of
Two miles (3.2 km) past the airport exit, three lanes exit the freeway at exit 18A to join Nimitz Highway toward Waikiki, while, half a mile (0.80 km) 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 72 (Kalanianaole Highway) ends.

History
This section needs additional citations for verification. (August 2016) |
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
Construction on the first new section of H-1 began in 1963, shortly after alignments were approved for most of the freeway.[6] The Lunalilo Freeway, already planned by the state government and funded with a 50-percent match from the federal government, was incorporated into plans for H-1 in 1965 following the rejection of five other proposed routings.[7][8] The westernmost section of H-1 in Makakilo opened on September 29, 1966.[9] The Kapiolani Interchange, opened in October 1967, filled a gap between two sections of the Lunalilo Freeway spanning three miles (4.8 km) in Honolulu.[10][11] Another gap in H-1 was filled in March 1969 with the opening of three miles (4.8 km) between Kunia Road (Route 76) and the Waiawa Interchange with H-2.[12]
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.[13] While the "Queen Liliʻuokalani" section of H-1 has signs designating it as such (one eastbound at exit 1, the other westbound after exit 19), there are no similar name signs for the Lunalilo Freeway portion (the remainder of the freeway).[14]
Interstate H-4

---|---|
Length | 6.5 mi (10.5 km) |
In the 1960s, a fourth freeway that would have been Interstate 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 6.5-mile-long (10.5 km) route of H-4 would have started at exit 18 (H-1/Nimitz Highway interchange) and followed the Honolulu waterfront to the Kapiolani interchange (exit 25B).[15] The idea, however, was unpopular and the freeway was never built.[14]
