Even though there is no causeway from the Islands to the mainland to make them true interstate (between states) highways, the H-1, H-2, and H-3 are considered interstate highways. They were built as parts of the Eisenhower Interstate System (1956). Like the rest of the System, they were built to facilitate military transportation in times of emergency. The H-2 connects Pearl Harbor with Schofield Barracks, while the H-3 connects Pearl Harbor with the Kaheohe Marine Corps Base. The following pages provide interesting historical information and photographs about the three intrastate members of the interstate highway system:
H-1. Liliuokalani Freeway and Lunalilo Freeway
The H-1 began life before statehood as the Mauka Arterial.
After 1959, it was extended so that, today, it runs from Nanakuli in the west
to Kahala in the east. It ends at the Kilauea Avenue overpass. Beyond that, the highway is known as the Kalaniana'ole Highway (Route 72) and is simply a divided highway with traffic signals and open access.

Because the H-1 turns south to pass the airport and Pearl Harbor before rising again to continue its westward trek, a connecting highway was built across the top of that dip that became the Moanalua Freeway (H-201).

The H-2 runs from the H-1 at the Aloha Stadium north to Schofield Barracks in Wahiawa. The H-201 runs from the Nimitz Highway at the H-1 turnoff to the Aloha Stadium, where it rejoins the H-1 for the trek on to Nankuli. For reasons unknown, the author of these links put both highways on the same page.

It should be noted that the H-3 competes with I-70 through
Glenwood Canyon in Colorado as being the most scenic, expensive, and technically
difficult (to design and build) stretches of the Eisenhower Interstate System.
Because of its route through cultural and religious sites, it is the most
controversial part of the system, as well.
