INTERSTATE H-201

'Interstate H-201' ('H-201') is a tertiary intrastate Interstate highway located on the island of O‘ahu in the U.S. state of Hawaii. The H-201 is also known as the 'Moanalua Freeway'. The 4-mile loop route connects exits 13 and 19 on Interstate H-1, passing Fort Shafter, Tripler Army Medical Center, and Red Hill.
Despite being designated an Interstate in 1989, until recently the route was a "hidden" Interstate signed only as 'Route 78'. Interstate signs started appearing in mid-2004. The section of the Moanalua Freeway between Route 99 (Kamehameha Highway) and the western Interstate H-1 interchange remains designated as Route 78.

History

Major cities 'Bolded cities' are officially-designated control cities for signs

The Federal Highway Administration approved the addition of Interstate H-201 to the Interstate Highway System on November 1, 1989. The Hawai‘i Department of Transportation asked that the Moanalua Freeway be reclassified as an Interstate so that the interchange with H-1 at the eastern end could conform to federal highway standards. At first, the highway was initially designated H-1A, but federal highway policy does not allow alphabetic suffixes in Interstate numbers. The final designation, H-201, conforms to the general rules for three-digit Interstate "loop" routes.
Until 2004, the state Department of Transportation chose not to sign H-201 as such, instead retaining the designation Route 78. Reasons given included:

★ inability to render the new route number in a legible manner (it is necessary to use the thinnest font to render the number, as seen above)

★ encouraging motorists to use the newer and better designed H-1

★ avoiding confusion with Interstate H-2
In July 2004, in conjunction with a major resurfacing of both sides of the freeway, it was decided to bring the signage in line with the official designation.
