Routes in Hawaii

Interstate H-201 (H-201) is an auxiliary 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 (6.4 km) 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. Because this roadway was formerly an unsigned Interstate designation, it was commonly thought to be the only segment of freeway in Hawaii to not have an Interstate designation.

History

The length of H-201 was originally designated as Route 78.[2]

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. 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 the following:

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.
