World War II era Military and Hawaii Routes
« on: January 20, 2022, 03:32:22 PM »

If anyone has read any of the highway blogs on the O’ahu thread they probably have noticed the 1946 Army Day Map from Oscar’s page that I reference regarding World War II era Military and Hawaii Routes:


The Military Routes are US Route Shields whereas the Hawaii Routes are Spades I believe were likely supplied by the California Auto Clubs.  I had some observations based off looking at the Army Day Map:

-  Military Routes 1, 2 and 3 clearly are the most important highways.  They seem to function very similar to how Interstates H-1, H-2 and H-3 do today as being primary transportation corridors on O’ahu.
-  Military Routes 11, 12, 13, 16 and 17 are functionally the Secondary Tier of Primary Highways (example; Military Route 16 is aligned over the Old Pali Highway).  All the two digit Military Route connect to Military Route 1 (which circles O’ahu).  There is no Military Route 14 or 15 for reasons I can’t discern.
-  Some of the one and two digit Military Routes have spurs like Hawaii Route 12A.
-  The Hawaii Routes for the most part are in the 1XX, 2XX or 3XX ranges.  Overwhelmingly most connect to Military Routes 1-3 with some exceptions for the two digit Military Routes.  For the most part the number assignments seem to be sequential and/or clustered similar to hybrid or Washington and Nevada State Highway Numbering assignments. 

I don’t know, this seems like a really sound numbering system to me and well thought out.  I get that the 1955 System is based off Federal Aid Program assignments based in numbering ranges.  At first blush that’s a pretty decent system too until you get into overly recycled numbers and weird shit like 76 becoming 760 only to be reverted back to 76 later.
