national highway 1

This topic is esp to explain how Hawaii's highways are numbered? Hawaii has a very confusing numbering scheme, so this topic can be used to renumber or explain Hawaii's state highway system
Interstates (All on Oahu)
H-1 (Makakilo-Kahala) constructed 1953-1986
H-2 (Wahiawa-Waipahu) constructed 1976/77
H-3 (Halawa-Kaneohe MCBH) constructed 1972-1997
H-201 (Halawa-Kalihi) constructed from HI 78 1989, signed in 2004

had to make some changes to get the chart to display in a fixed-width font; otherwise its rendering defeats its purpose.  Please use the "code" IBB tag for further charts.  thanks!  :sombrero:

NOTE: if anybody has info about hawaii's highway network, post your knowledge on this forum
Oscar Voss' Hawaii Highways site http://www.hawaiihighways.com/ has info plus Steve Alpert's site  http://www.alpsroads.net/roads/hi/ has a wide range of assorted highways.

merged the two separate topics on the numbering into one single one.  Please continue with the other islands here in this one topic!

cool info!  What was H-1 numbered as between 1953 and 1957 or so?  Was it 99, or just named Kamehameha Hwy? 

also, do you happen to know when state highways were first signed in Hawaii?  I have seen this photo from 1943:



as well as another one showing this exact same gantry of an unknown date.  That has a primary defense route (shield shape) and a secondary one (raindrop shape), and ostensibly it was that exact same raindrop die that was used to stamp out the first set of state route markers.



that is the 1948 round fonts, and I have heard the system was first signed in 1956, with the last embossed cutouts being installed in 1968.  Is this correct?

one more thing to note about Hawaii routes: an older alignment of a road, if they want to keep a number on it, will tend to get a zero suffix.  For example, on Maui, there is 34, 340, and 3400, and on Oahu there is 75 and 750.



some of these roads are county routes, but they keep the state highway marker, except on Maui where they receive a variant of it with a different font, just as an implementation detail.

no, H-1 was numbered as HI 72 before the mid 1960s. When H-1 was introduced, HI 72 was truncated at Kahala & Moanalua Rd (now freeway- H-201) was renumbered HI 78 to Halawa. The rest, however, was renumbered HI 720 (since decommissioned) (according to Oscar Voss' Hawaii Highways site)

there are two remaining HI-72 shields that refer to that H-1 alignment.  Both are embossed cutouts.

Hawaii didn't have a route numbering system until just before statehood in 1959, except for the temporary route numbering system on Oahu established just before World War II (to keep troops from the mainland from getting lost -- Hawaiians didn't have much use for route numbers, and still don't), which fell into disuse until a completely new route number system was adopted in the 1950s for all the islands.  Most of Interstate H-1 was built after Hawaii got approval for its Interstate routes in 1960.  What was built pre-statehood (a short segment near the University of Hawaii's main campus) probably was signed as state route 72, if it ever had any non-Interstate route signage at all.

I don't know for sure when HDOT stopped using cutouts, but all of the ones I've seen carry route numbers from before the extensive renumbering done in 1968, so that would be my guess when the cutouts were replaced with the current style.

http://www.hawaiihighways.com/FAQs-page3.htm thoroughly covers route numbering in Hawaii.   The key things to remember are (1) route numbers are clustered by island, (2) two-digit routes are primary, and (3) three- and four-digit routes are secondary (for three-digit routes, and some four-digit routes, the first two digits indicate what, if any, primary route the secondary route is related to).

For example, Maui's Hana Highway starts off as route 36 (all Maui routes start with a "3"), then turns into route 360 right around where the speed limit drops to 15mph and the hairpin curves and one-lane bridges begin.  Similarly, route 377 and 378 are direct or indirect spurs or loops from route 37.  Except for the four-digit routes (which often seem random), a very logical system, which is odd for a state where (like Alaska) most people refer to non-Interstate highways by name rather than number.

so it is '59, not '56 for the first round-font raindrops?  That is indeed the oldest date stamp I have seen.  (In fact, the only date stamp that I recall!)



I wonder what the significance is of the second date-stamp and the designation "144A".  (The shield is a 144; a bit tough to read from the back.)

The 10.69 looks like it could be mileage.  The A could refer to direction.

it looks like a 10.63 to me, which implied a second date stamp... but yes, route, direction, and mileage makes a lot of sense.  The entire set of stamps looks to have been applied approximately at the same time, but in two or three distinct stampings.  (The left half is diagonal compared to the right half.)

I don't know when the new route numbers were posted pre-statehood; only that the Bureau of Public Roads started renumbering Hawaii's Federal-aid routes circa 1955 (before then, a disorganized mishmash of FA numbers), and the new FA numbers were soon thereafter used as the basis for how Hawaii highways got signed, showing up by the 1959 edition of one local street-level atlas.

"144" is most likely the route number used for part of present-day route 11 south of Hilo, back when the plan was to bypass that segment with a new road and move route 11 onto the new alignment.  The plan to build the new road, and number the existing road as 144 (though, at least initially, not to sign it as such), was developed in 1956.  The state gave up on that plan in 1963, and folded route 144's mileage into route 11.

national highway 1

the only route i remember being decommissioned in Hawaii was Route 90. It began at the south end of Ka'ena Point (western section of Farrington Hwy) and made its way down HI 93, then went along the Farrington along current 7110 & 7101 (both poorly signed; only mention is at Farrington/Fort Weaver Rd interchange & Waiawa (H-1/H-2/Kam Hwy/HI 99) interchange, then along current Kamehameha Hwy (HI 99; trailblazer installation @ Waimano Home Rd/fmr HI 73 intersection) then down to Pearl Harbor and along the Nimitz Hwy past Honolulu Airport to Dillingham Blvd (HI 7401) then Liliha St (HI 7413) and terminating at Vineyard Blvd (HI 98/fmr 72). A cutout that i saw on Oscar's site & AARoads:Hawaii:Miscellaneous Pictures shows a HI 90 shield. Plus a sign goof for exit 15 on H-1 westbound shows/ed a HI 90 shield. I believe that HI 90 was decommissioned c.1986 when the H-1 Airport Viaduct opened.

hmmm... looks like it could be Makakilo, Waianae, or Nanakuli. Probabaly the mountains and the 'lush vegetation' give it away a bit...

On Kauai, Highway 50 is usually referred to as Kaumualii Highway, while Highways 56 and 560 are both stretches of Kuhio Highway. Maluhia Road is Highway 520 through the famous "Tunnel of Trees," Koloa Road is Highway 530 and Highway 550 to Kokee is Waimea Canyon Road.

Like Maui's Hana Highway, the Kuhio Highway changes from a two-digit primary route to a three-digit secondary route, right about where the one-lane bridges start.  Route 50 goes through some name changes near its west end (and used to at its east end), but never changes to a secondary route.

520 (county), 530 (county), and 550 (state) are entirely secondary routes, with no related primary routes.
