Former Hawaii Route 232 (old Hawaii Route 19 on Mamalahoa Highway in Ookala)


Hawaii Route 232 was a portion of the original routing of Hawaii Route 19 along Mamalahoa Highway in the community of Ookala.  Hawaii Route 19 moved to the grade of the Hawaii Consolidated Railway which bypassed Ookala during late 1950s.  Old Mamalahoa Highway was reactivated during the early 1960s as Hawaii Route 232 to provide a state highway corridor to the community business district.  Ultimately this corridor was short lived as it was recommended for deletion in 1967.

The history of Hawaii Route 232

Ookala was established in as a siding of the Hawaii Consolidated Railway Hamakua Division.  Much of Mamalahoa Highway on the Hamakua Coast of the Big Island acted as frontage of the Hawaii Consolidated Railway Hamakua Division.  The railroad took the best grade alignments possible north from Hilo to Paaulio.  The first phase of the Hamakua Division opened between Hilo and Hakalau by 1911.  The line was extended north to Paaulio by 1913.  The Hamakua Division was an impressive effort which required installation of 35 bridges and 3 tunnels.  

Mamalahoa Highway was declared by royal decree in 1783 via the Law of the Splintered Paddle.  The law was conceived based off an incident Kamehameha I was part of along the Puna coast.  During said incident Kamehameha I and his men were conducting a shoreline raid when they encountered two Puna fisherman.  While pursuing the fisherman across a lava field one of Kamehameha's feet was caught in a rock.  The fishermen seized upon the opportunity to retaliate and struck Kamehameha in the head with a wooden paddle. 

Kamehameha opted to not retaliate against the fisherman and used the incident as the basis of the Law of the Splintered Paddle.  The law essentially guaranteed safe passage to all travelers across the Hawaiian Islands and was used as a basis of Mamalahoa Highway on the Big Island.  The highway corridor was rapidly developed across the Big Island and was mostly annexed as early automotive roads.  

Ookala can be seen along the Mamalahoa Highway and Hamakua Division on the 1915 United States Geological Survey map of Hamakua.  


Much of the Hamakua Division was destroyed by a tsunami on April 1, 1946.  The division was abandoned by the Hawaii Consolidated Railway during December 1946.  Sugar plantation owners attempted to repurpose intact portions of the line north of the Wailuku River, but all were also abandoned by late 1948.  

One of the first portions of the Hamakua Division to be repurposed as part of a realigned Mamalahoa Highway came in 1950.  During said year the right-of-way in Hilo was used as the basis for Bayfront Highway.  The Wailuku River Bridge piers were reused for construction of a new highway bridge which removed significant amounts of traffic north/south from downtown Hilo.  

In 1955 the Hawaii Route System was modified and expanded to the Big Island.  The northern half of Mamalahoa Highway from Kailua-Kona to Hilo was assigned Hawaii Route 19.  The early routing of Hawaii Route 19 can be seen on the 1959 Gousha Map of Hawaii.  As originally configured Hawaii Route 19 began at Hawaii Route 11 at the intersection of Kaukina Highway/Palani Road in Kailua-Kona and ended at Hawaii Route 12 at the intersection of Kamehameha Avenue/Kanoelehua Avenue in Hilo.


Early Hawaii Route 19 was carried through Ookala via Mamalahoa Highway.  The current alignment can be seen under construction in Ookala following the grade of Hamakua Division on the 1957 United State Geological Survey map of Kukaiau.  The modern alignment of Hawaii Route 19 in Ookala is a divergence of the Hamakua Division grade as it strays south of the community.  


The final segment of the Old Mamalahoa Highway on the northern side of the Big Island and Hamakua Coast was replaced with a modern highway in September 1963.  Mamalahoa Highway within Ookala was reactivated as the 0.9-mile Hawaii Route 232 during the early 1960s.  This designation more or less provided a direct Hawaii Route connection to central business district of Ookala.  Ultimately Hawaii Route 232 was short lived as it was recommended for deletion in a 1967 Hawaii Department of Transportation document.

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926.  Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California.  The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant.  However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices.  This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes.  The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield.  In the background Mount Whitney can be seen in the Sierra Nevada range.   ...

May 2023 Ontario Trip (Part 3 of 3)

  Over the years, I have made plenty of trips to Ontario, crisscrossing the southern, central and eastern parts of the province. Living in Upstate New York, it's pretty easy to visit our neighbor to the north, or is that our neighbor to the west? Ottawa is one of my favorite cities to visit anywhere in the world, plus I've discovered the charm of Kingston, the waterfalls of Hamilton (which is on the same Niagara Escarpment that brings us Niagara Falls), the sheer beauty of the Bruce Peninsula, and more. But I hadn't explored much of Cottage Country. So I decided to change that, and what better time to go than over Memorial Day weekend, when the daylight is long and I have an extra day to explore. On the third and final day of my trip, I started in Huntsville and made my way through Muskoka District and Haliburton County, passing by many lakes along the way. I stopped in towns such as Dorset, Haliburton and Bancroft before making a beeline down to Belleville and then over th...

Ghost Town Tuesday; Nichols, FL

A couple years ago I spent a lot of spare time exploring phosphate mining ghost towns in the Bone Valley of Polk County, Florida.  One ghost town in particular called Nichols on Polk County Route 676 west of Mulberry caught my eye due to a relative lack of documentation on ghosttowns.com. Nichols was created in 1905 during the early phosphate mining boom in the Bone Valley region.  For the time Nichols was unusual since it had company housing in the Nichols Mine site and private residences outside the gate.  Nichols is only about two miles west of Mulberry which probably made it a somewhat reasonable commute even by the wonky standards of the early 20th Century.  Most of the Bone Valley region was relatively remote which made commuting or homesteading impractical which is why there are so many ghost towns in the area.  The company housing section of Nichols was phased out and abandoned by 1950. The Nichols town site is largely abandoned and could "possibl...
