Hawaii Route 750 Kunia Road (former Hawaii Route 75)

By

Hawaii Route 750 is an 8.1-mile State Highway located on the Island of O'ahu.  The entirety of Hawaii Route 750 is aligned Kunia Road from Interstate H-1/Hawaii Route 76 in Waipahu north to Hawaii Route 99 in the grounds of Wheeler Army Airfield.  Hawaii Route 750 was previously designated as Hawaii Route 75.  

This page is part of the Gribblenation O'ahu Highways page.  All Gribblenation and Roadwaywiz media related to the highway system of O'ahu can be found at the link below:

Part 1; the history of Hawaii Route 750

Kunia Road takes its name from the former Del Monte Planation Kunia Camp.  Kunia Camp began operations in 1916 and ultimately shuttered as of 2007.  More regarding the former Del Monte Planation facilities can be viewed on historichawaii.org at their Kunia Camp page. 

Prior to the Statehood the first signed highways within Hawaii Territory came into existence during World War II.   During World War II the territory of Hawaii saw an influx of military activity following the attack on Pearl Harbor on December 7th, 1941.  Numerous Military Routes and early Hawaii Routes were signed through the Hawaiian Territory to aid military personnel in navigating the islands.  Military Highways were assigned US Route style shields whereas lesser highways were assigned an early variation of what is now the Hawaii Route Spade.  Kunia Road can be seen assigned as Military Route 3 given it terminated at Wheeler Army Airfield and near the Schofield Barracks.  A full version of the 1946 Army Map of O'ahu can be seen on hawaiihighways.com here.  


Circa 1955 following the conclusion of World War II the United States Bureau of Public Roads renumbered the Hawaii Route System.  The 1955 Hawaii Route Renumbering saw most of the conventions utilized by the current Hawaii State Route System established.  Primary Hawaii Routes were given two digit numbers whereas Secondary Hawaii Routes were given three digit numbers.  The Hawaii Routes were assigned in sequence for what Island/County they were located on coupled with what Federal Aid Program number they were tied to.  In the case of O'ahu the Island was assigned numbers in the range of 60-99.  In the case of Kunia Road it was assigned as part of Hawaii Route 75.  A far more detailed explanation of the 1955 Hawaii Route Renumbering can be found at hawaiihighways.com here. 

Hawaii Route 75 can be seen aligned on Kunia Road on the 1959 Gousha Map of Hawaii. 

On August 21st, 1959 Hawaii became the 50th State which saw its profile rise significantly.  The Hawaii Department of Transportation's History of Interstate H-3 guide details much of the early history of the Interstate System in Hawaii.  The Interstate System in Hawaii was authorized as part of the 1960 Statehood Act.  The 1960 Statehood Act authorized Interstates H-1, H-2 and H-3 on the Island of O'ahu.   


Interstate H-2 was meant to serve as a limited access replacement to Hawaii Route 75/Kunia Road and Hawaii Route 99/Kamehameha Highway in the Waipahu-Wheeler Army Airfield corridor.  Unlike the other Interstate corridors of O'ahu Interstate H-2 was relatively uncontroversial and three general routing options were discussed via public hearing during October 1962.  Construction of the Wahiawā Interchange would begin during 1971.  The first two northbound miles of Interstate H-2 opened to traffic from Interstate H-1 to Mililani Cemetery on October 3rd, 1974.  The opening ribbon cutting ceremony of the first two miles of Interstate H-2 can be seen in the October 4th, 1974 Honolulu Advisor.  


The remaining portion of Interstate H-2 north to Wahiawā opened on February 21st, 1977.  The opening ceremony for the completed Interstate H-2 was announced in the February 16th, 1977 Honolulu Advisor.  


Upon the completion of Interstate H-2 the corridor of Hawaii Route 75 on Kunia Road was designated as Hawaii Route 750.  The three digit "750" denoted Kunia Road was now a secondary State Highway.  Hawaii Route 750 was truncated slightly during 1982 from Farrington Highway north to Interstate H-1 when Hawaii Route 76 was relocated off what is now Old Fort Weaver Road.  Hawaii Route 750 can be seen on the 1983 USGS Map of Wheeler Army Airfield.

Chowchilla Mountain Road to Yosemite National Park

By
Chowchilla Mountain Road of Mariposa County is one of the oldest roadways servicing Yosemite National Park.  As presently configured this fourteen-mile highway begins at California State Route 49 near Elliot Corner and terminates at the Wawona Road in Yosemite National Park.  Chowchilla Mountain Road was constructed as a franchise toll road over Battalion Pass circa 1869-1870.  The highway was built at behest of Galen Clark to connect the town of Mariposa to his property near the South Fork Merced River at what is now Wawona.   In late 1874 the highway along with Clark’s Station would be purchased by the Washburn Brothers.  The Washburn Brothers would continue to toll Chowchilla Mountain Road as part of their Yosemite Stage Route lines.  The highway would ultimately become a Mariposa County public highway in 1917.  Mariposa would later be more directly linked with Yosemite Valley in 1926 following the completion of the Yosemite All-Year Highwa...

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

By
In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l...

Angus L. Macdonald Bridge

By
At 1.3 kilometers (or about 0.84 miles) in length, the Angus L. Macdonald Bridge is one of two bridges crossing over the Halifax Harbour between Halifax, Nova Scotia and Dartmouth, Nova Scotia, with the other bridge being the A. Murray Mackay Bridge . Opened in 1955 and named after former Nova Scotia Premier and Canadian Minister of Defense for Naval Services Angus L. Macdonald, the Macdonald Bridge was the first bridge that crossed Halifax Harbour that was opened to traffic. The Macdonald Bridge was also the subject of the Big Lift, which was only the second time in history that the span of a suspension bridge were replaced while the bridge was open to traffic. Planning began in 2010 for the Big Lift, while construction took place between 2015 and 2017. Similar work occurred on the Lion's Gate Bridge in Vancouver, British Columbia before the project took place on the Macdonald Bridge. At this time, much of the bridge infrastructure is new, leaving only the towers, main cables and...
