Interstate H-2

Interstate H-2 is a 8.33 mile freeway which runs the north/south on the Hawaiian Island of O'ahu.  Interstate H-2 begins from the terminus of Interstate H-1 in at Pearl City and treks northward to a terminus at Hawaii Route 99 in Wahiawā.  Interstate H-2 is the primary highway connecting Naval Station Pearl Harbor to Wheeler Army Airfield.  Pictured above is Interstate H-2 southbound beginning in Wahiawā.

Part 1; the history of Interstate H-2

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.  

A 1946 Army Map of the Island of O'ahu shows the primary road between Pearl City Wahiawā as part of Military Route 1 which was signed on the Kamehameha Highway.  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 the Kamehameha Highway in the Pearl City-Wahiawā corridor it was assigned part of Hawaii Route 99.  A far more detailed explanation of the 1955 Hawaii Route Renumbering can be found at hawaiihighways.com here.

On August 21st, 1959 Hawaii became the 50th State which saw it's profile rise significantly.  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.

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.  


Interstate H-2 originally opened with Bus Lanes which were turned into High Occupancy Use by 1979.  Since opening Interstate H-2 has seen only small changes such as the Ka Uka Boulevard Interchange opening in 1989.  Interstate H-2 was designated the Veterans Memorial Freeway in 2002.  


Part 2; a drive on Interstate H-2 northbound

During 2019 Dan Murphy of Roadwaywiz and Gribblenation drove the entire Interstate H-2 corridor while visiting O'ahu.  Interstate H-2 begins from westbound Interstate H-1 Exit 8A.


Control City signage on Interstate H-2 notes the Ka Uka Boulevard as 1 mile away, Mililani as 4 miles away and Wahiawā as 7 miles away.  

Interstate H-2 northbound Exit 2 accesses Ka Uka Boulevard whereas Exit 5 accesses Mililani/Mauka.


Interstate H-2 northbound Exit 7 accesses Hawaii Route 99 and provides access to Wheeler Army Airfield by way of Leilehua Road. 




Interstate H-2 northbound Exit 8 accesses Hawaii Route 80 in Wahiawā.  As Interstate H-2 northbound terminates it transitions on Hawaii Route 99 on Wilikina Drive.

Part 3; a drive on Interstate H-2 southbound

Interstate H-2 southbound begins at split with Hawaii Route 99/Kamehameha Highway which is signed as Exit 9. 

Interstate H-2 southbound Exit 8 also accesses Hawaii Route 99/Kamehameha Highway at Wahiawā.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

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

Ghost Town Tuesday; Mannfield, FL and the stairway to Hell

Back in 2015 I went searching the Lecanto Sand Hills for the original Citrus County Seat known as Mannfield.  Unlike Centrailia in Hernando County and Fivay in Pasco County I did find something worth seeing. Mannfield is located in the Lecanto Sand Hill section of Withlacoochee State Forest somewhat east of the intersection of Citrus County Route 491 and Mansfield Road. Mannfield was named after Austin Mann and founded in Hernando County in 1884 before Citrus County Split away.  In 1887 Citrus County was split from northern Hernando County while Pasco County was spun off to the south.  Mannfield was selected as the new Citrus County seat due to it being near the county geographic center.  Reportedly Mannfield had as many as 250 people when it was the County Seat.  The town included various businesses one might include at the time, even a sawmill which was common for the area.  In 1891 Citrus County voted to move it's seat to Inverness which set the stage for the decline of M

The National Road - Pennsylvania - Great Crossings Bridge and Somerfield

West of Addison, US 40 crosses the Youghiogheny River at what once was the town of Somerfield.  When crossing the current modern two lane bridge, you many not realize that it is actually the third to cross the Yough at this site.  The first - a stone arch bridge - was known as the Great Crossings Bridge.  Built in 1818, this three arch bridge was part of the original National Road.  The name Great Crossings comes from the men who forded the Youghiogheny here - George Washington and George Braddock. (1)  If you cross the bridge at the right time, this historic bridge and what was once the town of Somerfield will appear out from underneath this massive man-made lake.

The Great Crossings Bridge was located in the town of Somerfield.  Somerfield, originally named Smythfield until 1827, would develop as a result of the National Road.
