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.

Oldtown Toll Bridge - Maryland and West Virginia

  The Oldtown Toll Bridge linking Oldtown, Maryland over the Potomac River with neighboring Green Spring, West Virginia is only one of a few truly privately owned toll bridges located in the United States. It's a simple bridge by design, as the 318 foot long Oldtown Toll Bridge is a low water bridge. Low water bridges are designed to allow water to safely and efficiently flow over the bridge deck. Additionally, a dozen concrete pedestals have been secured in the Potomac River in order to support the bridge and wooden deck. The bridge was constructed in 1937 when a gentleman by the name of Mr. Carpenter obtained the proper permits to build the Bridge through an Act of Congress. This was a blessing for residents, especially on the West Virginia side of the Potomac River, as it saved motorists commuting to Cumberland an hour in travel time. Using Mr. Carpenter's blueprints, the Army Corp of Engineers and a number of local laborers constructed the bridge and it remained under the
