Hawaii Route 250


Hawaii Route 250 is a 19.3-mile highway located on the Big Island.  The corridor begins at Hawaii Route 19 in Waimea and terminates at Hawaii Route 270 in Hawi.  The corridor of Hawaii Route 250 crosses Kohala Mountain via the so-called Kohala Mountain Road and descends into Hawi via Hawi Road.  Kohala Mountain Road was the original overland highway to Hawi and was originally assigned as Hawaii Route 25 when the Hawaii Route System was expanded to the Big Island in 1955.

Part 1; the history of Hawaii Route 250

The majority of Hawaii Route 250 traverses Kohala Mountain Road between Waimea and Hawi.  Kohala Mountain is an extinct shield volcano which makes up the northwest portion of the Big Island.  The mountain is thought to have breached the Pacific Ocean approximately 500,000 years ago and was last active approximately 120,000 years ago.  Much of the northeast portion of the mountain collapsed via a massive landslide approximately 250,000-300,000 years ago.  Currently Kohala Mountain rises to 5,480 feet above sea level.  

The 1912 United States Geological Survey Map of Kohala displays Hawi and Waimea connected by the "Waimea-Kona Road."  This road essentially is an overlay for the modern corridor of Kohala Mountain Road. 



Kohala Mountain Road can be seen prominently displayed as the only road to Hawi on the 1930 Hilo Chamber of Commerce map of the Big Island.  


In 1955 the Hawaii Route System was expanded to the Big Island.  The existing highway between Waimea-Hawi via Kawaihae Road, Kohala Mountain Road and Hawi Road was assigned as Hawaii Route 25.  Hawaii Route 25 appears on the 1959 Gousha Highway map of Hawaii.  


In 1975 Hawaii Route 19 was moved to the then new Queen Kaahumanu Highway.  The new alignment also consumed parts of Hawaii Routes 26 and 25 along Kawaihae Road.  Hawaii Route 25 was renumbered to Hawaii Route 250 and truncated to begin at Kohala Mountain Road in Waimea.  For this reason, Hawaii Route 250 begins at Mile Marker 2.6 rather than 0. 

Hawaii Route 250 can be seen on the 1975 United States Geological Survey map of the Big Island.




Part 2; a drive on Hawaii Route 250

Northbound Hawaii Route 250 begins on the western outskirts of Waimea as Kawaihae Road meets Kohala Mountain Road.  Northbound Hawaii Route 250 begins at Mile Marker 2.6. 




Northbound Hawaii Route 250 quickly ascends Kohala Mountain above Waimea.  A sweeping vista of Kailua-Kona can be seen facing south and the looming Mauna Kea can be seen to the west.  




















Northbound Hawaii Route 250 has a signed vista which faces over the northwest corner of the Big Island.















Hawaii Route 250 crests at an elevation of 3,564 feet above sea level near Kahua Ranch. 




Hawaii Route 250 passes by Kahau Ranch Road.  










Hawaii Route 250 crosses to the northern side of Kohala Mountain and drops below 3,000 feet above sea level.














Hawaii Route 250 approaches the end of Kohala Road at the intersection of Hawi Road and Kynnersley Road.  The highway turns left on Hawi Road towards Hawi. 











Northbound Hawaii Route 250 descends Hawi Road and terminates at Hawaii Route 270 in Hawi.  The terminus of Hawaii Route 250 is located at Mile Marker 21.8.  The Hawi townsite is located near the birthplace of Kamehameha I along the windward side of Kohala Mountain.  The modern community was founded as a company town of the Kohala Sugar Company.  Kohala Sugar began operations on the Big Island in 1863 and was active in Hawi until 1973.

Abandoned Fowler Avenue in Clovis, California

Originally Fowler Avenue in the city of Clovis had a brief discontinuation approaching Herndon Avenue.  Fowler Avenue traffic heading northbound was required to detour briefly onto westbound Herndon Avenue.  During 2001 this discontinuation was removed when Fowler Avenue was reconfigured to access the Sierra Freeway (California State Route 168) via an interchange.  This led to a segment of the original alignment of Fowler Avenue just south of Herndon Avenue to be abandoned.  Despite a shopping center opening over part of the original Fowler Avenue alignment in 2016 much of the abandoned roadway remains.   The history of the abandoned original alignment of Fowler Avenue in Clovis The original alignment of California State Route 168 departed downtown Clovis eastbound along Tollhouse Road.  This original alignment did not interact with Fowler Avenue at the Herndon Avenue intersection.  Fowler Avenue north of Tollhouse Road ran north to Herndon Avenue...

What's In a Name?: When the Roads Really Do Tell a Story

  Our tagline on the Gribblenation blog is "because every road tells a story". Some roads tell different stories than others. Along our travels, we may see historic markers that tell us a little story about the roads we travel or the places we pass by. Some historic markers are more general, as to telling us who lived where or what old trail traversed between two towns. During my travels across New York State and other states or provinces, I pass by many historic markers, some with interesting or amusing references to roads. I wanted to highlight a few of the markers I've seen along my travels around the Empire State and help tell their stories. Those stories may be as specific as explaining the tales of a tree that was used to help measure a distance of eight miles from Bath to Avoca in Steuben County, as referenced on the Eight Mile Tree historical marker above. They may also help point the way along historical roads first used centuries ago, or may help tell a local l...

Zayante Road and Upper Zayante Road

The combined 11-mile corridor Zayante Road and Upper Zayante Road is located in the Santa Cruz Mountains near Felton in Santa Cruz County.  The corridor begins as Zayante Road at Graham Hill Road near the Felton Covered Bridge.  Zayante Road passes through the namesake community of Zayante where it becomes Upper Zayante Road upon intersecting Old Mountain Road.  Upper Zayante Road makes a final ascent to California State Route 35 at Summit Road via a grade which peaks at an incline of 11%. Zayante Road was built as a frontage of the South Pacific Coast Railroad in 1879.  As originally configured Zayante Road terminated a short distance north of Zayante Station.  Zayante Station itself was commissioned in 1891 to service the resort at Gibbs Ranch.  Upper Zayante Road would later be constructed in the first decade of the Twentieth Century as a continuation of Zayante Road to Summit Road.   Part 1; the history of Zayante Road and Upper Zayante Road B...
