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.

Former US Route 50 and the Pioneer Route Lincoln Highway on Johnson's Pass Road

Johnson's Pass Road is one of the oldest highway corridors in California.  Johnson's Pass was part of the Lake Tahoe Wagon Road as it was completed during 1856 over the Sierra Nevada.  The pass would later be incorporated into the Pioneer Branch of the Lincoln Highway in 1913 and US Route 50 in 1926.  Johnson's Pass Road would be bypassed by a new alignment of US Route 50 over Echo Summit in 1938.  A replacement of the Meyers Grade east of Johnson's Pass would be opened to traffic in 1947.   Johnson's Pass Road remains accessible to traffic and is still signed by the Lincoln Highway Association.  Pictured as the blog cover is the view from the top of Johnson's Pass Road overlooking modern US Route 50 and Lake Tahoe.   Part 1; the history of Johnson's Pass Much of the history of what become the Lake Tahoe Wagon Road is discussed in the  September 1950 California Highways & Public Works  during its Centennial Edition.  The or...

Former US Route 50 and the South Lincoln Highway from Folsom east to Placerville

The corridor of Folsom of Sacramento County east to Placerville of El Dorado County has been a long established corridor of overland travel dating back to the California Gold Rush.  The Folsom-Placerville corridor was once part of the path of the Lake Tahoe Wagon Road which became the first California State Highway and later the South Lincoln Highway.  In time the South Lincoln Highway's surface alignment was inherited by US Route 50.  The Folsom-Placerville corridor also includes the communities of; Clarksville, Shingle Springs and El Dorado. Part 1; the history of the Lake Tahoe Wagon Road, South Lincoln Highway and US Route 50 through Folsom-Placerville Folsom is located on the American River/Lake Natoma of eastern Sacramento County.  That lands now occupied by the City of Folsom were part of Rancho Rio de los Americanos prior to the finding of gold at Sutter's Mill during 1848.  During the California Gold Rush the lands of Rancho Rio de los Americanos were p...

Angus L. Macdonald Bridge

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...
