Maui County Route 390


Maui County Route 390 is a 12.1-mile highway which exists on the Island of Maui.  Maui County Route 390 connects the communities of Paia, Makawao and Olinda via Baldwin Avenue and Olinda Road.  Maui County Route 390 was originally assigned as Hawaii Route 39 when the 1955 Hawaii Route System was established.  


Part 1; the history of Hawaii Route 39 and Maui County Route 390

The Island of Maui seemingly was not part of the original World War II era Hawaii Route System.  Circa 1955 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 the Island of Maui it was assigned numbers in the range of 30-40.

Hawaii Route 39 was aligned from Paia to Makawao via 7 miles of Baldwin Avenue and 5.1 miles of Olinda Road to Olinda.  Hawaii Route 39 can be seen on the 1959 Gousha Highway Map of Hawaii.  

The southern terminus of Hawaii Route 39 in Olinda is shown on the 1957 United States Geological Survey Map of Kilohana to end at the Kailua Gulch Jeep Trail near Olinda Prison Camp.  The Kailua Gulch Trail is shown to connect Hawaii Route 39 to Hawaii Route 378/Haleakala Highway near the boundary to Haleakala annex of Hawaii Volcanos National Park.  


Hawaii Route 39 seems primarily to have existed to service Olinda Prison Camp.  Olinda Prison Camp was in operation from 1926 until it shuttered during 1973.  Reportedly Olinda Prison Camp had a declining inmate population and difficulties keeping staffing in a remote location on Haleakala's northern flank.  According to hawaiihighways.com, the Hawaii Department of Transportation once considered upgrading the Kailau Gulch Jeep Trail as part of Hawaii Route 39 during the 1960s but had abandoned the idea by no later than 1967.  According to hawaiihighways.com, Maui County Route 390 appears on a 1976 Maui County planning map and the 1981 Maui County Route log.  


Part 2; scenes around Maui County Route 390

Maui County Route 390 begins in Paia via Baldwin Avenue south from Hawaii Route 36/Hana Highway.  No Maui County Route 390 signage appears on Hawaii Route 36 in Paia approaching Baldwin Avenue.  Paia was founded in 1880 as the site of a Hawaiian Commercial & Sugar mill and siding of the Kahului Railroad.



Maui County Route 390 signage can be found along Maui County Route 365 in Makawao.  Maui County Route 365 serves as the point where Maui County Route 390 transitions from Baldwin Avenue to Olinda Road.  


Maui County Route 390 follows Olinda Road to a southern terminus near the site of the former Olinda Prison Camp.  An oddly misshapen Hawaii Route 39 shield was once present (and might still be) as recently as 2011 (according to Google Street View).


From Hawaii Route 378/Haleakala the Kailau Gulch Jeep Trail can still be identified (behind the pylons) near the Haleakala National Park boundary.  It isn't clear if the Kailau Gulch Jeep Trail can still be used to reach Maui County Route 390.

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 s...

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...

The mystery of Hawaii Route 144 and temporary Hawaii Route 11

The 1959 Gousha Road map of Hawaii features two largely unknown references in the form of Hawaii Route 144 and Temporary Hawaii Route 11.  Both corridors are shown running from the boundary of Hawaii Volcanoes National Park east to Glenwood via Volcano Village.  At the time Hawaii Route 11 was using the so-called "Volcano Road" which was constructed as a modernization of Mamalahoa Highway during 1927-1928.  This blog will examine the two map references and will attempt to determine what they might indicate.  The mystery of Hawaii Route 144 and Temporary Hawaii Route 11 Hawaii Route 11 is part of Mamalahoa Highway (the Hawaii Belt Road) and is the longest Hawaiian State Route at 121.97 miles.  The highway begins at the mutual junction of Hawaii Route 19 and Hawaii Route 190 in Kailua-Kona.  From Kailua-Kona the routing of Hawaii Route 11 crosses the volcanic landscapes of southern side of the Big Island.  Hawaii Route 11 terminates at Hawaii Route 19/Ka...
