Hawaii County Route 182

Hawaii County Route 182 is a 3.6-mile highway located on the Big Island. The corridor begins at Hawaii County Route 180 (Mamalahoa Highway) at Holualoa and follows Hualalai Road west to Alii Drive (Hawaii County Route 187) in Kailua-Kona. Hawaii County Route 182 includes a brief multiplex of Hawaii Route 11 and was likely added to the Federal Aid-System on the Big Island during the late 1970s.

Part 1; the history of Hawaii County Route 182

Hualalai Road has been present serving Kailua-Kona and Holualoa for decades prior to the expansion of the state highway system to the Big Island in 1955. The corridor is shown to be a major local roadway on the 1959 Gousha Highway map of Hawaii.

According to Oscar Voss's hawaiihighways.com Hualalai Road wasn't added to the Federal Aid-System on the Big Island during 1960s but rather at a later time. The corridor was likely added during 1976 or sometime after. This is likely due to the Hawaii Route 11 being shifted onto an extension of Queen Kaahumanu Highway south of Kailua-Kona. The extension of Queen Kaahumanu Highway partially bisected Hualalai Road.

Modern Hualalai Road appears on the 1998 United States Geological Survey map as a major highway (courtesy historicaerials.com). The original definition of Hawaii County Route 182 included the entire 3.6 miles of Hualalai Road in addition to 0.3 miles of Alii Drive in Kailua-Kona. Alii Drive was later reassigned during the early 2000s as part of the then newly designated Hawaii County Routes 187.

Part 2; a drive on Hawaii County Route 182

Westbound Hawaii County Route 182 beings at Hawaii County Route 180 (Mamalahoa Highway) in Holualoa. Hawaii County Route 182 is not signed with reassurance shields but rather Mile Markers which denote the route number.

Hawaii County Route 182/Hualalai Road drops from the mountains near Holualoa and intersects Hawaii Route 11/Queen Kaahumanu Highway.

Hawaii County Route 182 briefly multiplexes Hawaii Route 11 to the bisected western segment of Hualalai Road. Hawaii County Route 182 is mistakenly signed as Hawaii County Route 180 on-route along Hawaii Route 11.

Hawaii County Route 182 quickly descends into Kailua-Kona and intersects the original alignment of Hawaii Route 11 at Kuakini Highway.

Hawaii County Route 182 terminates at Hawaii County Route 187/Alii Drive in Kailua-Kona.

Trimmer Springs Road (Fresno County)

Trimmer Springs Road is an approximately forty-mile rural highway located in Fresno County. The corridor begins near in California State Route 180 in Centerville and extends to Blackrock Road at the Kings River in the Sierra Nevada range near the Pacific Gas & Electric Company town of Balch Camp. The roadway is named after the former Trimmer Springs Resort and was originally constructed to facilitate access to the Sanger Log Flume. Trimmer Springs Road was heavily modified and elongated after construction of Pine Flat Dam broke ground in 1947. Part 1; the history of Trimmer Springs Road Much of the original alignment of Trimmer Springs Road was constructed to facilitate access to the Sanger Log Flume. The Kings River Lumber Company had been established in 1888 in the form of a 30,000-acre purchase of forest lands in Converse Basin. This purchase lied immediately west of Grant Grove and came to be known as "Millwood." The co...

When was Ventura Avenue east of downtown Fresno renamed to Kings Canyon Road? (California State Route 180)

California State Route 180 was one of the original Sign State Routes designated in August 1934. The highway east of Fresno originally utilized what was Ventura Avenue and Dunlap Road to reach what was then General Grant National Park. By late year 1939 the highway was extended through the Kings River Canyon to Cedar Grove. In 1940 General Grant National Park would be expanded and rebranded as Kings Canyon National Park. The Kings Canyon Road designation first appeared in publications circa 1941 when the California State Route 180 bypass of Dunlap was completed. Kings Canyon Road ultimately would replace the designation of Dunlap Road from Dunlap to Centerville and Ventura Avenue west to 1st Street in Fresno. The Kings Canyon Road would remain largely intact until March 2023 when the Fresno Council designated Cesar Chavez Boulevard. Cesar Chavez Boulevard was designated over a ten-mile corridor over what was Kings Canyon Road, remaini...

Interstate 99 at 30

When it comes to the entirety of the Interstate Highway System, Interstate 99, when fully completed, is nothing more than 161 miles of a roughly 48,000-mile system (0.3% of total length). Yet, to more than just a handful of people, the number '99' rubs them the wrong way. Interstate 99 follows the path of two US Highway Routes - US 220 from the Pennsylvania Turnpike in Bedford north to Interstate 80 and then to US 15/Interstate 180 in Williamsport. It then follows US 15 from Williamsport north to Interstate 86 in Corning, New York. Interstate 99 runs with US 220 through much of Central Pennsylvania. (Doug Kerr) US 220 from Cumberland, Maryland to Interstate 80 and US 15 north of Williamsport were designated part of the Appalachian Highway System in 1965. Construction to upgrade both corridors progressed steadily but slowly. In 1991, the two corridors were included as a National High Priority Corridor. The route from Cumberland to Corning consisted of High P...
