California State Route 284

California State Route 284 is an eight-mile State Highway located entirely in Plumas County. California State Route 284 begins at California State Route 70 in Chilcoot and terminates at Frenchman Reservoir. California State Route 284 is one of many pre-existing roads which were annexed into the State Highway System by way of 1970 Legislative Chapter 1473. Above as the blog cover photo is a southward view on California State Route 284 (taken by Josh Schmid) as it descends from Frenchman Reservoir on Frenchman Lake Road.

Part 1; the history of California State Route 284 and unconstructed California State Route 285

California State Route 284 (CA 284) was adopted as part of 1970 Legislative Chapter 1473. CA 284 was designated as a highway connecting from Route 70 in Chilhoot to Frenchman Reservoir. Legislative Chapter 1473 defined numerous State Highways during 1970, some of the others include CA 283, CA 281, CA 271, and CA 270.

Notably the Chapter 1473 State Highways appear to have been contingent that an existing roadway be built to State Highway Standards. To that end Frenchman Lake was completed as a California Department of Water Resources irrigation project by 1961 along Little Last Chance Creek. The existing Frenchman Lake Road appears to have been improved during the Frenchman Lake project and was adopted as the alignment of CA 284. Notably modern Frenchman Lake Road appears on the 1935 Division of Highways Map of Plumas County north of Chilhoot.

On the 1975 Caltrans State Highway Map the full 8-mile route of CA 284 appears as a fully functional State Highway.

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...
