California State Route 147

Back in 2014 I drove a small portion of California State Route 147 along the eastern shore of Lake Almanor.


CA 147 is a 12 mile north/south State Highway which begins near Canyon Dam at CA 89 in Plumas County and ends at CA 36 in Westwood of Lassen County.  CA 147 was originally adopted into the State Highway System in 1961 as Legislative Route Number 183.

LRN 183 was adopted onto pre-existing roadways which can be seen by comparing the 1961 State Highway Map to the 1962 Edition.

The roadways now comprising CA 147 are presently part of the Volcanic Legacy Scenic Byway.  The roadways comprising CA 147 are shown on California Division of Highways Maps of Plumas County and Lassen County as major County Highways.

During the 1964 State Highway Renumbering LRN 183 was reassigned CA 147.  This change can be seen by comparing the 1963 State Highway Map to the 1964 Edition.

CA 147 since 1964 has essentially had no significant changes.

CA 147 begins at Post Mile PLU 0.000 at CA 89 near Canyon Dam.   Canyon Dam is an earthen design that was first completed by 1914.  Upon the completion of Canyon Dam the waters of Lake Almanor began be filled by the impounded North Fork Feather River, Benner Creek, Hamilton Creek and Hamilton Branch.  Canyon Dam is part of the Upper North Fork Feather River Project which was conceived by the Great Western Powerhouse Company in the early 1900s.  Canyon Dam was expanded by 1927 before the entirety of the Great Western Powerhouse Company was acquired by Pacific Gas & Electricity by 1930.  Canyon Dam was expanded to it's present 130 foot height by 1962 and the present Lake Almanor has a maximum capacity of approximately 1,308,000 acre feet of water.  Much of Canyon Dam and it's spillway are within walking distance of the south terminus of CA 147.




At Post Mile PLU 4.585 CA 147 passes through the community of East Shore.  At Post Mile PLU 7.369 CA 147 has a junction with Signed County Route A13 in Hamilton Branch.  At approximately PLU 9.990 CA 147 enters Lassen County.   At Post Mile LAS 1.15 CA 147 enters Westwood and meets Signed County Route A21 at 3rd Street.  Westwood dates back to 1913 when it was founded as a company town for the Red River Lumber County.  At approximately Post Mile LAS 1.786 CA 147 has a north terminus at CA 89.

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...
