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.

Breezewood - The Rise and Decline of a Highway Rest Stop

It's the Pennsylvania Turnpike Interchange most people hate - and with a passion.  The Breezewood Interchange - a junction of two Interstates (70 & 76) that became complicated due to archaic rules, rural politics and power, and an unwillingness to change.  At its romanticized best, this small unincorporated community of under 100 residents is a reminder of travel days of the 1950s-1970s; at its worst, it is a gradually dying relic of old motels and services that drivers are forced to slow down and drive through on their way to bigger and more modern destinations.

The Breezewood Interchange is an exception to the rule in the Interstate Highway System.  Depending on your direction, Interstate 70 joins or leaves the Pennsylvania Turnpike (Interstate 76) here.  However, unlike nearly every Interstate junction in the United States - Interstate 70 must traverse on a roughly 1/4 mile stretch of US 30.  A four lane highway complete with traffic lights, center turn lanes to cross traffi…

Old US Route 99 in Goshen, Traver, and the Warlow Rest Area

This summer I had a look into the alignment history of US Route 99 through the Tulare County communities of Traver and Goshen.  The photo below is take from Camp Drive northbound in Goshen on what was US Route 99 until the early 1930s.



Part 1; the history of US Route 99 in Goshen and Traver

Goshen and Traver were both founded in 1872 as sidings of the Southern Pacific Railroad.  The Southern Pacific Railroad laid the groundwork for development of southern San Joaquin Valley.  Previous to the Southern Pacific Railroad travel via wagon or foot in Central California tended to avoid San Joaquin Valley in favor of the Stockton-Los Angeles Road.  The Stockton Los Angeles Road lied to the east of San Joaquin Valley in the Sierra Nevada Foothills and was less subject flooding.  Before the Southern Pacific Railroad most of San Joaquin Valley was a sparsely inhabited wetland which made travel by road difficult.  Goshen and Traver can along the Southern Pacific Railroad on the 1873 Ore…

California State Route 283; former US Route 101 over the Rio Dell Bridge

This week we examine one of California's shortest State Highways; California State Route 283.  California State Route 283 includes the 1941 Rio Dell Bridge and is a former segment of US Route 101.  The photo below is the Rio Dell Bridge after the 1964 Christmas Floods which wiped out the northern approach span. 


California State Route 283 ("CA 283") is a 0.36 Mile State Highway between modern US Route 101/Redwood Highway and the community of Rio Dell in Humboldt County.  The key feature of CA 283 is the 1941 Rio Dell Bridge which was the second alignment of US Route 101.  The Rio Dell Bridge connected Scotia north over the Eel River via Wildwood Avenue to Rio Dell.  The Rio Dell Bridge is a steel truss design which 1,643.1 feet in length.  The Rio Dell Bridge is also known as; North Scotia Bridge, Eel River Bridge, Scotia-Rio Dell Bridge, Albert Stanwood Murphy Memorial Bridge, and the Eagle Prairie Bridge.  CA 283 is unsigned presently ranks as the second shortest State…
