California State Route 126; from CA 23 east to Santa Clarita

This past month I drove a segment of California State Route 126 from CA 23 in Fillmore east to Santa Clarita.


CA 126 in present form is a 47 mile east/west State Highway which has a western terminus in Ventura at US 101 and an eastern terminus on Newhall Ranch Road in Santa Clarita.  CA 126 was created on Legislative Route Number 79 in 1934.  LRN 79 was created in 1931 which followed the Santa Clara River between LRN 2/US 101 in Ventura east to LRN 4/US 99 in Castaic.

The original route of CA 126 as defined in 1934 used the following alignment from Ventura eastward:

-  From US 101/LRN 2 in Ventura east on modern day Telegraph Road to Steckle Drive in Santa Paula.
-  Steckle Drive to Main Street in Santa Paula.
-  Main Street to Telegraph Road.
-  Telegraph Road to Ventura Street in Fillmore.
-  Ventura Street to Telegraph Road.
-  Telegraph Road to Edwards Canyon Road.
-  Edwards Canyon Road to Pacific Avenue.
-  Pacific Avenue to Main Street in Piru.
-  Main Street to Via Fustero in Piru.
-  Via Fustero to Center Street in Piru.
-  Center Street to Telegraph Road.
-  Telegraph Road to the Los Angeles County line.
-  From the Los Angeles County line Henry Mayo Drive.
-  Henry Mayo Drive to US 99 on The Old Road near Castaic. 

The above alignment above was gradually straightened and is still part of CA 126 on the segments not on the Santa Paula Freeway.  The above alignment can be seen on the 1935 California Division of Highways Maps of Ventura County and Los Angeles County.

CA 126 appears to have been temporarily extended into downtown Ventura in 1963 via Main Street when US 101 was shifted to the Ventura Freeway.

In 1964 the route of CA 126 was extended from US 99 (modern I-5) east to what had been US 6 (modern CA 14) near Newhall Pass on a previously unsigned portion of LRN 79.  1964 is also notable since the first segment of the Santa Paula Freeway alignment of CA 126 between US 101 and CA 118 is shown complete.  In full scope Santa Paula Freeway was intended to be built from the Ventura Freeway east to the Golden State Freeway.

For reference LRN 79 had been extended in 1939 over a former segment of LRN 4 between Castaic and Newhall.  This partial section of CA 126 was relinquished in 2001 but carries historical significance as it was part of early US 99 leading to the Old Ridge Route.  More on this segment of CA 126 east from I-5 to CA 14 near Newhall Pass can be found in Chapter 11 of the Legend of the Ridge Route blog.

The 1967 State Highway Map shows the current route of the Santa Paula Freeway between Ventura and Santa Paula as complete.

Presently there is plans to build a new alignment of CA 126 from I-5 east through Santa Clarita to CA 14 known as the Santa Clarita Veterans Parkway.  The Santa Clarita Veterans Parkway was originally conceived as a freeway proposal by Caltrans in 1990.  The freeway was ultimately rejected and a new plan known as the Cross-Town Connector was drafted in 2005 which became known as the Santa Clarita Veterans Parkway by 2016.

My approach to CA 126 east was from CA 23 north in Fillmore of Ventura County.  CA 126 east of CA 23 is signed on Ventura Street in Fillmore and is signed as 19 miles Santa Clarita.


CA 126 east of Fillmore becomes Telegraph Road and crosses a set of rails.






CA 126 east traverses the north bank of the Santa Clara River towards Santa Clarita.  East of Sycamore Road CA 126 on Telegraph Road crosses the rails a second time.







As CA 126 east enters the outskirts of Piru the highway passes by it's former alignment on Main Street.  Main Street is signed as access to the Lake Piru Recreation Area.




Modern CA 126 east bypasses Piru and picks up the other end of the original highway at Center Street.



CA 126 east of Piru passes by Rancho Camulos which was constructed in the 1850s off of a previous Mexican Land Grant.




CA 126 east continues on Telegraph Road to the Los Angeles County line.








CA 126 east follows Henry Mayo Drive to I-5 on the outskirts of Santa Clairta.















CA 126 east terminates just past I-5 in Santa Clarita on Newhall Ranch Road.

Hetch Hetchy Valley; Hetch Hetchy Railroad, abandoned Lake Eleanor Road, and the Wapama Fall Bridge

This June I took a trip out to Yosemite National Park upon receiving my COVID-19 Day Use Reservation.  My destination in Yosemite National Park was out in Hetch Hetchy Valley.  I sought to hike to the Wapama Fall Bridge which took me through some of the path of the former Hetch Hetchy Valley Railroad and abandoned Lake Eleanor Road.



Part 1; Hetch Hetchy Valley, the Hetch Hetchy Railroad, and reservoir roads

Hetch Hetchy is glacially carved valley similar to Yosemite Valley which is located on the Tuolumne River of Tuolumne County.  Hetch Hetchy Valley presently is impounded by the O'Shaughnessy Dam which was completed during 1923 as part of a project to deliver water and hydroelectric power to the City of San Francisco.  Before being impounded Hetch Hetchy Valley had an average depth of approximately 1,800 feet with a maximum depth of approximately 3,000 feet.  Hetch Hetchy Valley is approximately three miles long and as much as a half mile wide.  Hetch Hetchy Valley is located dow…

Mineral King Road, the White Chief Mine, and the unbuilt California State Route 276

Back in July of 2016 I took Mineral King Road east from California State Route 198 to Mineral King Valley within the Sierra Nevada Mountains of Sequoia National Park.  This June I revisited Mineral King Valley and made my way up to the White Chief Mine.


Mineral King Road is a 24.8 mile rural highway maintained by the National Park Service and as Tulare County Mountain Road 375.  Mineral King Road originates at California State Route 198 in Three Rivers near the confluence of the Middle Fork Kaweah River and the East Fork Kaweah River.  Mineral King Road climbs from a starting elevation of 1,400 feet above sea level to 7,830 feet above sea level at the White Chief Mine Trailhead in Mineral King Valley.  Notably Mineral King Road is stated to have 697 curves.


Mineral King Road has an average grade of 5.1% but has several stretches between 15-20% in places.  Pjammycycling has a detailed breakdown on the grade levels over the entirety of Mineral King Road.

California's Rogue Sign State Route Shields

While recently revisiting Yosemite National Park I took a couple minutes to capture some of the California Sign State Route shields posted by the National Park Service ("NPS").  None of the NPS shields were actually posted on roadways maintained by Caltrans but were clearly intended to create route continuity with the Sign State Highways.  This phenomenon is not exclusive to Yosemite National Park and can be found on numerous roads not maintained by Caltrans throughout California.



Part 1; Route continuity over who maintains the route

In the very early era of State Highways in California the Division of Highways didn't actually field sign the Auto Trails or even US Routes.  The responsibility of Highway signage fell to the California State Automobile Association ("CSAA") and Automobile Club of Southern California ("ACSC").  The Auto Clubs simply signed Highways on roadways that best served navigational purposes.  These navigational purposes often didn&#…
