California State Route 14 on the Antelope Valley Freeway

This past year I drove the entirety of California State Route 14 on the Antelope Valley Freeway south from the Kern County Line to I-5 at Newhall Pass.


The present CA 14 is a 117 mile north/south State Highway which begins at US 395 and ends at I-5 near Newhall Pass.  Present day CA 14 is tied to numerous historically important Californian highways dating back to the times of wagon routes up to the era of the US Route System.


A great deal of early history of what became modern day CA 14 was discussed in the "Legend of the Ridge Route" regarding the realignment of State Highways in Newhall Pass:

"Chapter 3; practicality leads to Ridge Route Alternate through Piru Gorge

US 99/LRN 4 from the south end of the Ridge Route at Castaic Junction through Newhall Pass originally had been routed on; (what is now) Magic Mountain Parkway, Railroad Avenue, Newhall Avenue, and San Fernando Road.  In 1931 a new routing of US 99/LRN 4 bypassing Newhall Pass, Saugus and Newhall to Castaic Junction was constructed through Weldon Canyon on what is now known as The Old Road.  The former alignment of US 99/LRN 4 from Castaic Junction through Saugus and Newhall was partially reused as part of CA 7/LRN 23 and later by US 6 when it was routed to Long Beach in 1937.  US 6/LRN 23 entered Saugus via Soledad Canyon Road on the south bank of the Santa Clara River to Bouquet Canyon Road.  From Bouquet Canyon Road US 6 turned south towards Railroad Avenue and downtown Newhall.  US 6/LRN 79 followed Railroad Avenue and Newhall Avenue to San Fernando Road to reach Newhall Pass.  Former LRN 4 in from Castaic Junction to US 6/LRN 23 in Saugus was assigned to LRN 79 in 1939 according to CAhighways.org.  In 1940 US 6/LRN 23 bypassed Saugus and Newhall on a more more direct route to Newhall Pass on the new Sierra Highway.   Although the legislative definition of LRN 79 wasn't extended to Sierra Highway and US 6/LRN 23 until 1957 it was maintained as a State Highway through Newhall nonetheless.  LRN 79 was reassigned as part of CA 126 in 1964 and remained in the State Highway system until 2001."

Understanding highways in a historical context through Newhall Pass is incredibly complex and lengthy.  Newhall Pass has been a major corridor of transportation since Spanish Las Californias.  Given the large historic scope, I would highly suggest reading the full Legend of the Ridge Route blog for proper historical context regarding Newhall Pass.

Legend of the Ridge Route; a history of crossing the mountains between the Los Angeles Basin and San Joaquin Valley

The current designation of CA 14 was created during the 1964 State Highway Renumbering.  CA 14 from US 395 south to Newhall Pass was carved out of what was US 6 on LRN 23.  The unbuilt portion of CA 14 south to CA 1 in Pacific Palisades was defined as LRN 290 in 1959.  The change from US 6/LRN 23/LRN 290 to CA 14 can be seen by comparing the 1963 State Highway Map to the 1964 Edition.

1963 State Highway Map 


1964 State Highway Map 


The 1964 State Highway Map above shows part of CA 14 shifted to the Antelope Valley Freeway east of Saugus.  By 1966 the Antelope Valley Freeway was extended east to the planned junction with CA 249 and CA 122.  The planned route of the Antelope Valley Freeway through Palmdale also appears on the 1966 State Highway Map.



The 1967 State Highway Map shows the Antelope Valley Freeway completed between Saugus and Palmdale.  A small stub of the Antelope Valley Freeway is shown completed east of I-5 in New Hall Pass to Newhall Avenue/CA 126


The alignment of CA 14 north of Lancaster to Rosamond is shown shifted to a new expressway alignment on the 1969 State Highway Map.


The 1970 State Highway Map shows the Antelope Valley Freeway completed between I-5 in Newhall Pass to Palmdale.


Sometime between 1970 and 1975 the Antelope Valley Freeway was completed north of Palmdale to Lancaster.


It should be noted that part of Sierra Highway between Placerita Canyon Road and Golden Canyon Road is still under State Maintenance as CA 14U.  Presently Caltrans is attempting to repair the CA 14U section of Sierra Highway to turn over to the City of Santa Clarita.

Also of note, I recently drove a portion of CA 14 on the Antelope Valley Freeway north from Palmdale to Avenue D north of Lancaster.  Said portion of the Antelope Valley Freeway is co-signed as CA 14/CA 138.

California State Route 138

My approach to CA 14 south towards the Antelope Valley Freeway was via CA 58 east in Mojave of Kern County.  CA 58 east intersects CA 14 south at Exit 167.  As the name of the community implies Mojave is indeed in the Mojave Desert.






CA 14 south of CA 58 is signed on the Aerospace Highway in Mojave.  At Post Mile 16.07 CA 14 south intersects the CA 58 Business Route in downtown Mojave which is the old alignment of US Route 466.  Interestingly CA 14 south in Mojave has at least one "Grand Army of the Republic" shield which really calls back to the fact that the highway was once US 6.









CA 14 south multiplexes CA 58 BL east through downtown Mojave.  CA 58 BL splits east away from CA 14 at Post Mile L16.093 in downtown Mojave at Mojave-Barstow Highway.






CA 14 south of CA 58 BL expands to an expressway and crosses over a large rail overpass.  CA 14 south from Mojave is signed as 97 miles from Los Angeles.





CA 14 south expands to a freeway at Exit 64 for Silver Queen Road.




CA 14 south at Exit 61 accesses Backus Road.






CA 14 south enters Rosamond and accesses Dawn Road at Exit 58.



At Exit 55 CA 14 south has a junction with Rosamond Boulevard which is signed as access to Rosamond, Willow Springs International Raceway and Edwards Air Force Base.

At Exit 42 CA 14 south/CA 138 accesses Avenue K.




At Exit 41 CA 14 south/CA 138 east accesses Avenue L and enters Palmdale.





At Exit 39 CA 14 south/CA 138 east accesses Avenue N.



At Exit 37 CA 14 south/CA 138 accesses 10th Street West.





At Exit 35 CA 138 east splits away from CA 14 south via Palmdale Boulevard.  Signed County Route N2 can be accessed via Exit 35 on Elizabeth Lake Road.



Access to Lake Palmdale via Avenue S is signed from Exit 33.  CA 14 south of Palmdale crosses the California Aqueduct and is signed as a Safety Corridor.






At Exit 30 CA 14 south has a junction with CR N3 on National Forest Highway and Pearblossom Highway.  CR N3 essentially exists on part of the corridor of the planned CA 249 which would have continued south to CA 2 on the Angeles Crest Highway.  Pearblossom Highway exists partially on the corridor of the planned CA 122.   There is also access to former US 6 on Sierra Highway from Exit 30.  CA 14 south also begins to follow the Santa Clara River at Exit 30.




Santa Clarita is signed as 27 miles away on CA 14 south on the Antelope Valley Freeway past CR N3.


Exit 27 on CA 14 south provides access to Soledad Canyon Road and Sierra Highway.




Exit 26 on CA 14 south accesses Santiago Road.  Exit 24 accesses Sierra Highway, Crown Valley Road and Red Rover Mine 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&#…
