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 52 approaching Avenue A CA 14 south enters Los Angeles County.



At Exit 49 CA 14 south meets CA 138 at Avenue D.




CA 14 south begins a multiplex with CA 138 east.  Signage of the Antelope Valley Freeway begins on CA 14 south of Exit 49.



CA 14 south/CA 138 east meet Avenue F at Exit 47.



At Exit 46 CA 14 south/CA 138 east enters Lancaster and has access to Avenue G.  Traffic is directed to follow Avenue G to Fox Airport.





At Exit 45 CA 14 south/CA 138 accesses Avenue H.


CA 14 south/CA 138 east access downtown Lancaster via Avenue I at Exit 44.  Avenue I westward is the former alignment of CA 138 and the most direct access to the California Poppy Reserve.





CA 14 south/CA 138 east meet Signed County Route N5 at Exit 43 for Avenue J.



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.





CA 14 south Exit 19 accesses Escondido Canyon Road.






CA 14 south begins to descend downhill approaching Exit 15 Aqua Dulce Canyon Road.











CA 14 south descends below 2,000 feet above sea level and at accesses Soledad Canyon Road.

Signed County Route J37; the last Signed Tulare County Route and the Lone Pine to Porterville High Sierra Road

Recently I drove the entirety of Signed County Route J37 located in rural Tulare County.  Signed County Route J37 is notable in that it is the last Signed County Route which actually has field signage left in Tulare County and was intended to be part of a Trans-Sierra Highway known as the Lone Pine to Porterville High Sierra Road.


While researching California State Route 190 and more specifically the gap in the highway over the Sierra Nevada Range it became quickly apparent that there was far more to J37/Balch Park Road than initially thought.  The previous blog on California State Route 190 can be found here:

On the above blog I attached an article from 1926 written by the Los Angeles Times detailing the route of the Lone Pine to Porterville High Sierra Road which was slated to begin construction in 1927.  The route of the Lone Pine to Porterville High Sierra Road would have followed Carroll Creek southward out…

Paper Highways of the Mojave Desert and San Gabriel Mountains; CA 48 (ii), CA 122, CA 196, and CA 249

In this edition Paper Highways the planned California State Highways of the Mojave Desert and San Gabriel Mountains are explored.  This issue will cover the planned routes of; the second CA 48, CA 122, CA 196, and CA 249.



Part 1; the wholesale Legislative Route adoptions of 1959

CA 48, CA 122, CA 196, and CA 249 prior to the 1964 State Highway Renumbering all were adopted as planned Legislative Routes ("LRN") in 1959.  Part of the planned LRN 267 west of Lancaster was already part of the existing CA 138 on LRN 59.  CA 48 east of Lancaster was planned as LRN 267 which was to have an eastern terminus at LRN 266.  LRN 266 was planned to originate from CA 2/LRN 61 near La Canada Flintridge and cross north/northeast over the San Gabriel Mountains into the Mojave Desert near Palmdale.  LRN 266 was planned to continue northeast from Palmdale to former US 466/LRN 48 near Hawes.  LRN 266 became CA 249 and CA 122 during the 1964 State Highway Renumbering.  LRN 269 was planned to be rou…

Old California State Route 65 on; Famoso-Porterville Highway, Sign County Routes J35/J22/J29

Earlier in March I traveled down to Famoso of Kern County to take the original alignment of California State Route 65 north to Lindsay in Tulare County.


This blog is a spin off of the below entry on the Southern Segment of current California State Route 65.

California State Route 65; South Segment

Part 1; The Stockton-Los Angeles Road, the East Side Line, and early California State Route 65 on Legislative Route 129

The corridor of CA 65 is closely aligned to the Sierra Nevada Foothills which first became a popular route of travel as part of the Stockton-Los Angeles Road.  The Stockton-Los Angeles Road came into use after the 1853 Kern River Gold Rush began.  The Stockton-Los Angeles Road was a replacement of the earlier El Camino Viejo.  Unlike El Camino Viejo the Stockton-Los Angeles Road avoided the dense Tule Marshes in San Joaquin Valley.  The Stockton-Los Angles Road stayed close to the Sierra Foothills near the new claims on the Kern River watershed.  The earlier El Camino Vi…
