California State Route 52

A recent acquisition in sign collecting renewed my interest in revisiting the history of a freeway I used to frequently drive in northern San Diego; California State Route 52.


CA 52 is a 17.22 mile freeway which connects Interstate 5 in San Diego east to CA 67 in Santee.



Part 1; The History of California State Route 52

The history of CA 52 is fully documented on stub page for the highway on CAhighways.org.   The origin of what became CA 52 was in 1959 when Legislative Route Number 279 was added as a planned highway between La Jolla and Santee.  LRN 279 can be seen for the first time on the 1960 Division of Highways State Map City Insert as a planned highway.


According to CAhighways.org the alignment of LRN 279 between what is now I-5 and I-805 was formally adopted in 1962.  The formal route adoption of LRN 279 between I-5 and I-805 can be seen on the 1963 Division of Highways State Map City Insert.


During the 1964 State Highway Renumbering all Legislative Route Numbers were dropped.  LRN 279 was replaced with the designation of CA 52 which can be seen on the 1964 Division of Highways State Map City Insert.


According to CAhighways.org CA 52 between I-5 and I-805 opened during 1970.  The 1970 Division of Highways State Map City Insert shows CA 52 under construction between I-5 and I-805 whereas the 1975 Caltrans State Map City Insert shows it open.  According to CAhighways the planned route of CA 52 east to I-15 was formally adopted in July 1972 (which can be seen on the 1975 Caltrans Map).



CA 52 was opened east to I-15 in 1988 according to CAhighways and can be seen on the Caltrans State Map City Insert from said year.


According to CAhighways.org the formally planned alignment of CA 52 east to CA 67 was adopted in July of 1989.  CA 52 was completed to Mast Boulevard in 1993 and to CA 125 by November 1998.  CA 52 can be seen on the 2005 Caltrans State Map City Insert opened to CA 125.


CA 52 was completed to CA 67 during the Spring of 2011.  Unfortunately 2005 was the last year Caltrans published a State Highway Map hence why there is no accompanying image below.  CA 52 today is known as the Soledad Freeway but was known as the San Clemente Freeway previously.


Part 2; Some Road Scenes Related to CA 52

As noted above I recently acquired a CA 52 shield for my sign collection.  There was a button-copy variation available but the standard shield was only one third of the price.


Most my drives on CA 52 were during 2011-2013 when I was working frequently in Southern California.  Most of my photo stock from those times was lost in a hard drive crash in 2013.  I recently took some photos related to CA 52 in April/May of 2019.  These photos below were taking from I-5 north approaching the CA 52 interchange.





Below are photos of I-805 southbound approaching the interchange with CA 52.

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.

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.

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…

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&#…
