San Juan Pacific Railway

This past month I stopped in San Juan Bautista of San Benito County to view a historic plaque detailing the history of the San Juan Pacific Railway.


The San Juan Pacific Railway historic plaque is located on former Legislative Route 22/Old San Juan-Hollister Road just east of The Alameda in the City of San Juan Bautista.  The San Juan Pacific Railway plaque is located atop it's former grade.




As noted above the San Juan Pacific Railway ("SJPR") incorporated in 1907 but it only briefs the story of the line.  The San Juan Pacific Railway was standard gauge line built to connect from the Southern Pacific Railroad in Chittenden of Santa Cruz County 7.94 miles southeast to a concrete processing facility in San Juan Canyon near San Juan Bautista.  Said Portland Cement processing facility in San Juan Canyon was originally owned by the San Juan Cement Company which began operations in 1907.

The San Juan Cement Company was not successful and shuttered operations in late November of 1907.  The assets of the San Juan Cement Company were eventually taken over by the Old Mission Cement Company in May of 1912.  The Old Mission Cement Company rebranded the SJPR into the Central California Railroad.  The Old Mission Cement Company built a narrow-gauge quarry line east of the processing facility deeper into San Juan Canyon.  The first cement shipments began rolling from San Juan Canyon in 1916 but it wasn't until 1918 that the Old Mission Cement Plant was complete.

The Old Mission Cement Plant extended its quarry line another 1.5 miles to two new quarries in 1921.  The Old Mission Cement Plant sold out to the Pacific Portland Cement Company in 1927.  The Pacific Portland Cement Company announced it intended to add three additional miles of quarry line in 1929.  The Pacific Portland Cement Company shuttered operations in 1930 due to the economic conditions of the Great Depression.  In 1937-1938 (sources conflict) the standard gauge rails of the Central California Railroad were removed.  The cement processing facility reopened in 1941 under the banner of Ideal Cement which operated to the 1970s when the cement plant was dismantled.

Note; much of the above information on the history of the SJPR was sourced from an article on PacificNG.org on the Old Mission Portland Cement Company.

A limited number of maps show the SJPR.  One such map was the 1920 Denny's Pocket Map of San Benito County which shows the SJPR line ending in San Juan Canyon.


The SJPR also appears on the 1935 California Division of Highways Map of San Benito County.


The alignment of the SJPR is sketched onto the two maps (in brown) below which I drew to show historic transportation corridors around San Juan Bautista.



There is still some existing evidence of the SJPR which can be seen along County Route G1.  I took the below photo in 2017 which shows the grade of the SJPR to the left of County Route G1 on San Juan Canyon Road.


As County Route G1 transitions onto Mission Vineyard Road a set of embedded rails can be seen in the roadway.


In early 2020 I returned to County Route G1 on Mission Vineyard Road to get better photos of the embedded rails.

Morgan Territory Road

Morgan Territory Road is an approximately 14.7-mile-long roadway mostly located in the Diablo Range of Contra Costa County, California.  The roadway is named after settler Jerimah Morgan who established a ranch in the Diablo Range in 1857.  Morgan Territory Road was one of several facilities constructed during the Gold Rush era to serve the ranch holdings.   The East Bay Regional Park District would acquire 930 acres of Morgan Territory in 1975 in an effort to establish a preserve east of Mount Diablo. The preserve has since been expanded to 5,324 acres. The preserve functionally stunts the development along roadway allowing it to remain surprisingly primitive in a major urban area. Part 1; the history of Morgan Territory Road During the period of early period of American Statehood much of the Diablo Range of Contra Costa County was sparsely developed.   Jerimah Morgan acquired 2,000 acres of land east of Mount Diablo in 1856 and established a ranch in 1857.

Interstate 210 the Foothill Freeway

The combined Interstate 210/California State Route 210 corridor of the Foothill Freeway is approximately 85.31-miles.  The Interstate 210/California State Route 210 corridor begins at Interstate 5 at the northern outskirts of Los Angeles and travels east to Interstate 10 in Redlands of San Bernardino County.  Interstate 210 is presently signed on the 44.9-mile segment of the Foothill Freeway between Interstate 5 and California State Route 57.  California State Route 210 makes up the remaining 40.41 miles of the Foothill Freeway east to Interstate 10.  Interstate 210 is still classified by the Federal Highway Administration as existing on what is now signed as California State Route 57 from San Dimas south to Interstate 10.  The focus of this blog will mostly be on the history of Interstate 210 segment of the Foothill Freeway.   Part 1; the history of Interstate 210 and California State Route 210 Interstate 210 (I-210) was approved as a chargeable Interstate during September of

Clovis "Gateway To The Sierras" sign and Tarpey Depot

Within Oldtown Clovis a fixture of the original alignment of California State Route 168 can be found in the form of the  "Clovis Gateway To The Sierras" sign. The sign was erected along Clovis Avenue in 1940 and was in use along California State Route 168 until the highway was relocated circa 1999-2001. Nearby Tarpey Deport can be found at the northeast corner of Clovis Avenue and 4th Street. The depot was constructed in 1892 as part of the San Joaquin Valley Railroad between Fresno and Friant. The depot structure was one previously located at the southeast corner of Clovis Avenue and Ashlan Avenue. Part 1; the history of the Gateway To The Sierras sign The "Clovis Gateway To The Sierras" sign located in Oldtown Clovis along Clovis Avenue between 4th Street and 5th Street. During 1933 Legislative Route Number 76 was extended with a second segment plotted between Huntington Lake and Fresno. The new segment passed through Oldtown Clovis westbound via Tollhouse R
