Siskiyou County Route A28; connecting the Southern Pacific Railroad sidings

Shasta Valley of Siskiyou County has several County Sign Routes.  One of the newest additions to the State Level County Sign Route network is Siskiyou County Route A28 which serves as a frontage facility to the numerous former Southern Pacific Railroad sidings of Shasta Valley.  

Siskiyou County Route A28 ("A28") is an approximately 23.5 mile highway connecting Siskiyou County Route A12 in Grenada north through Shasta Valley to Interstate 5 ("I-5") near Hornbrook.  A28 consists of the rail frontage roads of; Montague-Grenada Road, 11th Street in Montague, Montague-Ager Road, Ager Road, and Copco Road.  A28 serves the heart of Shasta Valley by providing direct highway access to the communities of; Grenada, Montague, Ager, and Hornbrook.  


Part 1; the history of Siskiyou County Route A28

The exact date of the establishment for A28 is unknown given it is a relatively new designation which does not appear in any known State record.  According to CAhighways.org A28 is a post-1983 County Sign Route given it was not in the established records from Caltrans.  Nonetheless the roads which make up A28 are very old and were established by the Southern Pacific Railroad when sidings were plotted out in Shasta Valley circa 1886-87.  The communities of; Grenada, Montague, Ager, and Hornbrook were all plotted by the Southern Pacific as frontage facilities along it's then new line in Shasta Valley.  Said communities can all be seen (in addition to Laird and Klamathon) along the Southern Pacific Railroad in Shasta Valley on the 1903 Rand McNally Map of California.  

The 1909 San Francisco Motor Club Map of the Yreka Area (courtesy Kevin Walsh of the Map Scans Facebook group) shows two routes from Yreka north towards the State Line.  The primary highway north of Yreka is shown to follow what is now Yreka-Ager Road and much of Siskiyou County Route A28 towards Hornbrook.  The secondary road is shown to follow what is now Anderson Grade Road from Yreka towards Hornbrook. 

The 1912 California State Automobile Map (courtesy Kevin Walsh of the Map Scans Facebook group) only shows present Yreka-Montague Road and Siskiyou County Route A28 as a highway between Yreka-Hornbrook.  Note; conjecture has it that early Legislative Route Number 3 ("LRN 3") may have been planned to follow much of what is A28. 

The current roads which comprise A28 all appear between Grenada and Hornbrook (yes, there was a community called Balls in Siskiyou County) on the 1917 California State Automobile Association Map.  LRN 3 is shown following what is now Anderson Grade Road towards Yreka instead of utilizing future A28 through Shasta Valley. 

The 1935 California Division of Highways Map of Siskiyou County provides more detail regarding future A28.  Most of future A28 (from Grenada to Ager) is shown as a major County Highway.  




Part 2; a drive on Siskiyou County Route A28

A28 begins from A12/99-97 Cutoff in Grenada via a turn northward onto Montague-Grenada Road.  Montague is signed as 5 miles north of Grenada. 

A28 initially tracks east of the Central Oregon & Pacific Railroad ("COPR") on Montague-Grenada Road.  Approximately 4 miles from Grenada A28 northbound crosses over to the western side of the Union Pacific approaching Oberlin Road.  Note; The rail route through Shasta Valley is presently operated by the COPR which was sold by the Southern Pacific in 1994.







A28 north of Oberlin Road crosses the Shasta River and enters the City of Montague on 11th Street.  A28 north picks up California State Route 3 ("CA 3") at Montague Road and beings a rare State Highway/County Sign Route multiplex.  





The Montague Depot Museum can be found on CA 3/A28 on 11th Street.  As noted above Montague was plotted out as a Southern Pacific Railroad siding in 1887.  Montague was named after a engineer from the Central Pacific Railroad and incorporated as a City in January of 1909.  The Montague Depot was constructed over a five week period in 1887 and is presently located at the intersection of 11th Street/King Street.  The Montague Depot was originally located on Webb Street on the east side of the COPR tracks.  

 

At Webb Street CA 3 splits east towards a terminus at the edge of the Montague City Limits.  A28 continues north to the City Limit of Montague and transitions onto Montague-Ager Road upon crossing Oregon Slough. 


A28 north of Montague follows the western side of the COPR and has a major intersection at Yreka-Ager Road.  A28 at Yreka-Ager Road is signed as 15 miles from Hornbrook. 

A28 follows Willow Creek and the COPR to the outskirts of Ager approximately 10 miles north of Montague.  

A28 transitions onto Ager Road and continues north towards the Klamath River.  A28 crosses over the COPR and Klamath River at Klamathon Road.  Upon crosses the Klamath River A28 swings westbound onto Copco Road towards I-5, Hornbrook is signed as 3 miles away.



A28 approaches the outskirts of Hornbrook at Roy Jones Road.  West of Roy Jones Road A28 crosses the COPR. 


Upon crossing the COPR A28 intersects Hornbrook Road.  Access to Hornbrook is signed north on Hornbrook Road whereas A28 traffic is directed to stay west to reach I-5.  

A28 terminates at I-5 in the community of Henley.

Former California State Route 1 over Old Pedro Mountain Road

California State Route 1 in western San Mateo County traverses the Montara Mountain spur of the Santa Cruz Mountains.  In modern times California State Route 1 passes through Montara Mountain via the Tom Lantos Tunnels and the highway is traditionally associated with Devils Slide.  Although Devils Slide carries an infamous legacy due it being prone landslides it pales in comparison to the alignment California State Route 1 carried prior to November 1937 over Old Pedro Mountain Road.   Old Pedro Mountain Road opened to traffic in 1915 and is considered one of the first major asphalted highways in California.  Old Pedro Mountain Road clambers over a grade from Montara towards Pacifica via the 922 foot high Saddle Pass.  Pictured above an overlook of Old Pedro Mountain Road facing southward towards Montara as it appears today.  Pictured below it the same view during June 1937 when it was part of the original alignment of California State Route 1.  Today Old Pedro Mountain sits abandoned a

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard.  The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio.  This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951.  Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232.  Of n

Former US Route 101 and California State Route 1 in San Luis Obispo

Originally US Route 101 upon descending Cuesta Pass southbound entered the City of San Luis Obispo via Monterey Street.  From Monterey Street US Route 101 utilized Santa Rosa Street and Higuera Street southbound through downtown San Luis Obispo.  Upon departing downtown San Luis Obispo US Route 101 would have stayed on Higuera Street southward towards Pismo Beach and Arroyo Grande.  Notably; beginning in 1934 US Route 101 picked up California State Route 1 at the intersection of Monterey Street/Santa Rosa Street where the two would multiplex to Pismo Beach.  Pictured below is the 1 935 Division of Highways Map of San Luis Obispo County depicting the original alignments of US Route 101 and California State Route 1 in the City of San Luis Obispo.   Part 1; the history of US Route 1 and California State Route 1 in San Luis Obispo San Luis Obispo lies at the bottom of the Cuesta Pass (also known as the Cuesta Grade) which has made it favored corridor of travel for centuries.  Cuesta Pass
