Signed County Route E15 to Copperopolis

Back in 2016 I frequently used Signed County Route E15 as a short cut from California State Route 108/120 in Tuolumne County to CA 4 in Calaveras County.


E15 is a 12.91 mile long Signed County Route which was defined in 1974 according to CAhighways.org.

On the Tuolumne County side E15 begins from CA 108/120 at O'Byrne's Ferry Road.  Traffic is warned along CA 108/120 not to pick up hitch hikers due to the a corrections center which is oddly placed next to the Sierra Conservation Center on the Tuolumne County side of E15.


E15 is one of the better Signed County Routes in terms of signage.  While some of the shields are old they are generally well placed in a logical enough way to convey to the traveler they are on E15 which can be a rarity at times among the Signed County Routes.


E15 on O'Brynes Ferry Road descends to the Tulloch Reservoir which serves as the Calaveras County Line.  The Tulloch Reservoir impounded a small section of the Stanislaus River which once crossed by O'Bryne's Ferry in 1958 when Tulloch Dam was completed.  The O'Byrne's Ferry first opened as a cable ferry crossing of the Stanislaus River in 1852.  The first O'Byrne's Ferry Bridge opened in 1852 and was replaced numerous times in the ensuing decades due to flooding on the Stanislaus River.  The article below contains a picture of the 1863 Union Covered Bridge which used to occupy the site.

E15 in Calaveras County ascends a small bluff from the Tulloch Reservoir on O'Brynes Ferry Road.  Interestingly the Postmile paddles in Calveras County resemble those from Caltrans which makes E15 on O'Byrnes Ferry Road appear as it on "CA 48" at casual glance.


Near the north terminus E15 enters Copperopolis on Main Street.  Copperopolis was founded in 1860 and was the second major copper strike in Calaveras County after Telegraph City to the west.  During the Civil War the copper mines in Copperopolis closed but they reopened in the 1880s ensuring the community survived.  Copperopolis largely has been replaced by a modern and in my opinion garish looking facade of a Gold Rush era town to the west along CA 4 but there are a couple authentic buildings located on E15.  The Copperopolis Armory dates back to 1864 and saw use in during the Civil War.  Reed's Store dates back to 1861 and was once the headquarters of the Union Mining Company in 1906.





E15 ends at CA 4 in Main Street in Copperopolis.

Yes, the color of your nearby fire hydrant matters...

...and here's why. You will find White, Red, Yellow and Violet colored fire hydrants pretty much everywhere.  But there's a reason for this - and it's because of the National Fire Protection Association (NFPA).  This association has issued guidelines for color coding standards for fire hydrants.  These color codes from the body of the hydrant, top of the hydrant, and in some municipalities the outlet caps are designed to allow fire fighters to know what type of system, water flow rate (Gallons Per Minute or GPM), and level of water pressure.  This guideline is known as NFPA 291 and is intended to be used universally throughout the United States. The NFPA guidelines are specific to the body and the top cap of the hydrant.  If a hydrant is WHITE or YELLOW - it means that it is connected to a public/municipal water system.  If a hydrant is RED - the hydrant is connected to a private system, typically a well.  These are most common in rural or unincorporated areas

Legend of the Ridge Route; a history of crossing the mountains between the Los Angeles Basin and San Joaquin Valley from wagon trails to Interstates

Over the past two decades I've crossed the Interstate 5 corridor from Los Angeles north over the Sierra Pelona Mountains and Tehachapi Range to San Joaquin Valley what seems to be an immeasurable number of times.  While Interstate 5 from Castaic Junction to Grapevine via Tejon Pass today is known to most as "The Grapevine" it occupies a corridor which has been traversed by numerous historic highways.  The most notable of these highways is known as the "Ridge Route."  This article is dedicated to the Ridge Route and the various highways that preceded it.  This blog is part of the larger Gribblenation US Route 99 Page.  For more information pertaining to the other various segments of US Route 99 and it's three-digit child routes check out the link the below.

Establishing the numbering conventions of California's chargeable Interstates

The Federal Highway Aid Act of 1956 brought the Interstate Highway System into existence which would largely be constructed by Federal Highway Administration fund matching.  The Interstate Highway System was deliberately numbered to run opposite the established conventions of the US Route System.  While the Interstate Highway numbering conventions are now well established there was a period during the late 1950s where they were still being finalized.  This blog examines the history of the establishing of the chargeable Interstate Highway route numbers in California.  The above blog cover depicts the Interstate Highway route numbers requested by the Division of Highways in the Los Angeles area during November 1957.  The establishment of the numbering conventions of California's chargeable Interstates The Interstate Highway System was not created in a vacuum by way of the passage of the 1956 Federal Highway Aid Act.  The beginning of the Interstate Highway System can be found in the
