Rock Creek Road (Calaveras County)

[Max Rockatansky]

Rock Creek Road is a 14.6-mile rural highway located in the Sierra Nevada foothills of Calaveras County.  The corridor begins at California State Route 4 near Main Street in Copperopolis and extends west to County Route J14 (Milton Road) in Milton via Salt Spring Valley.

Rock Creek Road is one of the oldest highways in Calaveras County.  The roadway came into common use during the 1850s to service the Madam Felix Mining District and early Salt Spring Valley Reservoir.  In 1871 the corridor would begin to service stages departing the terminus of the Stockton & Copperopolis Railroad in Milton.  Rock Creek Road would remain a major county highway through the 1930s until the railroad feeding it freight traffic went defunct in 1940.
