The early alignments of CA 4 in Copperopolis and Telegraph City

[Max Rockatansky]

The Calaveras County communities of Copperopolis and Telegraph City are located in region of the Sierra Nevada foothills which went through a copper mining boom starting in the 1860s.  When California State Route 4 was commissioned in 1934 it followed the corridor of Reed's Turnpike through Telegraph City to Main Street in Copperopolis.  Both communities were bypassed during the late 1970s, but California Transportation Commission shelved plans to modern the highway east to Altaville (not part of Angels Camp).  Recently the Wagon Trail Realignment Project between Copperopolis and Angels Camp has been revived as is currently in construction as of the publishing of this blog.
