State Route 178


Scenic California State Route 178 leads east through the Kern River Canyon, which is a narrow canyon crafted by the waters of the Kern River. Falling rocks are a concern along certain sections of the highway. Photo by Erik Fox. - 10/15/2006
California 178 begins at the Junction of California 58 and California 99 in Bakersfield. After passing California 204 & California 99 Business (Golden State Highway), California 178 briefly becomes a freeway before heading northeast toward the Sierra Nevada foothills along the banks of the Kern River.
Through the Kern River Canyon and over Walker Pass, California 178 is the only all-weather trans-Sierra route between California 58 and California 88. Passing by Isabella Reservoir, California 178 crosses Walker Pass (el. 5,245 feet) before meeting California 14 and U.S. 395 in the vicinity of Ridgecrest and China Lake.
Currently, the western segment of California 178 ends near the community of Trona northeast of Ridgecrest. There is a route gap between the western and eastern segments due to Death Valley National Park. The detour around the route gap is made via local roads and California 190 through the park. The endpoint for the western section of California 178 is at the turnoff to the Trona Pinnacles National Natural Landmark. The highway continues as a county-maintained highway, initially by San Bernardino County and then by Inyo County. The county route turns north, and it ultimately meets California 190 just east of Panamint Springs within Death Valley National Park, as shown in the Death Valley map. There are standing proposals to connect California 178 near Trona with the eastern section of California 178, but that seems increasingly unlikely given the fact that much of this unconstructed route lies within Death Valley National Park.
The eastern segment of California 178 emerges as a narrow, two-lane highway at what seems to be an arbitrary point, but it is actually the original Death Valley National Monument (predecessor to the expanded Death Valley National Park) boundary south of Badwater Basin (lowest spot in the continental United States) near Jubilee Pass. California 178 continues through Death Valley National Park, finally meeting California 127 a few miles north of Shoshone. California 178 merges onto California 127 for the distance into Shoshone, then turns northeast to cross into Nevada en route to Pahrump via Nevada 372.
