State Route 178 (SR 178) is a route that exists in two constructed segments. The gap in between segments is connected by various local roads and State Route 190 through Death Valley National Park.

This route is part of the California Freeway and Expressway System [ CA Codes (shc:250-257)] ] and is eligible for the State Scenic Highway System [ CA Codes (shc:260-284)] ] .

Route description

Western segment

The first segment starts at State Route 99 just west of Downtown Bakersfield. The road continues as 24th street, but then splits at B St. utilizing 24th street as its westbound usage, and 23rd St. as its eastbound through the eastern part of Downtown Bakersfield. 178 then becomes a freeway as it departs Bakersfield. The freeway ends about convert|5|mi|km east of Downtown and becomes a two-lane conventional highway that ascends the lower Sierra Nevada Mountains on its way to Lake Isabella. Just south of Lake Isabella, the road briefly again becomes a divided limited access freeway, but later converts back to a two lane road at the at-grade junction with Lake Isabella Blvd. The road winds a little bit until it ascends to Walker Pass, an elevation of over convert|5000|ft|m. The highway then descends from the mountains to its junction with State Route 14. It then proceeds eastward across US 395 into the town of Ridgecrest, CA. The constructed highway ends at the turnoff for the Trona Pinnacles National Natural Landmark.

Eastern segment

The second segment resumes four miles (6 km) west of Salisberry Pass in the southeasterly part of Death Valley National Park in Inyo County at what had been the former boundary of Death Valley National Monument until 1994. It then meets up with State Route 127. 178 then branches northward from 127 to the California-Nevada State Line. In Nevada, the roadway continues as State Route 372 ending at State Route 160 near the center of Pahrump in Nye County. Plans to connect the two constructed segments in California are unlikely due to the would-be link's passage through Death Valley National Park.

The segment of State Route 178 from State Route 127 to the California-Nevada State Line as well as all of Nevada State Route 372 are both known as the Charles Brown Highway. Charles Brown, a former California State Legislator, was a major proponent for the incorporation of the segment of State Route 178 between State Route 14 and the California-Nevada state line into the California Highway System.

Major intersections and exit list

:"Note: Except where prefixed with a letter, postmiles were measured in 1964, based on the alignment as it existed at that time, and do not necessarily reflect current mileage. The numbers reset at county lines; the start and end postmiles in each county are given in the county column."
