The route of US 395 in California is split into two segments, as the highway exits and reenters California via Nevada. The southern segment crosses the Mojave Desert and Owens Valley and passes east of the Sierra Nevada. The northern segment also follows the Sierra Nevada and crosses the Modoc Plateau.[3]
US 395 is part of the California Freeway and Expressway System,[4] and part of the National Highway System,[5] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[6] US 395 is eligible to be included in the State Scenic Highway System,[7] and is officially designated as a scenic highway by the California Department of Transportation from Fort Independence to Fort Springs Road in Inyo County, and from the Inyo–Mono county line to south of Walker.[8] This designation means that there are substantial sections of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community.[9]
Mojave Desert
US 395 in the Mojave Desert near Victorville
US 395 begins in Hesperia at a partial interchange with I-15 as it heads north. The road then enters Adelanto, on the western edge of Victorville. Victorville, founded by the Santa Fe Railroad to take advantage of water along the Mojave River, and for most of its history home to George Air Force Base,[10] was the second fastest growing city in the United States from July 2006 to July 2007.[11] Although US 395 was once a rural road passing to the side of these cities, with growth these cities are encroaching on the highway and changing its character from rural to suburban.
After leaving the Victorville area, the scenery changes as suburban neighborhoods disappear and the highway traverses the Mojave Desert. While crossing the desert, the route clips the northeastern corner of Edwards Air Force Base. Just past the base, the road intersects State Route 58 (SR 58) at Kramer Junction. This was formerly an at-grade intersection; however, SR 58 was rerouted onto a new freeway alignment on October 24, 2019.[3][12]
After leaving Kramer Junction, US 395 passes the Kramer Junction Solar Electric Generating Station.[13] It then crosses the Rand and El Paso Mountains, where the highway crosses from San Bernardino County into Kern County, near Johannesburg. While traversing these mountains, the route crosses a former Southern Pacific rail line, now owned by the Union Pacific Railroad (UP) that loosely follows the route of SR 14 through the Mojave. Though the railroad is abandoned north of Searles Station, US 395 parallels the old railroad grade from this point to Lone Pine.[3][14]
On the other side of the mountains is Indian Wells Valley. US 395 passes between the cities of Ridgecrest and Inyokern, where US 395 Business is routed on South China Lake Boulevard.[15]
US 395 follows the western boundary of the Naval Air Weapons Station China Lake, not far from Big and Little Petroglyph Canyons, where the Coso People created prolific rock art and traded with distant tribes using tools crafted of stone.[16] The highway proceeds diagonally across the valley, until merging with SR 14. Prior to July 1, 1964, the part of SR 14 between I-5 and US 395 was part of US 6 that continued south to Long Beach.

Between Mojave and its junction with US 395, SR 14 follows the edge of the Sierra Nevada mountains. Formerly, US 6 and US 395 ran concurrently from this junction north to Bishop. US 395 follows the valleys along the eastern edge of the Sierra Nevada as the mountains gradually increase in altitude until reaching their peak at over 14,000 feet (4,300 m) near Lone Pine.[3] After passing by three small lakes, Little Lake and North and South Haiwee Reservoirs, the highway enters the Owens Valley.
Owens Valley
US 395 traverses the entire length of the Owens Valley, entering the valley near the former site of the Owens Lake. The valley, named for one of explorer John C. Fremont's guides, was primarily home to the Timbisha and Paiute peoples before European settlement. Formerly a fertile lake and valley, Owens Lake and the southern portion of the valley are now dry. Water from the valley is channeled for use by the City of Los Angeles, via the Los Angeles Aqueduct, which was constructed during what is commonly called the California Water Wars.[17]
Along the shores of Owens Lake, the highway passes by Cartago and Olancha. Just north of the lake is Lone Pine. Lone Pine is noted as an access for both the highest point in the contiguous United States, Mount Whitney, and the lowest point in North America, Badwater Basin in Death Valley. Both Mount Whitney and the mountains surrounding Death Valley are visible from US 395.[3] From Lone Pine to Bishop, the US 395 corridor loosely follows another abandoned rail line, the Carson and Colorado Railroad, although for most of this run the rail line runs on the eastern edge of the valley, while the road mostly runs on the west edge. The US 395 corridor from Lone Pine north to the Nevada state line is noted for a high concentration of natural hot springs leading to the area being known as the "hot springs jackpot".[18]
Truck passing through Owens Valley with the Sierra Nevada in the background
At the north end of the valley sits Bishop, the largest city in the Owens Valley. Bishop serves as a gateway for the recreation areas of the Sierra Nevada, including Mammoth Mountain. At the north end of Bishop is the former separation with, and current terminus of, US 6, a 3,205-mile (5,158 km) route which travels eastward across the US to Provincetown, Massachusetts on the east coast. This point is also where US 395 departs from former rail corridors, with the former Carson and Colorado grade following the modern US 6 corridor towards Hawthorne and Tonopah, Nevada.[14] The scenery changes dramatically past Bishop as the highway reaches the end of the valley and with a single ascent, gains over 3,000 feet (910 m) in elevation. From here to Gardnerville, the highway is routed across spur ranges of the Sierra Nevada mountains.[3]
US 395 scales the Sierra Nevada on a ridge between the canyons of the Owens River and Rock Creek. Sherwin Summit, at 7,000 feet (2,100 m), is the first of five mountain passes crossed by US 395 in the Sierra Nevada. The highway enters Mono County midway up the ascent, which is known as the Sherwin Grade.[3]
After cresting Sherwin Summit, the highway travels along the west shore of Crowley Lake. Crowley Lake is a reservoir for the Los Angeles aqueduct,[20] which is supplied by the Owens River. However, US 395 does not resume following the river, instead cutting across the Long Valley Caldera to serve the ski resort areas of Mammoth Lakes and Mammoth Mountain via SR 203, after paralleling the runway of the Mammoth Yosemite Airport.
Eight miles (13 km) past the junction leading to Mammoth, the highway crests the second summit, Deadman Summit, at 8,036 feet (2,449 m). This summit separates the Owens River watershed from that of Mono Lake, a salt lake approximately three times as salty as the ocean.[21]
Just before arriving at Mono Lake, US 395 has a brief concurrency with SR 120; the two routes separate at the southern end of Lee Vining. At this junction US 395 is 12 miles (19 km) from Tioga Pass, along SR 120, the highest paved through route in California, and the eastern boundary of Yosemite National Park.[3]
Visible for miles, the highway finally passes Mono Lake, squeezed between the lake and the Sierra crest. The next geographic feature is Conway Summit. At 8,138 feet (2,480 m) in altitude, this is the highest point along US 395, and the highest point along a U.S. Highway in California. This Summit also separates the Mono Lake watershed from that of the East Walker River.[3]
The highway descends Conway Summit via the tributaries of the East Walker River, heading towards Bridgeport and Bridgeport Reservoir. Along the descent the highway passes by a turnoff to Bodie, a ghost town which the state park system has preserved, including items still on the shelves in the abandoned stores.[22]
The fourth summit crossed by US 395 in California is Devil's Gate Pass, elevation 7,519 feet (2,292 m), which separates the East and West Walker Rivers. The winding descent from Devil's Gate follows the West Walker River, exiting near the towns of Walker and Coleville in the Antelope Valley, a few miles south of Topaz Lake which is on the California-Nevada State Line.
Topaz Lake is where US 395 leaves California, to serve the Reno and Carson City metropolitan areas before returning to California. The highway runs for 87 miles (140 km) in Nevada, with a significant portion built to freeway standards and co-designated Interstate 580.[23] When the highway passes from California to Nevada it is near the area where the larger Sierra Nevada in California separates from the Pine Nut Mountains of Nevada. The highway crosses one more pass, Simee Dimeh Summit, before completely exiting the mountains. The highway returns to California following the receding escarpment of the Sierra.[3]
The highway enters the state in a corner of Sierra County, entering Lassen County just 3 miles (4.8 km) later. A short segment in Lassen County is a freeway with one exit serving SR 70 at the Hallelujah Junction. This exit is numbered 8, even though it resides hundreds of miles from the origin of the highway; the exit number instead uses the distance from the point of re-entry to California.[24] Though SR 70 does not directly serve any major cities, the highway is noted as an all-weather crossing of the Sierras. Just less than 5 miles (8.0 km) from Hallelujah Junction is Beckwourth Pass, the lowest pass in the Sierra, used by both SR 70 and the Feather River Route.[25] SR 70 was at one time numbered U.S. Route 40 Alternate, using US 395 from this junction south to Reno to connect with the mainline US 40 (now I-80). Though using US 40 ALT and US 395 is a much longer route between Reno and Sacramento than mainline US-40 (130 miles (210 km) versus 226 miles (364 km)),[26][27] the alternate route was more likely to be open during winter storms than US 40, which crested the Sierra at Donner Pass.
The highway proceeds towards and around the west side of 73-square-mile (190 km2) Honey Lake while en route to Susanville. Although Susanville is used as a control city, US 395 does not technically enter the city. In a T-intersection with SR 36 just before Susanville, US 395 makes a sharp turn avoiding the city, making a near complete loop around the Susanville Municipal Airport.[28]
Modoc Plateau
North of Susanville, the highway bends around Shaffer Mountain and crosses the Modoc Plateau. While en route, the highway serves the towns of Ravendale, Termo, and Madeline in Lassen County, as well as Likely in Modoc County. Here US 395 parallels the South Fork of the Pit River until the confluence with the north fork in Alturas. Past the confluence, the highway follows North Fork Pit River across Modoc County toward Goose Lake. The last junction in California is with SR 299, former U.S. Route 299, in Alturas. SR 299 can be used to travel west all the way to the western side of California at US 101 in Arcata, and east to Nevada State Route 8A at the Nevada state line. The two highways are briefly concurrent from Alturas to the XL Ranch Indian Reservation. US 395 travels in a north-northeast direction for the last 50 miles (80 km) in California, paralleling the east shore of Goose Lake just before crossing the Oregon state line at New Pine Creek, Oregon.[19]
The Camino Sierra was a trail from Los Angeles to Lake Tahoe loosely paralleling modern State Route 14, US 395, and State Route 89. The trail was first believed to be used by Jedediah Smith in 1826. The trail was in common use by prospectors passing through the area because of the California gold rush and Comstock Lode. Though this area was not directly affected by the gold and silver rushes, the Owens Valley was more fertile than the areas around the strikes in Nevada. Farmers and ranchers raised cattle and other goods to trade with the mining boom towns nearby. The town of Bishop was established to trade goods with the mining town of Aurora.[29] By 1860, the Camino Sierra was an established trail appearing in maps and guides. After these mining rushes died down, the Camino Sierra saw a revival because of the construction of the Los Angeles Aqueduct beginning in 1908. The route was promoted for its scenic value by the Southern Pacific Railroad, as a side trip from its rail lines, as far back as 1912.[30] By 1918, the Camino Sierra had been included in the Automobile Blue Book, an early road atlas of the United States.[31]
Rail lines
Both the northern and southern segments of the US 395 corridor were used by railroads built in the 1880s branching from the First transcontinental railroad in Nevada. Both lines were intended to connect the main Southern Pacific Railroad line in Nevada with other lines, but were never completed.
On May 20, 1880, the Carson and Colorado Railway was formed, with the intent of extending a rail line from the existing Virginia and Truckee Railroad at Mound House, Nevada through the Owens Valley towards the Colorado River. Though the rail line was never finished, it did bring economic development to the valley. The railroad was never completed past Keeler on the shores of Owens Lake.[32] This line was acquired by the Southern Pacific Railroad in 1900. There were plans to connect this narrow gauge line with SP's standard gauge lines in the area, however these plans never materialized and the narrow gauge line was scrapped in 1959.[32][33]
The corridor for the northern segment was first used by the Nevada-California-Oregon Railway, a line also started in 1880, at Reno, to connect with the Great Northern Railway in Oregon.[33] This line also was never completed, ending at Lakeview, Oregon. A portion of this line is still active and, through a series of acquisitions, the Union Pacific Railroad now owns this line. The portion from Reno to Hallelujah Junction is used as a connection between the Union Pacific's two main lines in northern California/Nevada, the Overland Route (First Transcontinental Railroad) and the Feather River Route.[3]
As first commissioned in 1926, US 395 was a minor spur route of U.S. Route 195 connecting Spokane, Washington with Canada.[34] During the 1930s, US 395 was extended from Spokane to San Diego, over the Camino Sierra, using several existing state routes. The extension first appeared on the Official Nevada Highway map in 1935 and its Californian equivalent in 1936.[35][36] By 1937, US 6 had been extended to California, concurrent with US 395 between Bishop and Inyokern.[35]
The new southern terminus of US 395 was at Pacific Highway (former US 101) in San Diego. Traveling north, US 395 traversed much of the path of modern SR 163 and I-15 to Poway Road, where it routed to the east along much of today's Pomerado Road to Lake Hodges, with various realignments over the years. Portions of Pomerado Road today are signed "Historic US 395". At Lake Hodges the highway crossed a now-replaced bridge to Escondido.
Past Escondido, the route passed through Fallbrook, using portions of what is now SR 78 and SR 76 before returning to I-15 near Temecula.[37] This portion was straightened to the route of modern I-15 by 1960.[38] Past Temecula, the route followed SR 71, SR 74, I-215, and I-15 until reaching the modern terminus in Hesperia.[38] This part would also be straightened with the construction of what is now I-215. In 1969, the portion south of Hesperia was removed and assigned to other routes.[39]
Over time, the road was paved, upgraded and straightened. Some parts are now built to freeway standards. Among the more notable upgrades, the Los Peñasquitos Creek Arch Bridge, along the portion of former US 395 now used by I-15, was built in 1949, and replaced in 1964, with a second span built in 1977.[40]

Future
Currently US 395 runs as a surface street through most of the cities and towns it serves. However, numerous proposals for bypasses of several of the towns along the route have been proposed, with varying degrees of progress since first proposal. Proposals with no current construction include longstanding proposals to bypass Bishop, [41] and a freeway bypass of the current surface route through Adelanto, Victorville, and Hesperia.
In 2022, construction began on a bypass of Olancha and Cartago,[42] which has been controversial as most residents preferred improving the existing route.[43] Once finished, the northern portion, through Cartago, is proposed to become a county route while the southern portion, through Olancha, would become an extension of SR 190.[44] Southbound traffic was shifted onto the bypass on October 7, 2024,[45] while northbound traffic was shifted onto the bypass in November 2024. SR 190's new connection with the bypass southeast of Olancha is still currently under construction.[46]
With the fast growth of the Victorville area, Caltrans and the county governments have noted a dramatic increase in congestion and accidents along the route. While short-term fixes are in progress to increase capacity,[47][48] the governments note the numerous fixes already implemented along US 395 have failed to reduce congestion or increase safety and a freeway bypass is likely needed.[49] The frustration over a lack of progress on a freeway bypass of the Victorville area has led to community protests and petitions to accelerate progress for a freeway alignment of US 395.[50]
Major intersections
Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see California postmile § Official postmile definitions).[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
U.S. Route 395 Business (US 395 Bus.) is a business route of US 395 in Ridgecrest. It provides access to Ridgecrest as China Lake Boulevard and Inyokern Road. Part of the route is concurrent with State Route 178.
