California 18

Routing

California 18 begins its northerly journey at California 210 (Former California 30) in San Bernardino. It enters the San Bernardino National Forest, then it turns east to follow the Rim of the World Highway part Lake Arrowhead and Big Bear Lake. From Big Bear, it turns north toward the desert, then turns west at Lucerne Valley to connect with Interstate 15 at Victorville. The route then ends at California 138 west of Interstate 15. The entire route looks like a backward "C" on the map, and it is not the fastest route between its two endpoints. However, it is the primary route near the skiing resorts near Big Bear. Cardinal direction banners are uncommon on the reassurance shield assemblies along California 18 since the route changes directions several times along its circuitous route.

Highway Guide

California 18 OUTER LOOP (Counterclockwise) from California 210 to California 138
California 18 (outer) north
California 18 currently begins its northbound journey at the interchange between California 210/Foothill Freeway and Waterman Avenue in San Bernardino. At the time this photo was taken, California 210 was still signed as California 30; this has since been changed to California 210. The Waterman Avenue interchange marks the southern terminus of California 18; the legislative state Streets and Highways Code call for an extension of California 18 south along Waterman Avenue (potentially as a freeway) to Interstate 10, but no plans exist for constructing the extended state route. Photo taken 06/24/07.
After crossing over California 210, northbound California 18 meets 30th Street. Turn left here for California 210 west to Interstate 215. Continue straight ahead for California 18 north to Crestline, Lake Arrowhead, and mountain resorts above San Bernardino. Photo taken 06/24/07.
From its beginning at California 210, northbound California 18 ascends toward Lake Arrowhead and Big Bear Lake along a four-lane highway. These pictures show the road along northbound at varying intervals as it approaches California 138. The speed limit generally remains 60 miles per hour on the entire northbound trek, with some exceptions. In some spots along the way, bridges were constructed to make California 18 four lanes. After the California 138 interchange, California 18 becomes a two-lane rural highway. Photos taken 05/02/02.
Northbound California 18 meets Junction California 138 near Crestline at a trumpet interchange. This unique interchange barely fits into this location on top of the mountain grade. This interchange marks the eastern terminus of California 138. From here, northbound California 18 changes directions to eastbound California 18 en route to Lake Arrowhead and Big Bear City. At Big Bear City, California 18 changes directions a second time, and starts to head north once again. Upon reaching Lucerne Valley, the highway changes directions once last time at its "bump" with California 247. California 18 heads west through Apple Valley and Victorville before terminating at its junction with ... California 138, the same road that is shown at this interchange near Crestline! Together with California 138, California 18 north/east of Crestline forms a loop tour through mountain and desert country. Photos taken 05/02/02.

From a vantage point along the old California 18 grade from Crestline south to San Bernardino, visitors can see a view of one of the most closely spaced interchanges in California. As noted earlier, California 18 and California 138 interchange is located south of Crestline. This is a trumpet interchange, which is clearly seen by the interchange configuration here. It may be the only kind of interchange that might work in such a close environment with tight turns and steep grades. Photos taken 04/18/04.
California 18 (outer) east
California 18 changes cardinal directions after the California 138 interchange. This view is found along eastbound California 18 at Lakeview Summit (Elevation 7,112 feet above sea level) just after the California 330 junction. California 18 is known as the "Rim of the World Highway" for a good reason! Photo taken 05/02/02.
Eastbound California 18 approaching Junction California 173. California 173 arcs north and then west from this point, passing along the east shore of private Lake Arrowhead and then west, via the only gravel road in the California state highway system, to the Mojave River Forks Regional Park and a back way to Deep Creek Hot Springs. California 173 ends at its junction with California 138 near Silverwood Lake. Photo taken 05/02/02.
This mileage sign provides the distances to Sky Forest, Running Springs, and Big Bear Lake after the California 173 junction along the Rim of the World Highway. Photo taken 04/18/04.
View of the next California 18 reassurance shield after the previous photobox, during a sunnier day. Photo taken 05/02/02.
After the Old Fire of October 2003 ravaged the mountain communities, several areas were badly burnt, including most of the area around Skyforest, as shown in these photos along eastbound. Photos taken 04/18/04.
This view is found along eastbound California 18 near Postmile 40. Photo taken 05/02/02.
In Running Springs, like most mountain communities of the San Bernardino Mountains, vehicles that interfere with snow plow operations may be ticketed and towed. This sign is located along eastbound as it approaches the intersection with California 330 south. Photo taken 04/18/04.
After passing through the community of Running Springs, California 18 east meets California 330 south. California 330 south follows the original route of California 30 southwest to Highland, where it ends at its junction with California 210/30. This sign is notable because it contains cardinal directions for both routes; neither California 18 nor California 330 are generally signed with cardinal direction indicators. Photo taken 04/18/04.
Eastbound California 18 approaches its intersection with California 38 at the west end of Big Bear Lake. California 18 remains on the south shore of Big Bear Lake, passing through the city of Big Bear Lake, while California 38 goes to the largely undeveloped north shore of Big Bear Lake. California 38 leads to a variety of hiking and other outdoor opportunities. California 18 and 38 converge in Big Bear City, which is located at the east end of the lake. Note that no cardinal direction indicators are located on these signs. Photo taken 05/02/02.
Eastbound California 18 meets California 38 at this point. Big Bear Lake comes into view in this picture. By following California 18 east along the south shore, motorists will cross over the dam that created this lake. At the time this picture was taken, the lake was low due to drought conditions that have remained for several years. Photo taken 05/02/02.
View of eastbound California 18 as seen from the dam area. Photo taken 05/02/02.
Eastbound/Northbound California 18 shield after the Big Bear Lake Dam and the western California 38 intersection. Photos taken 05/02/02.
Eastbound California 18 splits with Business California 18 in the City of Big Bear Lake. This shield assembly is a variation on the bypass/business sign seen on other state highways. The mainline California 18 turns left along Paine Road to avoid the downtown area. Photos taken 05/02/02.
California 18 (outer) north and California 38 north
California 18 and California 38 travel due north along their shared alignment in Big Bear City. Photo taken 05/02/02.
Northbound California 18 and California 38 approach their northerly split in Big Bear City. There are no cardinal directions here because both California 18 and California 38 have such irregular paths (both shaped like a backward letter "C"). Photo taken 05/02/02.
Use California 38 west (south) as an alternate route back to Los Angeles, as is California 18 north to Victorville via Lucerne Valley. Photo taken 05/02/02.
California 18 (outer) north
This mileage sign along northbound California 18 is posted after the split from California 38. The next three destinations are Lucerne Valley (Junction California 247), Apple Valley, and Victorville (Junction Interstate 15). Photo taken 04/18/04.
Baldwin Lake, a large dry lake bed situated just northeast of Big Bear Lake, is a natural lake that dried up many years ago. Today it is a large grassland with some barren areas that can flood during rain events. There is minimal development within the footprint of the lake. Photo taken 04/18/04.
The highway skirts the southern shore of the ancient lake, and the dry lake bed is clearly visible. Photo taken 04/18/04.
This California 18 reassurance marker is located along northbound as the highway skirts the northwestern shore of the dried-up lake. Photo taken 04/18/04.
Northbound California 18 at Baldwin Lake Road. Photo taken 04/18/04.
Now leaving the vicinity of Baldwin Lake, California 18 will ascend to a summit, then wind down toward the Mojave Desert. Photo taken 04/18/04.
California 18 reaches its highest altitude north of Big Bear City here, at this nondescript turnout. The turnout features a hiking trail that leads up to a nearby hill with a fantastic view of the desert below. The grade ahead is impressive, descending at 11%, which is almost double the allowable grade percentage for Interstate highways (which is generally 6 to 7% depending on waivers and exceptions for specific climbs). Photo taken 04/18/04.
Reaching its summit in the San Bernardino Mountains about midway between Big Bear City and Lucerne Valley, California 18 looks down into the desert from its perch. The highway takes a windy descent to reach the high desert below. Photo taken 04/18/04.
Upon reaching the base of the San Bernardino Mountains and exiting the San Bernardino National Forest, California 18 emerges in the high desert of Mojave. The two-lane highway passes by several limestone quarries, several of which are visible from great distances because they are located on the face of the mountains. In fact, the power lines on the west side of the highway primarily provide power to those limestone mining facilities. Photo taken 04/18/04.
As this signage shows, California 18 makes a left turn upon entering Lucerne Valley. This signage implies that California 18 actually meets California 247, but in reality, they do not meet. To get to California 247 north/south, motorists on California 18 must turn right onto this connector road. Note that both destinations for California 247 (Yucca Valley and Landers) are found along southbound. Landers was made famous in 1992 when an earthquake struck there, causing damage to some of the ubiquitous limestone quarries scattered about the region. Photos taken 04/18/04 and 06/27/09.
This photo looks north along the highway that links California 18 with California 247 as seen from the stop sign along northbound California 18. As promised, California 18 changes directions again, this time heading west toward Apple Valley and Victorville. Photo taken 04/18/04.
California 18 (outer) west
California 18 proceeds west through Lucerne Valley after the California 247 "bump" intersection. Due to the miles of open desert land ahead, California 18 motorists must use daytime headlights between Lucerne Valley and Apple Valley. Photo taken 06/27/09.
This California 18 west reassurance shield is posted near Rabbit Springs Dry Lake. Like California 247, California 18 passes over a dry lake that rarely sees any sort of standing water (except after significant rain events). Photo taken 06/27/09.
Rabbit Springs Dry Lake is easy to identify with its lack of vegetation and development. Photo taken 06/27/09.
California 18 passes under a branch of electrical transmission Path 46 (West of Colorado River), which includes these two 500kV power transmission lines owned by Southern California Edison. These lines link power generating stations located along the Colorado River with the Lugo substation in Hesperia southwest of here. These lines then proceed west, staying north of the San Gabriel Mountains, heading en route to the Vincent Substation near Palmdale. Photo taken 06/27/09.
The 500kV power transmission lines owned by Southern California Edison have a phase shift that utilizes these tall towers. Photo taken 06/27/09.
California 18 passes under another branch of electrical transmission Path 46 (West of Colorado River), which includes these two 220kV power transmission lines owned by Southern California Edison. Photos taken 06/27/09.
The daytime headlight requirement section ends along westbound California 18 as we crest at this slight rise. A beautiful sunset was in the making on this early summer's evening, mostly due to monsoonal moisture bringing clouds into the area. Photo taken 06/27/09.
Westbound California 18 meets Bear Valley Road at this cutoff. Turn left for Bear Valley Road west to Interstate 15 and Hesperia. Proceed northwest on California 18 to Apple Valley and Victorville. Photo taken 06/27/09.
No photos of this section of highway (from Bear Valley Road cutoff to California 138 via Victorville) are currently available. Stay tuned for updates!

California 18 INNER LOOP (Clockwise) from California 138 to California 210
California 18/Pearblossom Highway east
Leaving the intersection with California 138 near Llano in Los Angeles County, eastbound California 18 begins its 27-mile journey to Victorville on the northern slope of the San Gabriel Mountains and southern edge of the Mojave Desert. California 18 will proceed almost due east between the California 138 intersection and Interstate 15 interchange in Victorville, meeting U.S. 395 along the way. Photo taken 06/27/09.
Due to its location on the northern edge of the San Gabriel Mountains and wide washes that can bring floodwaters downhill from the mountains, California 18 can see the possibility of flash flooding, especially in summer with the possibility of heavy localized monsoonal thunderstorms. Photo taken 06/27/09.
Eastbound California 18 meets 263rd Street East. The daytime headlight safety requirement ends soon after this intersection. Photo taken 06/27/09.
The daytime headlight section comes to an end along California 18 east. Photo taken 06/27/09.

Eastbound California 18 leaves Los Angeles County and enters San Bernardino County. The state highway changes names from Pearblossom Highway to Palmdale Road at the county line. Photo taken 06/27/09.
California 18/Palmdale Road east
California 18/Palmdale Road continues east through an area subject to flooding. Photo taken 06/27/09.
Two Southern California Edison 500kV power lines cross over California 18/Palmdale Road. These lines connect the Vincent substation (near the California 14 and N-3/Angeles Forest Highway interchange) with the Lugo substation in Hesperia. Photos taken 06/27/09.
California 18/Palmdale Road continues east en route to Victorville. This section of the Mojave Desert is sparsely populated but does see some homesteads and ranches as the two-lane highway proceeds along its trek. Photos taken 06/27/09.
Eastbound California 18/Palmdale Road approaches Sheep Creek Road, which travels south to Phelan and ultimately connects to California 138. Turn left here for Sheep Creek Road north to El Mirage. Photos taken 06/27/09.
East of Johnson Road, California 18/Palmdale Road proceeds through the mostly undeveloped Mojave Desert. Joshua trees, a common plant found in the Mojave Desert, become more common as California 18 proceeds east and gradually loses elevation en route to Victorville. Photos taken 06/27/09.
Almost as if crossing a line, development emerges along California 18/Palmdale Road as we skirt the southern edge of the city of Adelanto (population 31,765 as of the 2010 Census and incorporated on December 22, 1970). Several intersecting roads link California 18 with the various residential developments, many of which are master planned and are subdivisions of ranches. A traffic signal governs the flow of traffic with Monte Vista Road, and some areas appear ripe for eventual development (such as the area around Bellflower Street). Nearing U.S. 395, we find a small shopping center that offers food, gas, and other goods and services. Photos taken 06/27/09.
In southern Adelanto near the commercial shopping area, eastbound California 18/Palmdale Road meets U.S. 395/Three Flags Highway at this traffic signal. U.S. 395 is a major north-south corridor that originates just south of here at Interstate 15 and extends north through the Mojave Desert into the Owens River Valley and the Eastern Sierra. Photo taken 06/27/09.
Turn right here for U.S. 395 south to Interstate 15 south en route to San Bernardino and San Diego. Turn left here for U.S. 395 north to downtown Adelanto, Ridgecrest, Independence, Bishop, and Reno. Ahead, California 18 will travel seven miles toward Victorville. Photo taken 06/27/09.
California 18 enjoys a four-lane segment east of U.S. 395. Photo taken 06/27/09.
East of U.S. 395, California 18 leaves Adelanto and enters the city of Victorville. The state highway passes by a power substation that has several power lines owned by Southern California Edison converging at this substation. The facility lines up on the south side of California 18. Photos taken 06/27/09.
Continuing east, California 18 proceeds through western Victorville and skirts the northern edge of the unincorporated Mountain View Acres residential development. Watch for increasing development as we proceed deeper into Victorville. The city of Victorville had a population of 115,903 as of the 2010 Census and is located in the Victor Valley (through which the Mojave River runs). The city incorporated on September 21, 1962, and it sits at an elevation of 2,726 feet above sea level. This series of pictures follows California 18 east as it meets Emerald Road, Diamond Road, and Cobalt Road (signalized intersection). Photos taken 06/27/09.
Eastbound California 18 meets Brucite Road and Amethyst Road, then passes under a pair of Los Angeles Department of Water and Power lines as well as a 500kV Southern California Edison/Los Angeles Department of Water and Power connector line that links a LADWP substation north of here with a Southern California Edison substation at Lugo near Hesperia. Photos taken 06/27/09.
Passing under those power lines, eastbound California 18 meets San Mateo Road and San Martin Road, then intersects Pacoima Road, Petaluma Road, and El Evado Road. El Evado Road is governed by a traffic signal. California 18 passes through a commercial zone with businesses on both sides of the state highway. Photos taken 06/27/09.
California 18 approaches Amargosa Road. Traffic increases as we get closer to the Interstate 15 corridor. Photo taken 06/27/09.
The next traffic signals along California 18 east are with Kentwood Boulevard and Park Avenue. Turn left to the Mojave Desert Air Quality Management offices as noted on this trailblazer sign. Photo taken 06/27/09.
Eastbound California 18 meets Interstate 15 almost immediately thereafter. The first right turn is the onramp to Interstate 15 south to San Bernardino, Los Angeles, and San Diego. Continue ahead for the second right onto Interstate 15 north and California 18 east to Lucerne Valley. Photo taken 06/27/09.
A high-speed ramp links California 18 east with Interstate 15 south. Photo taken 06/27/09.
California 18 east and Interstate 15 north will merge together. This allows California 18 to avoid most of Victorville, although it must pass through downtown to make its way east toward Apple Valley and Lucerne Valley. Photo taken 06/27/09.
The right lane of California 18 east connects to Interstate 15 north, which travels northeast along the former U.S. 91 corridor toward Barstow, Las Vegas, and St. George. Photo taken 06/27/09.
Eastbound California 18 departs from Palmdale Boulevard onto Interstate 15 north (right exit). The left two lanes of Palmdale Bouelvard continue ahead into downtown Victorville and becomes designated as Business Loop I-15 and Historic U.S. 66-91. Photo taken 06/27/09.
The freeway entrance shield assembly includes both California 18 and Interstate 15. Photo taken 06/27/09.

Business California 18-30/Highland Avenue (San Bernardino) east
After the California 259 interchange, a Business California 18 reassurance shield is posted on eastbound Highland Avenue in San Bernardino. Omitted is a reassurance shield for Business California 30. The designation of this section as Business California 18 is due to the prior designation of California 259 as part of California 18. Prior to 1964, California 18 was defined to follow the Riverside Freeway corridor (Interstate 215 south and California 91 west) toward Orange County. That state route was truncated to its current interchange with California 210, but the business route has remained signed as far south as the California 259 and Highland Avenue interchange. Photo taken 07/15/07.
This view provides another view of the same shield assembly from 2002 along eastbound Highland Avenue (former California 18/30) in San Bernardino. As noted above, this is also technically Business California 30, but there aren't any shields for it here. Photos taken 05/02/02.

At this traffic signal, eastbound Business California 18-30/Highland Avenue meets Former California 206 (Former Business U.S. 66)/H Street. This north-south corridor travels north to Kendall Drive and eventually Interstate 215 along the path of Former Business U.S. 66 (California 206 was the designation of the route after the U.S. designation was removed but before the state transferred maintenance to the city). To the south, H Street leads into downtown San Bernardino. Photo taken 07/15/07.
Next up is the traffic signal with D Street. Photo taken 07/15/07.
The next traffic signal along eastbound Highland Avenue is with Arrowhead Avenue. Photo taken 07/15/07.

Business California 18/Sierra Way (San Bernardino) south
Business California 18-30/Highland Avenue west
Traveling west on Highland Avenue, Business California 18 will end at the interchange with California 259. Business California 30/Highland Avenue continues west to California 210 Exit 28. California 259 is the connector freeway between Interstate 215 northbound and California 210 eastbound. There is one exit from this short connector freeway, and that interchange is with Highland Avenue. This business route is signed along Highland Avenue between the California 259 interchange and Sierra Way. The business route was left behind when California 18 was truncated to its current southern terminus at California 210. At one time, California 18 used to continue southwest via California 259 and California 91 to Long Beach. This old sign does not have any button copy on it, but it is from the 1960s. Photos taken 07/15/07 and 05/02/02.
The next right connects Business California 18-30 with California 259 north to California 210 east. The next left connects to California 259 south to Interstate 215 south and both directions of Interstate 10. Interstate 10 is signed for Los Angeles because this interchange is nearly the spot where the San Bernardino Freeway begins its westerly journey toward downtown Los Angeles. Photos taken 07/15/07 and 05/02/02.
This freeway entrance shield is one of two that straddle the onramp to California 259 north to California 210 west. This sign was likely replaced with California 210 shields. Photo taken 07/15/07.
