Interstate 15 (I-15) is a major Interstate Highway in the Western United States, running through Southern California and the Intermountain West. I-15 begins near the Mexican border in San Diego County and stretches north to Alberta, Canada, passing through the states of California, Nevada, Arizona, Utah, Idaho, and Montana. The Interstate serves the cities of San Diego, San Bernardino, Las Vegas, Salt Lake City, Idaho Falls, and Great Falls. It also passes close to the urban areas of Los Angeles, Orange, and Riverside counties, California. The stretches of I-15 in Idaho, Utah, and Arizona have been designated as the "Veterans Memorial Highway". The southern end is at a junction with I-8 and State Route 15 (SR 15) in San Diego, and the northern end is at a connection with Alberta Highway 4 at the Sweetgrass–Coutts Border Crossing.
The Los Angeles County Metropolitan Transportation Authority (LACMTA), branded as Metro, is the county agency that plans, operates, and coordinates funding for most of the public transportation system in Los Angeles County, California, the most populated county in the United States.
The Capitol Corridor is a 168-mile (270 km) passenger train route in Northern California operated by Amtrak between San Jose, in the Bay Area, and Auburn, in the Sacramento Valley. The route is named after the two points most trains operate between, San Jose and Sacramento. The route runs roughly parallel to I-880 and I-80. Some limited trips run between Oakland and San Jose. A single daily round trip runs between San Jose and Auburn, in the foothills of the Sierra Nevada. Capitol Corridor trains started in 1991.
The San Joaquins is a passenger train service operated by Amtrak in California's San Joaquin Valley. Seven daily round trips run between its southern terminus at Bakersfield and Stockton, with onward service to Sacramento and Oakland. For Fiscal year 2025, two additional trips to Sacramento will be added.
State Route 138 is an east–west state highway in the U.S. state of California that generally follows the northern foothills of the San Gabriel Mountains and the western Mojave Desert. The scenic highway begins in the west at its junction with Interstate 5 located south of Gorman in the Sierra Pelona Mountains, continues eastward through the Antelope Valley and Cajon Pass, to its junction with State Route 18 in the east, located in the San Bernardino Mountains south of Crestline.
California High-Speed Rail (CAHSR) is a publicly funded high-speed rail system being developed in California by the California High-Speed Rail Authority. Phase 1, about 494 miles (795 km) long, is planned to run from San Francisco to Los Angeles and Anaheim via the Central Valley, and is partially funded and under construction. A proposed Phase 2 would extend the system north to Sacramento and south to San Diego, for a total of 776 miles (1,249 km). The project was authorized by a 2008 statewide ballot to connect the state's major urban areas and reduce intercity travel times. Phase 1 targets a nonstop travel time of 2 hours and 40 minutes from San Francisco to Los Angeles, compared to about nine hours on the existing Amtrak San Joaquins.
A vast network of interconnected freeways in the megaregion of Southern California serves a population of over 23 million people. The Master Plan of Metropolitan Los Angeles Freeways was adopted by the Regional Planning Commission in 1947 and construction began in the early 1950s. The plan hit opposition and funding limitations in the 1970s, and by 2004, only some 61% of the original planned network had been completed.
Amtrak California is a brand name used by the California Department of Transportation (Caltrans) Division of Rail for three state-supported Amtrak regional rail routes in California – the Capitol Corridor, the Pacific Surfliner, and the San Joaquins – and their associated connecting network of Amtrak Thruway transportation services.
The Victor Valley is a valley in the Mojave Desert and subregion of the Inland Empire, in San Bernardino County in Southern California.
The California–Nevada Interstate Maglev project was a proposed 269 mi (433 km) Maglev train line from Las Vegas, Nevada, to Anaheim, California. One segment would run from Las Vegas to Primm, Nevada, with proposed service to the Las Vegas area's forthcoming Ivanpah Valley Airport. The top speed would be 310 mph (500 km/h). Though $45 million was appropriated in 2005 for the planning phase for the first 40 mi (64 km) segment, the money was never spent, and was finally reallocated to a highway project in a Las Vegas Airport in June 2010. The maglev project was not in the 2012 transportation plan under consideration by the Southern California Association of Governments. Removing it from the plan means that the project cannot receive federal funds, even for studies. The Southern California Association of Governments did leave a small portion of the route – from Anaheim to Ontario – in their 2012 transportation plan.
Route 15, consisting of the contiguous segments of State Route 15 (SR 15) and Interstate 15 (I-15), is a major north–south state highway and Interstate Highway in the U.S. state of California, connecting San Bernardino, Riverside, and San Diego Counties. The route consists of the southernmost 289.24 miles (465.49 km) of I-15, which extends north through Nevada, Arizona, Utah, Idaho, and Montana to the Canada–US border. It is a major thoroughfare for traffic between San Diego and the Inland Empire, as well as between Southern California, Las Vegas, Nevada, and the Intermountain West.
The Palmdale Transportation Center is a multi-modal transportation center in the city of Palmdale, California.

Brightline West is a privately run high-speed rail route, currently under construction, to link the Las Vegas Valley and Rancho Cucamonga in Greater Los Angeles through the California high desert. The line will connect with existing rail at Rancho Cucamonga station of Metrolink's San Bernardino Line, a commuter rail line in Southern California. The project is intended to provide an alternative to air and automobile travel between Southern California and Las Vegas, a popular leisure destination. In December 2023, the United States Department of Transportation awarded Brightline West a $3 billion grant as part of the Infrastructure Investment and Jobs Act. Construction, initially expected to begin shortly after the grant was announced in 2023, began on April 22, 2024. Revenue service is planned to start in 2028.

The California High-Speed Rail system will be built in two major phases. Phase I, about 520 miles (840 km) long using high-speed rail through the Central Valley, will connect San Francisco to Los Angeles. In Phase 2, the route will be extended in the Central Valley north to Sacramento, and from east through the Inland Empire and then south to San Diego. The total system length will be about 800 miles (1,300 km) long. Phase 2 currently has no timeline for completion.
The San Bernardino County Transportation Authority (SBCTA) is the successor to San Bernardino Associated Governments (SANBAG). They are responsible for administering the Measure I half-cent tax which voters in San Bernardino County, California, passed most recently in 2004. The SBCTA conducts transportation planning, construction, and operation in San Bernardino County. The SBCTA is a joint powers authority comprising the entire county and its cities. Every city and county supervisor is provided one seat on the board, and it also includes a nonvoting member from the California Department of Transportation's (Caltrans) District 8.
The Portal, also known as the Downtown Rail Extension (DTX), is a planned second phase of the Salesforce Transit Center. When complete, it will extend the Caltrain Peninsula Corridor commuter rail line from its current northern terminus at 4th and King via a 1.3-mile (2.1 km) tunnel. The new terminus will be near the Financial District and will provide intermodal connections to BART, Muni, Transbay AC Transit buses, and long-distance buses. In addition, the California High Speed Rail Authority (CHSRA) plans to use DTX and the Caltrain-owned Peninsula Corridor for service on the CHSRA San Francisco–San Jose segment. The Caltrain Modernization Program (CalMod), which included electrification of the line and acquisition of electrified rolling stock, was a prerequisite, since the former diesel locomotives were not suitable for use in a tunnel.
Victor Valley is a future high-speed rail station of Brightline West, running to Las Vegas Boulevard in the Las Vegas Valley and south to Rancho Cucamonga.
