U.S. Route 66 or U.S. Highway 66 was one of the original highways in the United States Numbered Highway System. It was established on November 11, 1926, with road signs erected the following year. The highway, which became one of the most famous roads in the United States, ran from Chicago, Illinois, through Missouri, Kansas, Oklahoma, Texas, New Mexico, and Arizona before terminating in Santa Monica in Los Angeles County, California, covering a total of 2,448 miles (3,940 km).
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 Mojave River is an intermittent river in the eastern San Bernardino Mountains and the Mojave Desert in San Bernardino County, California, United States.

State Route 91 (SR 91) is a major east–west state highway in the U.S. state of California that serves several regions of the Greater Los Angeles urban area. A freeway throughout its entire length, it officially runs from Vermont Avenue in Gardena, just west of the junction with the Harbor Freeway, east to Riverside at the junction with the Pomona and Moreno Valley freeways.
U.S. Route 91 or U.S. Highway 91 is a 172.7-mile-long (277.9 km) north–south United States highway running from Brigham City, Utah, to Idaho Falls, Idaho, in the U.S. states of Idaho and Utah. Despite the "1" as the last digit in the number, US 91 is no longer a cross-country artery, as it has mostly been replaced by Interstate 15. The highway currently serves to connect the communities of the Cache Valley to I-15 and beyond. Prior to the mid-1970s, US 91 was an international commerce route from Long Beach, California, to the Canada–US border north of Sweetgrass, Montana. US 91 was routed on the main streets of most of the communities it served, including Las Vegas Boulevard in Las Vegas and State Street in Salt Lake City. From Los Angeles to Salt Lake, the route was built along the corridor of the Arrowhead Trail. A portion of the highway's former route in California is currently State Route 91.

They are marked by the state flower, a California poppy, inside either a rectangle for state-maintained highways or a pentagon for county highways.
The Southern California freeways are a vast network of interconnected freeways in the megaregion of Southern California, serving a population of 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.
State Route 18 is a state highway in the U.S. state of California. It serves as a primary route into the San Bernardino Mountains, both from the Riverside–San Bernardino metropolitan area from the south and the Mojave Desert from the north. SR 18 runs from State Route 210 in San Bernardino to State Route 138 in Llano. It has two discontinuities: one in Big Bear Lake, the other in Victorville.
National Old Trails Road, also known as the Ocean-to-Ocean Highway, was established in 1912, and became part of the National Auto Trail system in the United States. It was 3,096 miles (4,983 km) long and stretched from Baltimore, Maryland to California. Much of the route follows the old National Road and the Santa Fe Trail. Following its decommission, the western portion was later integrated into U.S. Route 66.
Las Vegas Boulevard is a major road in Clark County, Nevada, United States, best known for the Las Vegas Strip portion of the road and its casinos.

Old Las Vegas Mormon Fort State Historic Park is a state park of Nevada. It contains the Old Mormon Fort, the first permanent structure built in what would become Las Vegas fifty years later. In present-day Las Vegas, the site is at the southeast corner of Las Vegas Boulevard and Washington Avenue, less than one mile north of the downtown area and Fremont Street. This is the only U.S. state park located in a city that houses the first building ever built in that city. The fort was listed on the National Register of Historic Places on February 1, 1972. The site is memorialized with a tablet erected by the Church of Jesus Christ of Latter-day Saints in 1997, along with Nevada Historical Marker #35, and two markers placed by the Daughters of Utah Pioneers.

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.
Interstate 15 (I-15) is an Interstate Highway, running from San Diego, California, United States, to the Canada–US border, through Mohave County in northwest Arizona. Despite being isolated from the rest of Arizona, in the remote Arizona Strip, and short in length at 29.43 miles (47.36 km), it remains notable for its scenic passage through the Virgin River Gorge. The highway heads in a northeasterly direction from the Nevada border northeast of Mesquite, Nevada, to the Utah border southwest of St. George, Utah.
Interstate 15 (I-15) is an Interstate Highway in the U.S. state of Nevada that begins in Primm, continues through Las Vegas and it crosses the border with Arizona in Mesquite. Within the state, the freeway runs entirely in Clark County. The highway was built along the corridor of the older U.S. Route 91 (US 91) and Arrowhead Trail, eventually replacing both of these roads.
Pikes Peak Ocean to Ocean Highway was an early coast-to-coast highway in the United States. The route crossed the nation from New York City to Los Angeles, and was in direct competition with the Lincoln Highway and the National Old Trails Road. Its route markers were marked PP-OO.
Mormon Road, also known to the 49ers as the Southern Route, of the California Trail in the Western United States, was a seasonal wagon road pioneered by a Mormon party from Salt Lake City, Utah led by Jefferson Hunt, that followed the route of Spanish explorers and the Old Spanish Trail across southwestern Utah, northwestern Arizona, southern Nevada and the Mojave Desert of California to Los Angeles in 1847. From 1855, it became a military and commercial wagon route between California and Utah, called the Los Angeles – Salt Lake Road. In later decades this route was variously called the "Old Mormon Road", the "Old Southern Road", or the "Immigrant Road" in California. In Utah, Arizona and Nevada it was known as the "California Road".
