U.S. Route 99 (US 99) was a main north–south United States Numbered Highway on the West Coast of the United States until 1964, running from Calexico, California, on the US–Mexico border to Blaine, Washington, on the U.S.-Canada border. It was assigned in 1926 and existed until it was replaced for the most part by Interstate 5. Known also as the "Golden State Highway" and "The Main Street of California", US 99 was important throughout much of the 1930s as a route for Dust Bowl immigrant farm workers to traverse the state. Large portions are now California's State Route 99 (SR 99), Oregon Route 99, 99W, 99E and Washington's SR 99. The highway in Washington connected to British Columbia Highway 99 at the Canada–US border, which is also named for US 99.

The Algodones Dunes is a large sand dune field, or erg, located in the southeastern portion of the U.S. state of California, near the border with Arizona and the Mexican state of Baja California. The field is approximately 45 miles (72 km) long by 6 miles (9.7 km) wide and extends along a northwest-southeast line that correlates to the prevailing northerly and westerly wind directions. The name "Algodones Dunes" refers to the entire geographic feature, while the administrative designation for that portion managed by the Bureau of Land Management is the Imperial Sand Dunes Recreation Area. In 1966, Imperial Sand Hills was designated as a National Natural Landmark by the National Park Service. The Algodones Dunes are split into many different sections. These sections include Glamis, Gordon's Well, Buttercup, Midway, and Patton's Valley. Although the Arabic-derived Spanish word algodones translates to "cotton plants", the origin of the toponym is unknown.

The Butterfield Overland Mail in California was created by the United States Congress on March 3, 1857, and operated until June 30, 1861. Subsequently, other stage lines operated along the route until the Southern Pacific Railroad arrived in Yuma, Arizona in 1877.
Southern Emigrant Trail, also known as the Gila Trail, the Kearny Trail, Southern Trail and the Butterfield Stage Trail, was a major land route for immigration into California from the eastern United States that followed the Santa Fe Trail to New Mexico during the California Gold Rush. Unlike the more northern routes, pioneer wagons could travel year round, mountain passes not being blocked by snows, however it had the disadvantage of summer heat and lack of water in the desert regions through which it passed in New Mexico Territory and the Colorado Desert of California. Subsequently, it was a route of travel and commerce between the eastern United States and California. Many herds of cattle and sheep were driven along this route and it was followed by the San Antonio-San Diego Mail Line in 1857-1858 and then the Butterfield Overland Mail from 1858 - 1861.
The Otay Mesa Port of Entry is one of three ports of entry (POE) in the San Diego–Tijuana metropolitan region, in the U.S. state of California, connecting Otay Mesa in the City of San Diego with the Otay Centenario borough of Tijuana. The facility was opened in 1983, and was constructed primarily to divert growing commercial truck traffic from the busy San Ysidro Port of Entry. Since then, significant passenger vehicle and pedestrian traffic has grown as development in the area around the crossing has grown. Commercial importations through Otay Mesa accounts for billions of dollars' worth of freight.
The Calexico West Port of Entry is one of two ports of entry in the Imperial Valley area of California. It is located in the business center of the Calexico-Mexicali metropolitan area that is divided by an international boundary. This crossing has easy access north to Interstate 8 via California State Route 111. Mexican Federal Highway 5 then begins its journey to the south. The General Services Administration is currently implementing a multi-year facility upgrade that will dramatically change the appearance and throughput of the border crossing.
