Interstate 5 in California in the context of "California State Route 14"

Orange County (officially the County of Orange; often initialized O.C.) is a county located in the Greater Los Angeles area in Southern California, United States. As of the 2020 United States census, the population was 3,186,989, making it the third most populous county in California, the sixth most populous in the United States, and more populous than 19 U.S. states and Washington, D.C. Although mostly suburban, it is the second most densely populated county in the state behind San Francisco County. The county's three most populous cities are Anaheim, Santa Ana and Irvine, each of which has a population surpassing 300,000. Santa Ana is also the county seat. Six cities in Orange County lie along the Pacific Coast: Seal Beach, Huntington Beach, Newport Beach, Laguna Beach, Dana Point and San Clemente.

Orange County is included in the Los Angeles–Long Beach–Anaheim Metropolitan Statistical Area. The county has 34 incorporated cities. Older cities such as Tustin, Santa Ana, Anaheim, Orange and Fullerton have traditional downtowns dating back to the 19th century, while newer commercial development or "edge cities" stretch along the Interstate 5 (Santa Ana) Freeway between Disneyland and Santa Ana and between South Coast Plaza and the Irvine Business Complex and cluster at Irvine Spectrum.

Woodland is a city in and the county seat of Yolo County, California, United States. Located approximately 15 miles (24 km) northwest of Sacramento, it is a part of the Sacramento metropolitan area. The population continues to grow every year, with a growth rate of 0.33% annually, and a current population of 61,873.

Woodland's origins date to 1850 when California gained statehood and Yolo County was established. The area was well irrigated due to the efforts of James Moore, which drew people into farming as the soil was very fertile. The city gained a federal post office in 1861 with the help of Missourian Frank S. Freeman. A year after this, in 1862, the county seat was moved from Washington (present day West Sacramento) to Woodland after Washington was flooded. The addition of a railroad line to Sacramento, and the more recent addition of Interstate 5, helped the city to thrive.

Irvine Spectrum is a district in southeastern Irvine, Orange County, California, centered on the Irvine Spectrum Center shopping and lifestyle center. It is also an edge city, a concentration of business, shopping, and entertainment outside a traditional downtown, as defined by Joel Garreau in his 1991 book Edge City: Life on the New Frontier.

The Irvine Spectrum Center is anchored by Target, Nordstrom and a large Edwards Cinema multiplex. Office space is leased by the Irvine Company, which promotes Irvine Spectrum as Orange County's new tech hub and its new "Downtown" of office space, with 13 million square feet of office space in over 40 office "communities". The area also includes apartments, and is immediately adjacent to two other districts that by Garreau's abovementioned criteria would make them part of the edge city:

U.S. Route 101 (US 101) is a major north–south United States Numbered Highway, stretching from Los Angeles, California, to Tumwater, Washington. The California portion of US 101 is one of the last remaining and longest U.S. Routes still active in the state, and the longest highway of any kind in California. US 101 was also one of the original national routes established in 1926. Significant portions of US 101 between the Los Angeles area and the San Francisco Bay Area follow El Camino Real, the commemorative route connecting the former Alta California's 21 missions.

Although the highway has been superseded in overall importance for transportation through the state by Interstate 5 (I-5), US 101 continues to be the major coastal north–south route that links the Greater Los Angeles Area, the Central Coast, the San Francisco Bay Area, and the North Coast (Redwood Empire). Generally referred to as "101" by residents of Northern California, in Southern California it is often called "The 101" (pronounced "the one oh one"). The highway has portions designated as the Santa Ana Freeway, the Hollywood Freeway, the Ventura Freeway, South Valley Freeway, and Bayshore Freeway, as well as El Camino Real in many non-freeway segments. The Redwood Highway, the 350-mile-long (560 km) northernmost segment of the highway, begins at the Golden Gate and passes through the world's tallest and only extensive preserves of virgin, old-growth coast redwood trees.

State Route 1 (SR 1) is a major north–south state highway that runs along most of the Pacific coastline of the U.S. state of California. At 656 miles (1,056 km), it is the longest state route in California, and the second-longest in the US after Montana Highway 200. SR 1 has several portions designated as either Pacific Coast Highway (PCH), Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 (I-5) near Dana Point in Orange County and its northern terminus is at U.S. Route 101 (US 101) near Leggett in Mendocino County. SR 1 also at times runs concurrently with US 101, most notably through a 54-mile (87 km) stretch in Ventura and Santa Barbara counties, and across the Golden Gate Bridge.

The highway is designated as an All-American Road. In addition to providing a scenic route to numerous attractions along the coast, the route also serves as a major thoroughfare in the Greater Los Angeles Area, the San Francisco Bay Area, and several other coastal urban areas. Though some maps and signs mark SR 1 as continuous through the cities of Dana Point, Newport Beach, Santa Monica, and Oxnard, control of segments within those cities were relinquished to those local jurisdictions and are thus no longer officially part of the state highway system. The Golden Gate Bridge is also officially not included in the state highway system because it is maintained locally by the Golden Gate Bridge, Highway and Transportation District.

State Route 89 (SR 89) is a state highway in the U.S. state of California that travels in the north–south direction, serving as a major thoroughfare for many mountain communities in the Sierra Nevada and the Cascade Range. It starts from U.S. Route 395 near Topaz Lake, winding its way up to the 8,314-foot (2,534 m) Monitor Pass, down to the Carson River, and up again over the 7,740-foot (2,359 m) Luther Pass. From that point on, the route generally loses elevation on its way past Lake Tahoe, through Tahoe and Plumas National Forests until Lake Almanor. For roughly 9 miles (14 km) the route forms a concurrency with State Route 36. SR 89 then ascends to the 5,753-foot (1,754 m) Morgan Summit. After it enters Lassen Volcanic National Park it continues to gain elevation until it reaches its highest point through an unnamed pass in the middle of Lassen Peak and Bumpass Mountain. While SR 89 is signed as a continuous route through the park, the portion inside Lassen Volcanic National Park is federally maintained and is not included in the state route logs. The road then descends out of the park and heads northwest, finally terminating at Interstate 5 at the foot of Mount Shasta at around 3,600 feet (1,100 m).

El Camino Real (Spanish; literally The Royal Road, sometimes translated as The King's Highway) is a 600-mile (965-kilometer) commemorative route connecting the 21 Spanish missions in California (formerly the region Alta California in the Spanish Empire) from Mission San Diego de Alcalá in San Diego to Mission San Francisco Solano in Sonoma, along with a number of sub-missions, four presidios, and three pueblos. The route is historically associated with a network of royal roads (caminos reales) used by inhabitants of New Spain. The modern commemorative route in the U.S. state of California is named after these roads, and is officially defined in the California Streets and Highways Code to run along various roads from Interstate 5 at the Mexican border to State Route 12 in Sonoma.

During the period of Spanish rule, there was no single road constructed by the Spanish to connect the missions, with most of the network of royal roads following historic Native American trading routes. These various caminos reales covered much of what is today California, but with no single special route designated to link the missions. The name was revived in the American era in connection with the boosterism associated with the Mission Revival movement of the early 20th century. Streets throughout California bear the "El Camino Real" name. The route has been continually upgraded and is decorated with commemorative bell markers.

Tracy is the second most populated city in San Joaquin County, California, United States. The population was 93,000 at the 2020 census and estimated at 100,136 in 2024. Tracy is located inside a geographic triangle formed by Interstate 205 on the north side of the city, Interstate 5 to the east, and Interstate 580 to the southwest.
