St. Johns County, Florida in the context of "Julington Creek"

St. Augustine (/ˈɔːɡəstiːn/ AW-gə-steen; Spanish: San Agustín [san aɣusˈtin]) is a city in and the county seat of St. Johns County, Florida, United States. Located 40 miles (64 km) south of downtown Jacksonville, the city is on the Atlantic coast of northeastern Florida. Founded in 1565 by Spanish settlers, it is the oldest continuously inhabited European-established settlement in what is now the contiguous United States.

St. Augustine was founded on September 8, 1565, by Spanish admiral Pedro Menéndez de Avilés, Florida's first governor. He named the settlement San Agustín, because his ships bearing settlers, troops, and supplies from Spain had first sighted land in Florida eleven days earlier on August 28, the feast day of St. Augustine. The city served as the capital of Spanish Florida for over 200 years. It became the capital of British East Florida in 1763 and continued as the capital after the 1783 Treaty of Versailles in the Second Spanish Period.

There are 67 counties in the U.S. state of Florida, which became a territory of the U.S. in 1821 with two counties complementing the provincial divisions retained as a Spanish territory, Escambia to the west and St. Johns to the east. The two counties were divided by the Suwannee River. All of the other counties were created later from these two original counties. Florida became the 27th U.S. state in 1845, and its last county was created in 1925 with the formation of Gilchrist County from a segment of Alachua County. Florida's counties are subdivisions of the state government. Florida's most populous county is Miami-Dade County, the seventh most populous county in the nation, with a population of 2,701,767 as of the 2020 census.

In 1968, counties gained the power to develop their own charters. All but two of Florida's county seats are incorporated municipalities: the exceptions are Crawfordville, county seat of rural Wakulla County, and East Naples, located outside Naples city limits in Collier County.

The Jacksonville Beaches, or Jax Beaches known locally as "The Beaches", are a group of towns and communities on the northern half of San Pablo Island on the US state of Florida's First Coast. These communities are separated from the main body of the city of Jacksonville by the Intracoastal Waterway. The Jacksonville Beaches are located in Duval and northern St. Johns counties, and make up part of the Jacksonville metropolitan area. The main communities generally identified as part of the Beaches are Mayport, Atlantic Beach, Neptune Beach, Jacksonville Beach, and Ponte Vedra Beach.

Dixie Highway was a United States auto trail first planned in 1914 to connect the Midwest with the South. It was part of a system and was expanded from an earlier Miami to Montreal highway. The final system is better understood as a network of connected paved roads, rather than one single highway. It was constructed and expanded from 1915 to 1929.

The Dixie Highway was inspired by the example of the slightly earlier Lincoln Highway, the first road across the United States. The prime booster of both projects was promoter and businessman Carl G. Fisher. It was overseen by the Dixie Highway Association and funded by a group of individuals, businesses, local governments, and states. In the early years, the U.S. federal government played little role, but from the early 1920s on it provided increasing funding until 1927. That year the Dixie Highway Association was disbanded and the highway was taken over by the federal government as part of the U.S. Route system, with some portions becoming state roads.
