The St. Lucie County Florida map places Fort Pierce’s lagoon-and-inlet waterfront beside the much larger planned city of Port St. Lucie. The Indian River Lagoon and Hutchinson Island line the east, while I-95, Florida’s Turnpike, agricultural land, and wetlands organize the interior.

What the Map Shows
Fort Pierce occupies the east-central lagoon shore around Fort Pierce Inlet. St. Lucie Village follows the lagoon north of the city, Lakewood Park reaches the far northern mainland, and Port St. Lucie spreads across the southern half of the county.
Within Port St. Lucie, St. Lucie West lies near I-95 and Tradition extends farther west along Tradition Parkway. River Park sits along the North Fork north of central Port St. Lucie, while White City lies between Port St. Lucie and Fort Pierce.
County Layout and Location
Indian River County borders St. Lucie County to the north, Okeechobee County to the west, Martin County to the south, and the Atlantic Ocean to the east. Hutchinson Island forms the coastal barrier, the Indian River Lagoon separates it from the mainland, and Fort Pierce Inlet provides the ocean opening.
US 1 follows the mainland’s north-south urban corridor, while SR A1A serves the barrier island. I-95 and Florida’s Turnpike carry longer-distance traffic through the interior; the two limited-access routes cross near SR 70 west of Fort Pierce.
SR 70, also known locally as Okeechobee Road, links Fort Pierce with the western county. SR 68 follows Orange Avenue, Midway Road crosses the county between Fort Pierce and Port St. Lucie, and Gatlin Boulevard–Tradition Parkway connects eastern Port St. Lucie with I-95 and Tradition.
Local Context
The county has three incorporated municipalities with distinct map roles. Fort Pierce is the county seat and inlet city; Port St. Lucie is the expansive southern population center; and the Village of St. Lucie Village is a small municipality on the lagoon north of Fort Pierce.
Tradition is not a separate city. It is part of Port St. Lucie’s later west-of-I-95 growth, along with Southern Grove and other planned areas. St. Lucie West is another planned Port St. Lucie district and sits closer to the interstate and the North Fork.
Water geography explains much of the county’s shape. The Indian River Lagoon supports an estuarine shoreline east of US 1, the North Fork St. Lucie River reaches into Port St. Lucie, and the Savannas preserve a long freshwater-marsh corridor behind the Atlantic coastal ridge.

- Orient neighboring-county travel toward Indian River, Okeechobee, or Martin County.
Frequently Asked Questions
Why does Port St. Lucie occupy so much more of the map than Fort Pierce?
Port St. Lucie began as a large planned city and later incorporated major areas west of I-95. Its 2020 Census land area was 119.22 square miles, so its municipal boundary covers far more ground than the older, compact city of Fort Pierce.
Is Tradition a separate city or part of Port St. Lucie?
Tradition is part of the City of Port St. Lucie, not a separate municipality. It lies west of I-95 along Gatlin Boulevard and Tradition Parkway and represents part of the city’s newer western planned development.
