Lee County Florida map | Fort Myers, Cape Coral, and Sanibel

Lee County Florida map — Read the county as a network of river crossings, inland highway corridors, and island gateways: Fort Myers and Cape Coral flank the Caloosahatchee, Lehigh Acres spreads eastward, and Pine Island, Sanibel, and Fort Myers Beach occupy separate coastal approaches.

What the Map Shows

Fort Myers, the county seat, stands on the south bank of the Caloosahatchee River. Cape Coral occupies the broad area north and west across the water, while North Fort Myers lies directly opposite downtown. The river and municipal boundaries distinguish these similarly named places.

Lehigh Acres fills a large inland grid east of Fort Myers, connected by SR 82 and Lee Boulevard. South of the central city, the airport, Gateway, Estero, and Bonita Springs form a separate growth corridor organized around I-75 and U.S. 41.

The Gulf side is not a single shoreline. Pine Island and Matlacha Pass, the Sanibel-Captiva barrier island, Estero Island at Fort Myers Beach, and mangrove islands within Estero Bay create multiple channels and shallow bays between the mainland and open Gulf waters.

County Layout and Location

Lee County occupies Southwest Florida between Charlotte County to the north, Glades to the northeast, Hendry to the east, Collier to the south, and the Gulf of Mexico to the west. The Caloosahatchee enters from the eastern boundary, crosses the urban core, and reaches San Carlos Bay north of Sanibel.

I-75 runs north-south inland from the coast and supplies the regional connection toward Charlotte and Collier counties. U.S. 41 passes through North Fort Myers and Fort Myers, then continues through South Fort Myers, Estero, and Bonita Springs as a more urban commercial corridor.

SR 80 follows the Caloosahatchee eastward from central Fort Myers, while SR 82 angles southeast through Lehigh Acres toward inland Collier County. SR 78 crosses North Fort Myers and northern Cape Coral before reaching Matlacha and Pine Island; SR 31 forms another north-south route in the county’s northeastern sector.

Water crossings control local movement. The Cape Coral Bridge and Midpoint Memorial Bridge connect Cape Coral with the Fort Myers side of the river. Sanibel Causeway reaches Sanibel from Punta Rassa, and Pine Island Road crosses Matlacha Pass on the only road approach to Pine Island.

Local Context

The Caloosahatchee estuary extends from the W. P. Franklin Lock downstream to Shell Point and San Carlos Bay. Freshwater inflow affects salinity and water quality throughout this transition zone, so the river functions both as an urban divide and as the ecological link between inland drainage and the Gulf.

Estero Bay became Florida’s first aquatic preserve in 1966. Seagrass beds, mangroves, oyster reefs, and shallow channels occupy the space between mainland development and the barrier islands, making the county’s coastal geography as important as its road network.

Cape Coral’s extensive canal system produces a street pattern unlike Fort Myers’ riverfront core. Lehigh Acres has another distinctive form: a vast inland grid with dispersed residential development. Farther south, Estero and Bonita Springs align more closely with the I-75 and U.S. 41 corridors.

Southwest Florida International Airport sits southeast of Fort Myers in unincorporated Lee County, roughly three miles east of I-75. Daniels Parkway, Treeline Avenue, and Terminal Access Road define its approach, which is separate from the downtown street network.

The county grew from 760,822 people in the 2020 Census to an estimated 875,607 in 2025, a 15.1 percent increase from the 2020 estimates base. Growth is distributed among Cape Coral, Lehigh Acres, and the southern I-75 corridor rather than concentrated only in Fort Myers.

Ways to Use This Map

Separate Fort Myers, North Fort Myers, and Cape Coral by riverbank and bridge
Compare the I-75 and U.S. 41 north-south corridors
Trace SR 78, SR 80, and SR 82 toward Pine Island, the eastern river corridor, and Lehigh Acres
Identify the limited mainland approaches to Sanibel, Captiva, Fort Myers Beach, and Pine Island
Place the airport correctly southeast of Fort Myers and east of I-75

For island trips, begin with the gateway bridge rather than straight-line distance. Sanibel, Fort Myers Beach, and Pine Island rely on different access corridors, and a closure or heavy congestion at one crossing can determine the entire route.

This is a general geographic reference, not an emergency or navigation product. Evacuation zones, flood hazards, road closures, beach access, and boat-ramp conditions change over time; verify those details through Lee County’s address lookup and the responsible local agency before travel.

Frequently Asked Questions

Which bridges connect Fort Myers and Cape Coral?

The Cape Coral Bridge on the southern approach and the Midpoint Memorial Bridge near the center provide the direct connections. Routes farther north cross through North Fort Myers, so the best crossing depends on the origin and destination within each city.

Do Pine Island and Sanibel share the same road access?

No. Pine Island is reached on SR 78 and Pine Island Road through Matlacha. Sanibel is reached from Punta Rassa on Sanibel Causeway. The islands appear close on a regional view, but their mainland approaches are entirely separate.

Is Lehigh Acres part of the City of Fort Myers?

No. Lehigh Acres is a large unincorporated community east of Fort Myers, not an incorporated city or a Fort Myers neighborhood. SR 82 and Lee Boulevard link the two areas, but their boundaries and development patterns remain distinct.
