Lauderdale County Alabama map | County Boundary and Places

The Lauderdale County Alabama map is easiest to read with Florence as the southern urban anchor, Killen and Rogersville along the eastern U.S. 72 corridor, Anderson and Lexington near the Tennessee border, and Waterloo in the western Tennessee River landscape. The county’s southern edge is inseparable from Wilson Dam and the broader Shoals area across the river in Colbert County.

Quick Facts

The U.S. Census Bureau estimates 97,135 residents as of July 1, 2025, 3.8 percent above the 2020 estimates base of 93,566. The 2020 census counted 93,564 residents. Lauderdale is therefore one of the larger counties in northwest Alabama, with much of that population concentrated in and around Florence.

The county covers 668.01 square miles of land and had a 2020 density of 140.1 people per square mile. Urban development is strongest around Florence, while the Tennessee-border north and Mississippi-facing west remain much more rural.

What the Map Shows

Florence is the county seat and the dominant administrative, educational, medical, and commercial center. It sits on higher ground above the north bank of the Tennessee River and connects by bridge to Sheffield, Muscle Shoals, and Tuscumbia in Colbert County. The river divides counties but not the regional labor and service market.

Killen and Rogersville form the most obvious eastern corridor. U.S. 72 ties both communities to Florence and continues toward Limestone County and the Huntsville area. Killen is closer to the Florence suburban edge, while Rogersville acts as a separate service center farther east.

Anderson and Lexington represent the northern Tennessee-border countryside. Their road network is more agricultural and dispersed, and some regional orientation runs north toward Tennessee communities as well as south toward Florence.

Waterloo occupies the far western river country near Mississippi. Its location along the Tennessee River and the Pickwick side of the waterway gives it a very different setting from the eastern U.S. 72 towns.

St. Florian and Underwood-Petersville help define the transition north of Florence. St. Florian is a small incorporated town, while Underwood-Petersville marks the more continuous residential and commercial edge between the city and the rural north.

The eight labeled places are Anderson, Florence, Killen, Lexington, Rogersville, St. Florian, Underwood-Petersville, and Waterloo. Grouping them into the Florence urban core, eastern highway corridor, northern border country, and western river country gives the map a stronger spatial logic.

County Layout and Location

Lauderdale County occupies Alabama’s northwestern corner. Tennessee lies to the north, Mississippi touches the west, Limestone County lies to the east, and Lawrence and Colbert counties are to the south. The Tennessee River shapes much of the southern edge and links the county to the rest of the Shoals region.

U.S. 43 is the main north-south route through Florence. It crosses the Tennessee River toward Muscle Shoals and Tuscumbia and continues north toward Tennessee, making it one of the strongest links between both sides of the river.

U.S. 72 is the principal east-west corridor. From Florence it runs through Killen and Rogersville toward Athens and Huntsville, while westbound connections lead toward Mississippi. It is the clearest highway framework for the eastern half of the county.

Alabama 20 is important on the western side, while Alabama 101, 133, and 157 connect rural communities to Florence and the U.S. Highway network. With no Interstate directly crossing Lauderdale County, these U.S. and state routes carry most regional travel.

ALDOT lists an April 2005 countywide functional-classification map for Lauderdale County but an April 2025 Shoals MPO map for the urbanized area. The newer MPO sheet is the better reference for current road hierarchy around Florence and the cross-river metro.

The Tennessee River also acts as a transportation filter. The City of Florence notes that the river forms portions of its eastern and southern boundaries, so bridge locations and the Wilson Dam area concentrate movement between Florence and Colbert County.

Local Context

Florence was laid out in 1818 for the Cypress Land Company. Italian surveyor Ferdinand Sannoner designed the town and selected the name Florence, while the site itself occupied high ground overlooking the Tennessee River—an advantageous position for commerce and settlement.

City historical markers identify Florence as the Lauderdale County seat and record its first incorporation in 1826. The city’s early economy developed at the foot of the Muscle Shoals, linking agriculture, river trade, manufacturing, and later rail transportation.

Wilson Dam spans the Tennessee River between Florence and Muscle Shoals. TVA states that construction ran from 1918 to 1925, the dam is 4,541 feet long, and it remains TVA’s largest conventional hydroelectric facility. Its reservoir covers about 15,500 acres.

The dam transformed the map of the Shoals. Stable navigation, power generation, and industrial development strengthened the two sides of the river as one economic region. For Lauderdale County, Wilson Dam is therefore infrastructure that explains metropolitan geography, not merely a landmark.

Lauderdale County is one of six counties in the Muscle Shoals National Heritage Area. The heritage area focuses on three regional themes—music, Native American heritage, and the Tennessee River—across Colbert, Franklin, Lauderdale, Lawrence, Limestone, and Morgan counties.

The area’s music identity also crosses the river. Famous studios associated with the Muscle Shoals sound are largely in Colbert County, while Florence contributes its own musical institutions and history, including W. C. Handy’s legacy. The map is therefore more accurate when Florence is seen as part of a cross-county cultural region.

The western county also intersects the historic Natchez Trace corridor. National Park Service records place an Old Natchez Trace resource about 15 miles northwest of Florence near Alabama 20, showing that the Waterloo and Mississippi-facing side followed important travel routes long before modern highways.

Smaller waterways shaped settlement as well. Muscle Shoals National Heritage Area research notes that Cypress Creek, Shoal Creek, Bluewater, and other streams supported nineteenth-century gristmills, sawmills, textile mills, and other water-powered industries across Lauderdale County.

Ways to Use This Map

Start with Florence and mark the Tennessee River along the southern edge. Add U.S. 43 as the north-south line and U.S. 72 as the east-west line. That immediately establishes the Florence–Shoals connection and the Killen–Rogersville corridor.

Next separate Anderson and Lexington from the U.S. 72 towns. They belong more naturally to the Tennessee-border rural zone, where local roads and cross-state connections matter more than the Florence suburban pattern.

Finally, treat Waterloo as a distinct western river zone. It shares the Tennessee River system with Florence, but its Mississippi-facing rural setting and proximity to the Pickwick side of the waterway give it a different travel and settlement pattern.

• Use Florence and U.S. 43/U.S. 72 as the county’s administrative and transportation center.
• Group Killen and Rogersville along the eastern U.S. 72 corridor toward Huntsville.
• Read Anderson and Lexington as Tennessee-border rural communities.
• Use Waterloo to orient the western river and Mississippi-facing side.
• Treat Wilson Dam and the Tennessee River as the infrastructure axis linking Florence with the wider Shoals metro.

FAQ

Are Florence and Muscle Shoals in the same county?

No. Florence is in Lauderdale County, while Muscle Shoals, Sheffield, and Tuscumbia are mainly across the Tennessee River in Colbert County. Bridges, Wilson Dam, shared employment, shopping, and cultural institutions nevertheless make the two sides function as the wider Shoals metropolitan area.

Why is the Tennessee River so important on a Lauderdale County map?

The river shapes much of the southern county edge and explains Florence’s site, bridge locations, Wilson Dam, industrial development, and the cross-river Shoals economy. It also connects very different landscapes: the dense Florence side in the southeast and the quieter Waterloo river country farther west.
