In Alabama, Interstate 20 travels 214.7 miles through the center of the state. It enters the state from Mississippi near Cuba, and travels northeastward through Tuscaloosa and Birmingham. At Birmingham, I-20 turns eastward and heads through Oxford before crossing the Georgia state line near Lebanon. Other cities on the route include Livingston, Bessemer, and Pell City.
For more than half its 130-mile (210 km) distance, I-20 overlaps Interstate 59 from the Mississippi border to eastern Birmingham near Birmingham International Airport. Mileage and exits on the concurrency are I-59's, although both routes have the same mileage for the Alabama duplex.
After Interstate 20/59 enters Alabama from Mississippi, they travel concurrently northeastward across the Tombigbee River and Black Warrior River delta country which is generally low-lying farmland until reaching Tuscaloosa. This area contains low population. US Highway 11 parallels this route from Mississippi northeastward while it passes through small towns like York, Livingston, and Eutaw before reaching Tuscaloosa.
