Between Texas and South Carolina, I‑20 runs through northern Louisiana, central Mississippi, western and north-central Alabama, and north-central Georgia. I‑20 intersects seven of the ten primary north–south Interstates (all except I‑5, I‑15, and I‑25) and also the east-west Interstates 10 and 30.

From its terminus at I‑95, the highway continues about 2 miles (3.2 km) eastward into the city of Florence as Business Spur 20.

I-20 begins 10 miles (16 km) east of Kent at a fork with I-10. From there, the highway travels east-northeastward through Odessa, Midland, and Abilene before turning eastward towards Dallas/Fort Worth. The La Entrada al Pacifico corridor runs along I-20 between U.S. Route 385 (US 385) and Farm to Market Road 1788 (FM 1788). Between Monahans and I-10, I-20 has an 80 miles per hour (130 km/h) speed limit.
