Upon leaving Augusta, I-20 crosses the Savannah River and enters the Palmetto State and heads northeastward, bypassing Aiken and Lexington before reaching the state capitol of Columbia, which can be reached most directly by taking I-26 east at Exit 63 ("Malfunction Junction"), then, almost immediately, I-126/US-76.
At Columbia, Interstate 20 bypasses the city to the north and again turns northeastward, bypassing Fort Jackson and Camden. After crossing the Wateree River, it turns due east, passes by tiny Bishopville, before reaching the Florence area. It is near Florence where I-20 sees its eastern terminus at Interstate 95. However, for about two miles, the highway continues into Florence as Business Spur 20.
I-20 in the Palmetto State is known as either the J. Strom Thurmond Freeway or John C. West Freeway. The first section to be completed was the bridge over the Savannah River around 1964, the last, the section between US 401 and I-95 (including the Business Spur), opened in 1974.
