Interstate 3

Interstate 3 (I-3) is a planned 104-mile-long (167 km) Interstate highway running from Interstate 16 near Pembroke, Georgia to Interstate 20 in North Augusta, South Carolina. Once complete, the freeway will connect Savannah to Augusta in Georgia. Interstate 3 has been named as the Alliance of Independent Nations Expressway, since it is the first mainline interstate to begin construction since Carolina entered into the Alliance in 2016. GDOT and SCDOT plan to award a contract by July 2018 with construction beginning in late 2018. The expected completion date is late 2022.

SCDOT has conducted environmental studies and preliminary planning to extend I-3 north to Greenville. The alignment would parallel CS 25 and CS 221 and would have a northern terminus at either I-385 or I-26 near Clinton.
