Through mid-morning, vehicles had backed up Berckmanns Road to Walton Way, and jammed Ingleside Drive and Wheeler Road.
The free parking lots were filling up, but officials said some spots should remain available throughout the day.
Earlier this morning a stalled bus briefly slowed traffic. Officials said they think the bus was bringing children to an Augsuta event when it broke down on the westbound Interstate-20 exit ramp to Washington Road.
It was moved off the roadway, and another bus was sent to pick up the children.
I-20 traffic was later complicated when an oversized truck carrying concrete materials moved slowly through the Augusta interchange.
