It's an effort to ease congestion on the busy tollroad.
The shoulder will only be open weekday mornings from 6:30 to 9:30 a.m.
The Georgia Department of Transportation expects it to take a while for drivers to get used to the new traffic pattern. GDOT plans to see how things go with until next fall.
