- Merge to I-65 and then I-10 West through the Gulf region
- Continue west across Texas to San Antonio
- Often slightly longer in distance and time
Drivers in north metro Atlanta (Alpharetta, Roswell, Sandy Springs) may prefer using the Perimeter (I-285) to connect with I-20 West. Those in south metro (College Park, East Point, Forest Park) may find it easier to connect to I-85 or I-20 more quickly.
