Vehicle Jammed Highway

The jammed/congested highway is the starting point and main location in Season 2 of The Walking Dead (TV Series). It is first seen in the episode, What Lies Ahead and has played a role since Sophia disappeared.

What Lies Ahead
Since the survivors left Atlanta, they used this stretch of highway to try and get to Fort Benning however, they come to a stop when they find the highway blocked with several abandon vehicles; as well to make matters worse, Dale's camper RV breaks down due to his radiator hose yet again stranding them on the highway for quite some time.

While scavenging the vehicles for supplies, a herd of walkers passes by on the highway. Rick Grimes tells everyone to hide underneath the cars until the group of undead passed however, Sophia gets the unwanted attention of two walkers. She runs off the highway towards the woods nearby to avoid the walkers that are pursuing her, however, she is not seen since the incident.

Bloodletting
While part of the group goes out to look for Sophia, Dale and T-Dog stay behind to fix the RV and await Sophia's return. Since T-Dog cut his arm badly on a wrecked car when hiding from The Herd, Dale goes and scavenges some cars in effort to look for antibiotics for him. Once the other group encounters Maggie in the woods, Glenn heads back to the highway and takes T-Dog to Hershel's Farm where a few continued to stay behind and await Sophia's return.



Save the Last One
Daryl couldn't sleep due to hearing Carol cry. He decides to go and continue to look for Sophia at night and Andrea goes with him. Not being able to find her, Daryl and Andrea emerge near the highway and head back to Dale's RV.

Cherokee Rose
The group decide to leave the highway and join the rest at Hershel's Farm since the search for Sophia seems to be less and less likely to find her or her returning to the highway however, they leave a message for her and some food and water in case she does return. Shane even though was injured and had a hard time walking, he volunteered to drive up and down the highway in an effort to find Sophia.



Chupacabra
Though the survivors have left the highway, the highway was used during the evacuation of Atlanta since the military began its bombardment on the city.
