The Old Gotham Freeway is a stretch of road that encompassed Park Row and Amusement Mile. When Arkham City was constructed, the freeway was incorporated into it. After Protocol 10, part of the road was destroyed.
Arkham City Incident
More of the freeway was destroyed by the Penguin to prevent the Joker from sending his henchmen into Penguin's territory. Vicki Vale was stranded and targeted by snipers on that freeway when her helicopter was shot down by the Joker.
After Arkham City Incident
The Freeway was reconstructed after the events of Arkham City was closed down.
