The Bridge is the third chapter of the fifth campaign, Blood Harvest. The Survivors exit the railroad tunnel and re-enter the forest. They follow a pathway through a gully up to a service building connected to an extension of the railroad tunnel. By entering this building and descending a flight of stairs, the Survivors are able to re-join the tracks in the open air once again. After defeating the Infected hordes, the Survivors climb the fallen bridge to reach high ground. They briefly head back into the forest before entering a small cabin serving as the ending safe room.
