The Bridge (Left 4 Dead 2)

The Table Bridge is the fifth and final chapter of the campaign called The Parish. After the survivors have escaped from the ruins of New Orleans, they learn that the U.S. army is abandoning the mainland, trying to hold out at sea on large cruise ships the survivors take this chance, and make a run for it. This chapter is believed to be named "The Table Bridge".

Walkthrough
The Survivors start out in a small safe room, apparently constructed out of a maintenance room for the bridge, which exits into the northern point of the bridge. The route back to the city has been blocked, and there is a corpse with a radio propped up against the concrete barricade. This sends the army a message to hold out until the Survivors get to the docking point on the other side of the bridge.

The Survivors then have to navigate the stalled out buses and trucks that line the bridge, and also sections of the overhanging deck that has collapsed, until they finally reach the end, where they are rescued and the game ends.
