Mount Badon Bridge is the last bridge the player has to cross in Act l to get to the Parade. The bridge is guarded by Downer Detectors at the main entrance and a Bobby on the other side, whose purpose is to check if Wellies have a Letter of Transit to cross.
- The name is a reference to the Battle of Badon, which occurred during the late 5th or early 6th Century between the Celtic Britons and Anglo-Saxons.
- Due to the plague outbreak in the Parade (the events of Act l involving Arthur Hastings), the bridge is closed off to be quarantined before Ollie Starkey can cross the bridge in Act lll.
- Sally Boyle never crosses Mount Badon Bridge during Act ll gameplay, as the bobby is Out for Tea when she visits the bridge.
- The Memory, Trains, can be found on the other side of the bridge.
