Decaying Riverside Bridge (and Collapsed Rubble)

The decaying bridge spans the riverside in a desolate future London, its structure weakened by years of neglect amid the city's eerie silence. Susan climbs a nearby wall, loses her footing, twists her ankle, and triggers its collapse. Rubble from the bridge crashes down, piling over the TARDIS and burying it completely, stranding the Doctor, Ian, Barbara, and Susan. The Doctor and Ian assess the massive debris pile, recognizing their isolation from the ship and forcing them to seek tools elsewhere.
