The Vaidya radiating metric is used to model an evaporating black hole space-time. The black hole is outlined along with the properties of the different space-time regions. The global structure of the space-time manifold arising from the model is examined, and similarities and differences from the canonical picture are noted. It is shown that a physical connection between the two asymptotically flat regions, classically separated, is possible, and that a wormhole is produced in analogy with the Einstein-Rosen bridge. The validity of these conclusions for a more general evaporating space-time is discussed, and their physical consequences are assessed.
