 Some legends have elements of related folktale categories, for example Deceiving the Devil (AT #1196), The Devil's Contract (AT #756B), and The Master Builder legends.One version of the tale presents the bridge builder and the Devil as adversaries.This reflects the fact that frequently, such as in the case of the "Teufelsbrücke" at the St Gotthard Pass, these bridges were built under such challenging conditions that successful completion of the bridge required a heroic effort on the part of the builders and the community, ensuring its legendary status.
