teufelsbrücken or a bridge too far

The ever fascinating Atlas Obscura presents a collection of unholy spans, which medieval superstitions credited to master civic planner and engineer, the Devil himself, over the seemingly impossible feats of architecture that ancient crossings imparted to people seeing them for the first time.
Featuring amazing old stone bridges from all over Europe, the article talks about the folklore that grew up around them, with common stories of townspeople striking a deal with Satan to construct a much needed but beyond human-abilities and gravity-defying bridge over rivers and ravines. The Devil agreed to give the mortals their bridge but usually in exchange for the soul of the first to cross it. The Devil was inevitably denied his due because either an over-excited dog ran across first or the villagers sent over a stubborn goat. How they outwitted Satan is preserved in local legend and sometimes commemorated with sculpture and artwork. At one of the hair-pin curves going into a tunnel along the shores of Lugano in Switzerland, there was a relief of the Devil coming out of the cliff-face—I wonder if there was some similar tale about connecting the region overland as well as by sea.
