Cau Cau Bridge

What was supposed to be the first drawbridge in South America ended up as a monument to inefficiency and made laughingstocks of those involved when, just before construction finished, it was discovered that one of the bridge’s two spans had been installed upside down. The $42 million project was later featured in the Discovery Channel documentary “Horrors of Calculation” as an engineering mistake too expensive to fix. The bridge, which spans the Cau Cau River in the lovely city of Valdivia, is unusable except as a background for selfies and a caution to anyone whose mind wanders during calculus class.
