In a way Copenhagen has done a similar thing. The harbour used to be a terrible mess in 1995 with sewage and whatnot going in but these days the water is so clean that swimming in the harbour became a thing. Last year the Diesel harbour busses were replaced by electric ships and the seafront is a place where tons of locals hang out and enjoy the city in summer.

Maybe, just maybe, we'll be able to uncover Ladegårds Å and get rid of the terrible concrete street mess that is Åboulevard.
