Europe’s Mightiest Bridge, Connecting Denmark and Sweden

Part of the fun of traveling in Europe is using massive and inspiring infrastructure — like this bridge that connects Denmark and Sweden. In this clip, my train is in an erector set-type tunnel under an-eight lane highway crossing the Øresund Bridge. Behind me is Copenhagen (not Stockholm, as I say), and up ahead is Malmö, Sweden.
