Oresund Bridge (2000)
A 7.8 km combined road-and-rail link between Copenhagen and Malmo opened in July 2000. Trains cross in about 35 minutes and run every 20 minutes.
It merged two cities into a single labor market, the Oresund Region.
Rail carries most cross-link travelers, making it the leading example of cross-sea rail commuting.
It is the clearest precedent for what Ningbo wants: a cross-sea rail link that turns a separate county into a functional suburb.
