I think some consider the Fehmarn Belt Fixed Link to consist of multiple parts, as the main tunnel (Fehmarn Belt Tunnel proper) is between a German island and a Danish island so stops a bit short. On the Danish side, they rebuild the Storstrøm Bridge, and on the German side they decided to build another tunnel alongside the existing Fehmarn Sound Bridge. So in total, one existing bridge, one rebuilt bridge, one short new tunnel and one long new tunnel will connect Germany proper to Denmark proper.
