Fig. 1 - S2 (02.01.2019) - The Sound bridge-tunnel connects the road & rail networks of Sweden & Denmark across the 15km wide strait.
Oresund Strait formed only ~8000 years ago as a result of rising sea levels after the ice age, it connected the North Sea to a large fresh water lake.

Construction began in 1995, with the bridge opening to traffic on 1 July 2000. The tunnel was built to avoid interfering with air traffic from Copenhagen Kastrup Airport, to provide a clear channel for tall ships no matter the weather, and to prevent ice floes from blocking the strait by aggregating along the bridge piers
Fig. 5 - S1 (18.03.2018) - It now allows around 19 millions passager crossings yearly, of which two-thirds by train.
The 4km long artificial island Peberholm in the middle of the strait connects the brige to the tunnel. It was built to protect the biodiversity of Saltholm island located just north from the nuisance caused by the traffic.
