Ideas for a fixed link across the Øresund were advanced as early as the first decade of the 20th century. In 1910, proposals were put to the Swedish Parliament for a railway tunnel across the strait, which would have comprised two tunnelled sections linked by a surface road across the island of Saltholm. The concept of a bridge over the Øresund was first formally proposed in 1936 by a consortium of engineering firms who proposed a national motorway network for Denmark.
