The first proposal for a bridge connecting Kungsholmen with Långholmen was made in 1903 when plans to relocate the main northern railway passing through Stockholm to the west of the central city were discussed. The proposal mainly focused on a railway bridge however and, as the traffic in Stockholm at the time hardly could motivate a bridge of such dimensions, proposing a road-rail bridge was probably meant to emphasize the technical feasibility of such a bridge. The project was included in a proposal in 1905 but was not mentioned again before the 1920s.
