Johanneshovsbron (Swedish: "The Johanneshov Bridge") is a 756 metres long and 17,9 metres wide road bridge in central Stockholm, Sweden. Overpassing two older bridges, Skansbron and Skanstullsbron, and one newer bridge, Fredriksdalsbron, it connects Södermalm and the tunnel passing under it, Söderledstunneln, to Johanneshov, the district immediately south of the historical city centre, and national road 73, leading out of the city.
Swedish is a North Germanic language spoken natively by 10 million people, predominantly in Sweden, and in parts of Finland, where it has equal legal standing with Finnish. It is largely mutually intelligible with Norwegian and to some extent with Danish, although the degree of mutual intelligibility is largely dependent on the dialect and accent of the speaker. Both Norwegian and Danish are generally easier for Swedish speakers to read than to listen to because of difference in accent and tone when speaking. Swedish is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Era. It has the most speakers of the North Germanic languages.
A bridge is a structure built to span a physical obstacle, such as a body of water, valley, or road, without closing the way underneath. It is constructed for the purpose of providing passage over the obstacle, usually something that can be detrimental to cross otherwise. There are many different designs that each serve a particular purpose and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it.
Stockholm is the capital of Sweden and the most populous urban area in the Nordic countries; 962,154 people live in the municipality, approximately 1.5 million in the urban area, and 2.3 million in the metropolitan area. The city stretches across fourteen islands where Lake Mälaren flows into the Baltic Sea. Just outside the city and along the coast is the island chain of the Stockholm archipelago. The area has been settled since the Stone Age, in the 6th millennium BC, and was founded as a city in 1252 by Swedish statesman Birger Jarl. It is also the capital of Stockholm County.
Brought about by the construction of the tunnel, Johanneshovsbron forms part of one of the major roads passing through the central city, extending north over Centralbron. Running south form the mouth of Söderledstunneln to the west of Skanstull, the bridge runs uphill and somewhat in parallel to Skanstullsbron for some 500 metres before it turns east to pass over its neighbour, between which ramps it finally extends into road 37 underneath the roundabout at Johanneshov.

Centralbron is one of the major traffic routes in central Stockholm, Sweden, connecting the northern district Norrmalm to the southern Södermalm.
Skanstull is an area in Södermalm in Stockholm. Skanstull connects the traffic between the inner city and the south parts of Stockholm and its suburbs. Skanstull was originally the city’s southern toll station, but the toll station was removed in 1857.
The bridge is made of prestressed concrete, has an average span of 51 metres (max 55,7 metres), and was inaugurated on 9 October 1984. [1]
Prestressed concrete is a form of concrete used in construction that while under construction is substantially "prestressed" (compressed) in the areas that will be subjected to tensile forces while in service to strengthen it against these forces.
