Danviksbro

Story

Danviksbron or, alternatively, Danviksbro is a bascule bridge in central Stockholm, Sweden, connecting the eastern end of Södermalm to the eastern municipality Nacka. Under the bridge, the canal Hammarbykanalen carries the water of Hammarby Sjö over to Saltsjön. The bridge, actually two separate bridges, carries the railway Saltsjöbanan and a road.For unknown reasons the location of the bridge, like many other places along the shores of Sweden and Norway, was named 'Danviken', meaning danernas vik, "The Bay of the Danes", and until the early 20th century most people called it Dannviken rather than, as is common today, Daanviken .HistorySince King Gustav Vasa (1496–1560) had the water level of the lake Hammarbysjön increased by 4.8 metres, the lake emptied into Saltsjön through a small rivulet overshadowed by a simple wooden bridge and the familiar silhouette of an old mill, and for many centuries Danviken remained mostly renowned for its hospital, Danviks hospital, which the king had moved from Riddarholmen near the city.In 1922, a railway viaduct built in 1893 was demolished together with the old bridge, both replaced by a single-leaf bascule bridge with its concrete counterweight hanging over the 14 metres wide roadway shared by trains and vehicles. On the eastern side of the canal a concrete viaduct connected to the bridge, and the bridge's load-carrying steel trusses left a horizontal clearance of 12.5 metres for the ships below.
