Centralbron

Since the first decade of the 20th century, numerous proposals labelled "Centralbron" had been produced and more than 20 of them scrapped before the elaboration of the general plan of 1928.

While the metro system and Centralbron were being constructed Slingerbultsleden had to be scrapped, and in 1953 it was substituted by a 240-metre-long (790 ft) pontoon bridge connecting the northern end of the now non-existent Riddarholmskajen ("Quay of Riddarholmen") to Klara strand.

[1] WW2 further delayed any attempts to elaborate a permanent solution, but in 1947 a decision to build a southern bridge crossing Söderström was taken, and work finally begun in 1950.

The continuous steel girders of the roadway are resting on concrete pillars firmly anchored to the soil by numerous poles.

To the north, the bridge is continuous with a 173-metre-long (568 ft) viaduct passing over the Gamla stan metro station, opened 1957.

Over the years, Centralbron together with a suggested additional railway track have been much criticized and debated because of their unwieldy and rumbling presence in a delicate historical setting.
