Centralbron in the context of "Söderström (Stockholm)"

Norrström is one of the shortest rivers in Europe in central Stockholm. It connects Lake Mälaren with the Baltic Sea. It runs from Riddarfjärden, north of Gamla stan, to Stockholms ström (the western part of Saltsjön). Two islands lie within it, Strömsborg and Helgeandsholmen. It is one of two natural waterways between Mälaren and the Baltic sea, the other being Söderström south of Gamla stan. Norrström is crossed by Centralbron and the adjacent pedestrian bridge, Vasabron, Riksbron north of Helgeandsholmen which continues into Riksgatan and Stallbron south of the island, Norrbro crossing Helgeandsholmen, and Strömbron.

While the majority of the river flows north of Helgeandsholmen, a small controlled portion known as the Stallkanalen (sv) runs south of the island, between it and Gamla stan.

Gamla stan is a station on the Green and Red lines of the Stockholm metro. It is located on the western side of the Gamla Stan (Old town) district of central Stockholm, and is at ground level, although partly under the Centralbron bridge that carries road and mainline rail across the waterways that define the centre of the city. The same waterways are responsible for the ground level location of the station, unusual for a city centre metro station, as the lines cross between the islands of Stadsholmen and Södermalm by a bridge immediately south of the station.

The station has two island platforms between four parallel through tracks, with the western platform for trains to the north and the eastern one for trains to the south. Red line trains use the inner pair of tracks and Green line the outer tracks. The platforms are accessed from a ticket hall located under the tracks and platforms. The ticket hall can be reached from Mälartorget, Munkbroleden or Munkbrohamnen.
