Pålsundsbron

Pålsundsbron is a bridge in central Stockholm, Sweden. Stretching over the small water course Pålsundet, the bridge connects the major island Södermalm to the minor island Långholmen.

The name Pålsundet, on old maps called Påhl Sundet, or Pålsund, refers to the poles blocking the canal from ships trying to reach central Stockholm without paying the required duty. Also, an iron chain served the same purpose of forcing the ships pay a visit to the custom house demolished during the 1930s. The bridge was known as Mälarvarvsbron or more locally Varvsbron until 1948 when it received its present name.The original bridge on this location, after Långholmsbron the second bridge stretching over Pålsundet, was built in 1907 as a wooden truss bridge.
