Stocksundet


Stocksundet is a strait in Stockholm County in Sweden. It connects the Edsviken sea inlet, to the west, with the Lilla Värtan strait and eventually the Baltic sea, to the east. The strait also forms the border between the suburb of Stocksund in Danderyd Municipality, to the north, and the suburb of Bergshamra in Solna Municipality, to the south. The strait is approximately long and varies in width between and, whilst its depth varies between and.
Stocksundet is supposed to have received its name from the logs which used to be laid out in the water to stop invading ships in the early Middle Ages. This name then led to the place name of Stocksund, on the north side of the sound, and to the heraldry shield of the then Stocksund Municipality between 1955 and 1966.
By the 1400s, the road between Roslagen and Stockholm crossed Stocksundet, and by the 17th century, a ferry was provided. In 1716 the first bridge across the Stocksundet was built, principally to facilitate the movement of troops to the west in the event of an attack by Russia. Since then, there have been a total of seven bridges built across the strait.

Bridges

From west to east, the strait is spanned by a bridge for the Stockholm metro, a road bridge for the European route E18, and a bridge for the Roslagsbanan narrow gauge commuter railway. Over time there have been seven bridges across the Stocksundet:
