Siøsund Bridge

The Siøsund Bridge (Siøsundbroen) is a road bridge that connects the Danish islands of Tåsinge and Siø. It crosses Siøsund, a shallow strait that allowed much of the link to be built as a causeway, the Siø Causeway or Siø Dam (Siødæmningen).

The bridge is a low box girder bridge that does not allow the passage of ships. It consists of 20 identical spans, each 27 m long, and was the first bridge in Denmark to be built from prefabricated concrete box girders. The road deck is 7.0 m wide, with a 2.5 m pavement on either side.

The bridge and causeway are part of route 9 which also connects Tåsinge to Funen via the Svendborgsund Bridge and Siø to Langeland via the Langeland Bridge.
