The Siøsund Bridge (Danish: 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 (Danish: Siødæmningen).

It consists of 20 identical spans, each 27 metres (89 ft) long,[2] and was the first bridge in Denmark to be built from prefabricated concrete box girders.

[2] 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.
