Svinesund is a sound separating the Swedish municipality of Strömstad in the province of Bohuslän in the county of Västra Götaland from the Norwegian municipality of Halden in the county of Østfold. Two bridges, the old and new Svinesund Bridge, span this sound of the Iddefjord. The Swedish side is extremely popular with Norwegians who flock to buy relatively cheap goods in Sweden, where a large shopping area can be found immediately after crossing the sound. Following the inauguration of the new bridge in June 2005, both the old and new bridges are toll bridges.
