Question: is there a tunnel between denmark and sweden

Answer: Yes, The Øresund or Öresund Bridge (Danish: Øresundsbroen (ˈøːɐsɔnsˌbʁoːˀn̩); Swedish: Öresundsbron (œːrɛ2sɵnːdsˌbruːn); hybrid name: Øresundsbron) is a combined railway and motorway bridge across the Øresund strait between Sweden and Denmark. The bridge runs nearly 8 kilometres (5 miles) from the Swedish coast to the artificial island Peberholm in the middle of the strait. The crossing is completed by the 4-kilometre (2.5 mi) Drogden Tunnel from Peberholm to the Danish island of Amager.
