According to The Öresund Committee, the bridge has made a national economic gain of DKK 57 billion, or SEK 78 billion SEK (~€8.41 billion) on both sides of the strait by increased commuting and lower commuting expense. The gain is estimated to be SEK 6.5 billion per year but this could be increased to 7.7 billion by removing the three biggest obstacles to integration and mobility, the two largest being that non-EU nationals in Sweden are not allowed to work in Denmark and that many professional qualifications and merits are not mutually recognised.
