The economic effects of the occupation were positive for Reykjavík: the unemployment of the Depression years vanished, and construction work began. The British built Reykjavík Airport, which remains in service today, mostly for short haul flights (to domestic destinations and Greenland). The Americans, meanwhile, built Keflavík Airport, situated  west of Reykjavík, which became Iceland's primary international airport. In 1944, the Republic of Iceland was founded and a president, elected by the people, replaced the king; the office of the president was placed in Reykjavík.
