As early as 1990, Trondheim in Norway had introduced a pay road from the city center to the airport. Shortly after, in 1991, a cordon was introduced around the city center. After some years a growing opinion was developing saying this cordon was unfair, because a lot of residents living and working either outside or inside the cordon did not have to pay. Therefore, in 1996 a system with 6 (later 7) cordons was introduced, splitting the city into so many zones, that a much large number of car drivers had to pay. With 7 cordons Trondheim was the city in the world with most cordons. Charging was abandoned by the 31. December 2005.
