How has this exemption been arrived at?

The basic purpose of the current structure and design of the congestion tax levied in the Backa area is to avoid through-traffic. This purpose has been achieved, but has also resulted in crossings into and out of the area that is taxed. The stations have proved as barriers for those people who live and work in Backa, since they have to pay congestion tax if, for example, they want to go shopping, leave their children at day care centres, etc. Following an extensive dialogue with local residents and business people in the area, and a local decision-making process, the parties in the West of Sweden Package decided that the negative effects on Eastern Hisingen are unacceptable.
