Swedish Transport Administration

The Swedish Transport Administration () is a government agency in Sweden, controlled by the Riksdag and the Government of Sweden. It is responsible for long-term infrastructure planning for transport: road, rail, shipping and aviation. It owns, constructs, operates and maintains all state-owned roads and railways and operates many car ferry services.

The agency is a member of the Nordic Road Association. For shipping and aviation, it only does planning and purchasing unprofitable traffic. Trafikverket does not do practical physical work to construct or maintain roads or railways, because that is done by separate companies which Trafikverket write contracts with and pay.
