The Swedish Transport Administration (Swedish: Trafikverket) is a government agency in Sweden. It is responsible for long-term infrastructure planning for all kinds of transport: road, rail, shipping and aviation. It owns, constructs, operates and maintains all state-owned roads and railways and operates a large number of ferry services.
A special committee oversaw the effectivity of the Swedish transport agencies during 2008 and 2009. A conclusion was reached that there would be significant gains compared with the then-present situation if a new agency responsible for long-term planning of the transport system for road, rail, maritime and air traffic was formed. Preparations started in the autumn of 2009, and the new authority began its work on 1 April 2010.
