The story
The agency was founded in 1841 as the Royal Board for Public Road and Water Structures (Swedish: Kongliga styrelsen för allmänna wäg- och wattenbyggnader) and was responsible for Sweden's canals and roads. In 1967, the agency changed its name to the National Swedish Road Administration (Swedish: Statens vägverk) and in 1983 to the National Road Administration (Swedish: Vägverket).
In 1993 the National Swedish Road Safety Office (Trafiksäkerhetsverket) was merged into the agency.
In 2009 the responsibility for the vehicle register and issuing of drivers' licenses, was moved to a new authority, the Swedish Transport Agency. At the same time the department for the actual road work was separated from the National Road Administration into a government owned company, called Svevia. For a number of year this department, then called Vägverket Produktion, was a profit-making organisation competing with private companies.
The agency was merged with the Swedish National Rail Administration on 1 April 2010 to create the new Swedish Transport Administration.
