National roads (literally: road of the rike/realm) in Sweden have road numbers from 1 through 99. The national roads are usually of high quality and sometimes pass through several counties. Roads with lower numbers are in southern Sweden, and roads with higher numbers are in northern Sweden. There are many cases where two or more routes in this system share the same physical road for a considerable distance, giving the country several kilometers of double-numbered road. The network of national roads covers all of Sweden. In 2015, the total length of all national roads (excluding European routes) was 8900 km. The only county that does not have a riksväg is Gotland County. On Gotland and the adjacent island of Öland, the main roads are instead known as county road (länsväg). The national roads are public roads owned by the Government of Sweden and administered by the Swedish Transport Administration. They get a high priority for snow plowing during the winter. The roads' number signs are rectangular with a blue background, white numbers, and a white border.
