Swedish county road

Swedish county roads are roads with road numbers from 100 and upwards in Sweden. The Swedish county roads are public roads maintained by the Swedish [Transport Administration]. There is a total of 82,873 km of county roads in Sweden.
The länsväg roads are divided into three categories:
; Primary county road : Common number series in the range 100-499 throughout Sweden, and can stretch over county borders despite the name.
; Secondary county road : Each county has its own number series in the range of 500-2999.
; Tertiary county road : Each county has its own number series in the range of 3000-9999.
The primary county road number signs are rectangular with a blue background, white numbers, and a white border. The secondary and tertiary county roads are not signed along the roads, and they are prefixed with the Map of [counties of Sweden|county code] of the county they are in.
