Highways in Bulgaria are dual carriageways, grade separated with controlled-access, designed for high speeds. In 2012, legislation amendments defined two types of highways: motorways and expressways. The main differences are that motorways have an alternative route and the maximum allowed speed limit is 140 km/h (87 mph), while expressways do not and the speed limit is 120 km/h (75 mph). As of November 2025, a total of 911 kilometers of motorways are in service.
