A super highway is typically a multi-lane roadway designed for high-speed traffic. In some regions, it may be referred to as a freeway, expressway, or motorway. Synonyms for super highway may vary depending on location, but can also include autoroute, autostrada, interstate, turnpike, or toll road. Opened in 1956, the U.S. Interstate Highway system has been a model for super highway construction around the world. While they have made travel more convenient and efficient, super highways can also have negative impacts on nearby communities, such as noise pollution and loss of property value. Understanding regional terminology for super highways can be helpful when traveling or researching transportation options.
