A street is a public thoroughfare in a city, town or village, typically lined with buildings on one or both sides. Streets often include pavements (sidewalks), pedestrian crossings, and sometimes amenities like streetlights or benches. A street can be as simple as a level patch of dirt, but is more often paved with a hard, durable surface such as tarmac, concrete, cobblestone or brick. It can be designed for both social activity and movement.
Originally, the word street simply meant a paved road (Latin: via strata). The word street is still sometimes used informally as a synonym for road, for example in connection with the ancient Watling Street, but city residents and urban planners draw a significant modern distinction: a road's main function is transportation, while streets facilitate public interaction. Examples of streets include pedestrian streets, alleys, and city-centre streets too crowded for motor vehicles to pass. Conversely, highways and motorways are types of roads, but few would refer to them as streets.
When a street needs to support heavy through traffic, it can come to resemble a road. Such a street-road combination is known as a stroad.
