Main Street is a generic phrase used to denote a primary retail street of a village, town or small city in many parts of the world. It is usually a focal point for shops and retailers in the central business district, and is most often used in reference to retailing and socializing.
The term is commonly used in Ireland, Scotland, the United States, Canada, and less often in Australia and New Zealand. In most of the United Kingdom the common description is High Street. However, the term "Main Street" is sometimes used in the UK, for instance, in the village of Sutton Cheney. In Jamaica the term is Front Street. In some parts of the south west of England the equivalent used is Fore Street.
In some larger cities, there may be several Main Streets, each relating to a specific neighborhood or formerly separate city, rather than the city as a whole. In many larger U.S. cities "Main Street" is a U.S. Highway; "Main Street of America" branding was used to promote U.S. Route 66 in its heyday.(Wikipedia)
