Blonde Girl Wearing Blue Shoes In The Alley

Use by automobiles
Many alleys, particularly 19th century ones, are wide enough to support automobile traffic. Such alleys are used in residential areas to gain access to garages that were built behind houses after the rise of the automobile. Others can be found in older industrial areas. Because alleys are narrow and often have only enough room for one vehicle to pass at a time, many alleys are one-way only. An alley serving the main entrance of residential, commercial, or industrial buildings, or carrying significant traffic, may be given a separate street name.
