Curly Blonde Girl With A Navel Piercing Shows Off On The Bench Outside On The Alley

(a) A rear access or service road (back lane), which can also sometimes act as part a secondary vehicular network. Many Americans and Canadians think of an alley in these terms first.
(b) A narrow street between the fronts of houses or businesses. This type of alley is found in the older parts of many cities, including American cities like Philadelphia and Boston. Many are open to traffic.
In landscaping, an allée or avenue is traditionally a straight route with a line of trees or large shrubs running along each side. In most cases, the trees planted in an avenue will be all of the same species or cultivar, so as to give uniform appearance along the full length of the avenue. The French term allée is used for avenues planted in parks and landscape gardens, as well as boulevards such as the Grand Allée in Quebec City, Canada, and Karl-Marx-Allee in Berlin.
In older cities and towns in Europe, alleys are often what is left of a medieval street network, or a right of way or ancient footpath. Similar paths also exist in some older North American towns and cities. In some older urban development in North America lanes at the rear of houses, to allow for deliveries and garbage collection, are called alleys. Alleys and ginnels were also the product of the 1875 Public Health Act in the United Kingdom, where usually alleys run along the back of streets of terraced houses, with ginnels connecting them to the street every fifth house. Alleys may be paved, or unpaved, and a blind alley is a cul-de-sac. Modern urban developments may also provide a service road to allow for waste collection, or rear access for fire engines and parking.
