1. Street, alley, avenue, boulevard all refer to public ways or roads in municipal areas. A street is a road in a village, town, or city, especially a road lined with buildings. An alley is a narrow street or footway, especially at the rear of or between rows of buildings or lots. An avenue is properly a prominent street, often one bordered by fine residences and impressive buildings, or with a row of trees on each side. A boulevard is a beautiful, broad street, lined with rows of stately trees, especially used as a promenade. In some cities street and avenue are used interchangeably, the only difference being that those running one direction (say, north and south) are given one designation and those crossing them are given the other.
