An "Av" or "Avenue" is a type of street typically found in urban areas. Avenues are often wider than regular streets and may be lined with trees, buildings, or shops. They usually run perpendicular to streets and can serve as major thoroughfares for traffic, connecting different parts of a city. Avenues are commonly named after notable figures, places, or events, contributing to the cultural identity of a city. For example, 5th Avenue in New York City is famous for its shopping and landmarks, while Avenue des Champs-Élysées in Paris is known for its cafes and theaters.
