A prospekt (Russian: проспе́кт, IPA: [prɐˈspʲɛkt] ( listen)) is a broad, multi-lane and very long straight street in urban areas. The term originated in the Russian Empire. It is often translated as avenue; however, it can also be interpreted as parkway since it is common that a prospekt is the main city route (Arterial road).
As an urban area sprawls along transportation routes, the roads outside of city limits called chaussee (French for road surface) often also become converted into prospekts.
In the first years of construction of St Petersburg (in the early 18th century), the city's broad ways were called "perspectiva" (Russian: перспектива, literally, visual or graphical perspective). One of the world-known prospekts of Petersburg is Nevsky Prospekt.
