Bolshoy Prospekt (Petrograd Side)

Bolshoy Prospekt of Petrograd Side (Russian: Большой проспект Петроградской стороны) is a large avenue in Petrogradsky District of Saint Petersburg, Russia, crossing Petrogradsky Island and spanning from Tuchkov Bridge across the Malaya Neva to Petropavlovsky Bridge across the Karpovka River.

In 1918–1944 the avenue was named Karl Liebknecht Prospekt (проспект Карла Либкнехта).

The street is served by the stations Sportivnaya and Petrogradskaya of Saint Petersburg Metro.

For most of its length, excluding the section between the Karpovka and Kamennoostrovsky Prospekt, Bolshoy Prospekt is a straight one-way street with south-west bound traffic heading towards Tuchkov Bridge.

The buildings along the street mostly dates back to the late 19th – early 20th century and are designed in the Art Nouveau, National Romantic and Neoclassical styles, as well as other revivals.
