context: Since 1860, a horse tram began to walk along the avenue, from the end of 1908 a tram was started instead (the tram traffic on the avenue was interrupted in the first blockade winter, but resumed already in 1942 [3]), and from 1947 instead of a tram, a trolleybus began to walk. By 1955, the tram rails were completely removed [4]. Buses also run along the avenue, and minibuses from the 1990s.
question: In what year did the transport go along Bolshoy Prospekt of the Petrograd Side?
