On the eve of City Day, motorists were warned that it would be difficult to drive through the center due to festive events. In particular, at 12 noon, with the participation of Patriarch Kirill, they were going to hold a religious procession from St. Isaac's Cathedral to the Synod building, for which it was planned to block St. Isaac's Square and the streets adjacent to it. Also, in connection with the arrival of the patriarch, traffic at the Alexander Nevsky Lavra was limited.
