1 August (13 June)
1959, young people from across the entire region arrived in Akmola to take part in festive events. A regional youth festival was being held. On the second day of the festival —
2 August (14 June), at 13:46 local time (UTC+5), the bridge over the Yesil River was unable to withstand the load and collapsed. The only police officer present that day together with his spouse,
Nurmukhambet Kozhakhmetov, began rescuing people who were drowning. Because the incident occurred during festive events, people did not immediately realize how the bridge in front of them had collapsed. Since reaching the left bank of Akmola was practically impossible, ambulances and emergency services arrived only from the right bank. ==Classification==
