Why the bridge in Primorye began to collapse. It lasted 53 years

Rusted metal in the structure led to the accident

The collapse of the bridge in Primorye occurred due to corrosion of metal structures. This was reported to journalists by the head of the Investigative Department of the Investigative Committee of the Russian Federation for the Primorsky Territory, Sergei Zhavoronkov.

According to him, the examination showed that the metal structures of the bridge were badly rusted. This led to a decrease in their bearing capacity and, as a result, to the collapse of the structure.

The bridge was built 53 years ago

The bridge that collapsed in Primorye was built in 1970. It was intended for the passage of vehicles weighing up to 60 tons. However, in recent years, heavier trucks have often passed over it.

In addition, the bridge was not properly maintained. This led to the fact that its metal structures began to rust. As a result, the bridge could not withstand the load and collapsed.

The accident could have been avoided

The collapse of the bridge in Primorye could have been avoided if the metal structures had been properly maintained. This would have prevented corrosion and reduced the risk of collapse.

In addition, it was necessary to restrict the passage of heavy vehicles over the bridge. This would also have helped to extend its service life.

Conclusions

The collapse of the bridge in Primorye is a serious accident that could have been avoided. The causes of the collapse were corrosion of metal structures and improper maintenance of the bridge.

In order to prevent similar accidents in the future, it is necessary to properly maintain bridges and restrict the passage of heavy vehicles over them.
