The bridge, mainly made out of wood, was located in Uryum village, 3,000 miles from Moscow.
As the truck reached the middle of the bridge, it started failing under the load, eventually falling into the swollen river along with the vehicle.
The driver was later reported to have survived, but the truck could not be recovered from the water.
The suspension bridge was constructed in place of a road bridge that was destroyed during one of the previous floods in the area.
Currently, the residents of Uryum village do not have a way to cross the river after the accident.
Flooding has also damaged a bridge on Russia's Trans-Siberian railway, suspending traffic in the area.
