Serious bridge accidents in world history

Tangiwai Bridge disaster in New Zealand on December 24, 1953

When part of the wall blocking Ruapehu volcanic lake collapsed on the evening of December 24, 1953, water accompanied by huge silt flowed down the mountainside, carrying trees, rocks and ice into the Whangaehu River. A giant 6m-high wave of water, mud and rocks hit and swept away a concrete pillar of a railway bridge in Tangiwai, nearly 10km from Waiouru.

At 10:21 that night, the Wellington–Auckland night express train with 9 carriages moving at a speed of about 65 km/h arrived at this seriously weakened bridge. When the bridge collapsed under the weight of the train, the train's engine plunged into the river and dragged five second-class carriages into the water.

The force of the floodwaters destroyed four of these carriages while the first-class carriage, Car Z, wobbled on the edge of the ruined bridge for several minutes before continuing to topple into the river. It rolled downstream before coming to rest on the bank as the water level receded.

This was New Zealand's worst railway disaster and the 8th deadliest railway disaster in the world at the time. A total of 151 people out of 285 passengers and crew on board died.

Collapse of railway bridge in Ulyanovsk, Soviet Union in 1983

The river cruise ship named "Aleksandr Suvorov" departed from Rostov to Moscow on June 5, 1983, with an estimated 330 passengers, 30 crew members and 35 service staff on board.

At 10:45 that evening, an auction took place on the upper deck of the ship, attracting a large number of attendees. The ship's captain, Vladimir Kleymenov, retired to his cabin to rest and let helmsman Uvarov and first mate Vladimir Mitenkov take control of the cruise ship.

When this train approached the Ulyanovsk railway bridge over the Volga River, the accident occurred when the train did not pass through its usual passage. From shore, the controller quickly realized the ship was going in the wrong direction. Despite the constant warning messages sent to the ship and the launching of emergency flares, the controllers watched in horror as the "Aleksandr Suvorov" rushed at full speed into the bridge.

A terrible collision completely destroyed the cinema room and the deck where passengers gathered. Matters became worse when the freight train above the bridge derailed and fell onto the "Aleksandr Suvorov" train. The accident killed a total of 177 people. Fortunately, however, the ship remained afloat, thus protecting the surviving passengers and crew until rescue boats arrived 40 minutes later.

This means that the pedestrian bridge on the 4th floor is having to bear twice the intended load. Subsequent investigation revealed that the design of the connecting rods had been changed by the manufacturer at a late stage to simplify assembly.
